• Fixed serious buffer overrun in FFmpeg logging code.

Consumers

• FFmpeg consumer:
  • Fixed long overdue bug where HD material was always recorded using the BT.601 color matrix instead of the BT.709 color matrix. RGB codecs like qtrle was never affected but all the YCbCr based codecs were.
  • Fixed bug in parsing of paths containing -.
  • Fixed bugs where previously effective arguments like -pix_fmt were ignored.
  • Fixed bug where interlaced channels where not recorded correctly for some codecs.
• DeckLink consumer:
  • Rewrote the frame hand-off between send() and ScheduledFrameCompleted() in a way that hopefully resolves all dead-lock scenarios previously possible.
• Bluefish consumer:
  • Largely rewritten against newest SDK Driver 5.11.0.47 (Satchit Nambiar and James Wise sponsored by Bluefish444):
    • Added support for Epoch Neutron and Supernova CG. All current Epoch cards are now supported.
    • Added support for for multiple SDI channels per card. 1 to 4 channels per Bluefish444 card depending on model and firmware.
    • Added support for single SDI output, complementing existing external key output support.
    • Added support for internal key using the Bluefish444 hardware keyer.
• Screen consumer:
  • Fixed full screen mode.

Producers

• FFmpeg producer:
  • Increased the max number of frames that audio/video can be badly interleaved with (Dimitry Ishenko).
  • Fixed bug where decoders sometimes requires more than one video packet to decode the first frame.
  • Added support for IN and OUT parameters (Dimitry Ishenko).
  • Added DV/HDV video device support under Linux (Walter Sonius).
  • Remove unused flags variable in queued_seek (Dimitry Ishenko).
  • Now recognizes .ts files without probing contents (Ovidijus Striaukas).
  • Fixed uninitialized value causing initial log printout to usually say that clips are interlaced when they are not.
• Destroy producer proxy:
  • Created workaround for bug in FFmpeg where every new thread used to cleanup caused handles to leak (not sure why). Reduced the effect by using only one thread for all producer destructions.
• Framerate producer:
  • Fixed bug when INFO was used on a not yet playing framerate producer.
• HTML producer:
  • Fixed bug where only URL:s with . in them where recognized.
• Image producer:
  • Added LENGTH parameter to allow for queueing with LOADBG AUTO.
  • Fixed inconsistency in what file extensions are supported vs listed in CLS/CINF.
• Layer producer:
  • Fixed serious bug where a circular reference of layer producers caused a stack overflow and server crash.
  • Can now route from layer on a channel with an incompatible framerate.
• Channel producer:
  • Can now route from channel with an incompatible framerate.
  • Deinterlaces interlaced content from source channel.
  • Added optional NO_AUTO_DEINTERLACE parameter to opt out of the mentioned deinterlacing.
• Scene producer:
  • Added abs(), floor(), to_lower(), to_upper() and length() functions to the expression language.
  • Created XML Schema for the *.scene XML format. Allows for IDE-like auto- completion, API documentation and validation.
  • Added possibility to specify the width and height of a layer instead of letting the producer on the layer decide.
  • Added global variables scene_width, scene_height and fps.
  • Made it possible to use expressions in keyframe values.
  • Fixed serious bug where uninitialized values were used.
  • Created more example scenes.
  • Can now forward CALL, CG PLAY, CG STOP, CG NEXT and CG INVOKE to the producer on a layer.
• CG proxy wrapper producer:
  • New in 2.1.0.
  • Allows all CG producers to be used as an ordinary producer inside a layer in a scene.
  • Allows the Scene producer to know what variables are available in a template.
• Color producer:
  • Now has support for gradients.
• PSD producer:
  • Added support for centered and right justified text.
• Text producer:
  • Fixed bug where tracking contributed to the overall text width on the last character.

Mixer

• Fixed bug in the contrast/saturation/brightness code where the wrong luma coefficients was used.
• Rewrote the chroma key code to support variable hue, instead of fixed green or blue. Threshold setting was removed in favour of separate hue width, minimum saturation and minimum brightness constraints. Also a much more effective spill suppression method was implemented.
• Fixed bug where glReadPixels() was done from the last drawn to texture instead of always from the target texture. This means that for example a MIXER KEYER layer without a layer above to key, as well as a separate alpha file with MIXER OPACITY 0 now works as expected.
• Fixed bug where already drawn GL_QUADS were not composited against, causing for example italic texts to be rendered incorrectly in the text_producer.

AMCP

• INFO PATHS now adds all the path elements even if they are using the default values.
• MIXER CHROMA syntax deprecated (still supported) in favour of the more advanced syntax required by the rewritten chroma key code.
• Added special command REQ that can be prepended before any command to identify the response with a client specified request id, allowing a client to know exactly what asynchronous response matched a specific request.
• Added support for listing contents of a specific directory for CLS, TLS, DATA LIST and THUMBNAIL LIST.
• Fixed bug where CINF only returned the first match.
• Fixed bug where a client closing the connection after BYE instead of letting the server close the connection caused an exception to be logged.

CasparCG 2.1.0 Beta 1 (w.r.t 2.0.7 Stable)

General

• 64 bit!
• Linux support!
  • Moved to CMake build system for better platform independence.
    • Contributions before build system switch (not w.r.t 2.0.7 Stable):
      • gitrev.bat adaptions for 2.1 (Thomas Kaltz III).
  • Thanks to our already heavy use of the pimpl idiom, abstracting platform specifics was easily done by having different versions of the .cpp files included in the build depending on target platform. No #ifdef necessary, except for in header only platform specific code.
  • Flash, Bluefish and NewTek modules are not ported to the Linux build.
  • Contributions during development (not w.r.t 2.0.7 Stable):
    • Fixed compilation problems in Linux build (Dimitry Ishenko).
    • Fixed compilation problem in GCC 5 (Krzysztof Pyrkosz).
    • Fixed thumbnail image saving on Linux (Krzysztof Pyrkosz).
    • Fixed compilation problem in PSD module (Krzysztof Pyrkosz).
• Major code refactoring:
  • Mixer abstraction so different implementations can be created. Currently CPU mixer and GPU mixer (previously the usage of the GPU was mandatory) exists.
  • Flattened folder structure for easier inclusion of header files.
  • Many classes renamed to better describe the abstractions they provide.
  • Sink parameters usually taken by value and moved into place instead of taken by const reference as previously done.
  • Old Windows specific AsyncEventServer class has been replaced by platform independent implementation based on Boost.Asio.
  • Pimpl classes are now stack allocated with internal shared_ptr to implementation, instead of both handle and body being dynamically allocated. This means that objects are now often passed by value instead of via safe_ptr/shared_ptr, because they are internally reference counted.
  • Protocol strategies are now easier to implement correctly, because of separation of state between different client connections.
  • Complete AMCP command refactoring.
  • On-line help system that forces the developer to document AMCP commands, producer syntaxes and consumer syntaxes making the documentation coupled to the code, which is great.
    • Added missing help for VERSION command (Jesper Stærkær).
  • Upgraded Windows build to target Visual Studio 2015 making it possible to use the C++11 features also supported by GCC 4.8 which is targeted on Linux.
    • Fixed compilation problems in Visual Studio 2015 Update 1 (Roman Tarasov)
  • Created abstraction of the different forms of templates (flash, html, psd and scene). Each module registers itself as a CG producer provides. All CG commands transparently works with all of them.
  • Audio mixer now uses double samples instead of float samples to fully accommodate all int32 samples.
  • Reduced coupling between core and modules (and modules and modules):
    • Modules can register system info providers to contribute to INFO SYSTEM.
    • XML configuration factories for adding support for new consumer elements in casparcg.config.
    • Server startup hooks can be registered (used by HTML producer to fork its sub process).
    • Version providers can contribute content to the VERSION command.
• Refactored multichannel audio support to use FFmpeg's PAN filter and simplified the configuration a lot.
• Upgraded most third party libraries we depend on.
• Some unit tests have been created.
• Renamed README.txt to README, CHANGES.txt to CHANGELOG and LICENSE.txt to LICENSE
• Created README.md for github front page in addition to README which is distributed with builds.
• README file updates (Jonas Hummelstrand).
• Created BUILDING file describing how to build the server on Windows and Linux.
• Diagnostics:
  • Now also sent over OSC.
  • Diag window is now scrollable and without squeezing of graphs.
  • Contextual information such as video channel and video layer now included in graphs.
• Logging:
  • Implemented a TCP server, simply sending every log line to each connected client. Default port is 3250.
  • Changed default log level to info and moved debug statements that are interesting in a production system to info.
  • Try to not log full stack traces when user error is the cause. Stacktraces should ideally only be logged when a system error or a programming error has occurred.
  • More contextual information about an error added to exceptions. An example of this is that XML configuration errors now cause the XPath of the error is logged.
  • Improved the readability of the log format.
  • Added optional calltrace.log for logging method calls. Allows for trace logging to be enabled while calltracing is disabled etc.

OSC

• Improved message formatting performance.
• Added possibility to disable sending OSC to connected AMCP clients.
• Fixed inconsistent element name predefined_client to predefined-client in casparcg.config (Krzysztof Pyrkosz).

Consumers

• System audio consumer:
  • Pushes data to openal instead of being callbacked by SFML when data is needed.
  • Added possibility to specify the expected delay in the sound card. Might help get better consumer synchronization.
• Screen consumer:
  • Added mouse interaction support, usable by the producers running on the video channel.
• FFmpeg consumer:
  • Replaced by Streaming Consumer after it was adapted to support everything that FFmpeg Consumer did.
  • Added support for recording all audio channels into separate mono audio streams.
  • Now sends recording progress via OSC.
• SyncTo consumer:
  • New in 2.1.0.
  • Allows the pace of a channel to follow another channel. This is useful for virtual "precomp" channels without a DeckLink consumer to pace it.
• DeckLink consumer:
  • Added workaround for timescale bug found in Decklink SDK 10.7.
  • Now ScheduledFrameCompleted is no longer only used for video scheduling but for audio as well, simplifying the code a lot.
• iVGA consumer:
  • No longer provides sync to the video channel.
  • Supports NewTek NDI out of the box just by upgrading the Processing.AirSend library.

Producers

• Scene producer:
  • New in 2.1.0.
  • Utilizes CasparCG concepts such as producers, mixer transforms and uses them in a nested way to form infinite number of sub layers. Think movie clip in Flash.
  • A scene consists of variables, layers, timelines and marks (intro and outro for example).
  • Mostly for use by other producers but comes with a XML based producer that is a registered CG producer and shows up in TLS.
  • Enables frame accurate compositions and animations.
  • Has a powerful variable binding system (think expressions in After Effects or JavaFX Bindings).
• PSD producer:
  • New in 2.1.0.
  • Parses PSD files and sets up a scene for the Scene producer to display.
  • Text layers based on CG parameters.
  • Supports Photoshop timeline.
  • Uses Photoshop comment key-frames to describe where intro and outro (CG PLAY and CG STOP) should be in the timeline.
  • Shows up as regular templates in TLS.
• Text producer:
  • New in 2.1.0.
  • Renders text using FreeType library.
  • Is used by the PSD producer for dynamic text layers.
• Image scroll producer:
  • Speed can be changed while running using a CALL. The speed change can be tweened.
  • Added support for an absolute end time so that the duration is calculated based on when PLAY is called for shows when an exact end time is important.
• Image producer:
  • Fixed bug where too large (OpenGL limit) images were accepted, causing problems during thumbnail generation.
• Framerate producer:
  • New in 2.1.0.
  • Wraps a producer with one framerate and converts it to another. It is not usable on its own but is utilized in the FFmpeg producer and the DeckLink consumer.
  • Supports different interpolation algorithms. Currently a no-op drop-and-repeat mode and a two different frame blending modes.
  • It also supports changing the speed on demand with tweening support.
• FFmpeg producer:
  • Supports decoding all audio streams from a clip. Useful with .mxf files which usually have separate mono streams for every audio channel.
  • No longer do framerate conversion (half or double), but delegates that task to the Framerate producer.
  • Added support for v4l2 devices.
  • Added relative and "from end" seeking (Dimitry Ishenko).
  • Contributions during development (not w.r.t 2.0.7 Stable):

  • Reimplemented requestAnimationFrame handling in Javascript instead of C++.
  • Implemented cancelAnimationFrame.
  • Increased animation smoothness in HTML Producer with interlaced video modes.
  • Added remote debugging support.
  • Added mouse interaction support by utilizing the Screen consumer's new interaction support.
• Flash Producer:
  • Contributions during development (not w.r.t 2.0.7 Stable):
    • Workaround for flickering with high CPU usage and CPU accelerator (Robert Nagy)

AMCP

• TLS has a new column for "template type" for clients that want to differentiate between html and flash for example.
• SET CHANNEL_LAYOUT added to be able to change the audio channel layout of a video channel at runtime.
• HELP command added for accessing the new on-line help system.
• FLS added to list the fonts usable by the Text producer.
• LOCK command added for controlling/gaining exclusive access to a video channel.
• LOG CATEGORY command added to enable/disable the new log categories.
• SWAP command now optionally supports swapping the transforms as well as the layers.
• VERSION command can now provide CEF version.

CasparCG Server 2.0.7 Stable (as compared to CasparCG Server 2.0.7 Beta 2)

General

• Added support for using a different configuration file at startup than the default casparcg.config by simply adding the name of the file to use as the first command line argument to casparcg.exe.
• Upgraded FFmpeg to latest stable.
• Created build script.
• Fixed bug where both layer_producer and channel_producer display:s and empty/late first frame when the producer is called before the consumer in the other end has received the first frame.
• Added rudimentary support for audio for layer_producer and channel_producer.
• Upgraded DeckLink SDK to 10.1.4, bringing new 2K and 4K DCI video modes. New template hosts also available for those modes.
• General bug fixes (mostly memory and resource leaks, some serious).
• Updated Boost to version 1.57
• Frontend no longer maintained and therefore not included in the release.

Mixer

• Added support for rotation.
• Added support for changing the anchor point around which fill_translation, fill_scale and rotation will be done from.
• Added support for perspective correct corner pinning.
• Added support for mipmapped textures with anisotropic filtering for increased downscaling quality. Whether to enable by default can be configured in casparcg.config.
• Added support for cropping a layer. Not the same as clipping.

AMCP

• Added RESUME command to complement PAUSE. (Peter Keuter)

• To support the new mixer features the following commands has been added:

  • MIXER ANCHOR -- will return or modify the anchor point for a layer (default is 0 0 for backwards compatibility). Example: MIXER 1-10 ANCHOR 0.5 0.5 ...for changing the anchor to the middle of the layer (a MIXER 1-10 FILL 0.5 0.5 1 1 will be necessary to place the layer at the same place on screen as it was before).

  • MIXER ROTATION -- will return or modify the angle of which a layer is rotated by (clockwise degrees) around the point specified by ANCHOR.

  • MIXER PERSPECTIVE -- will return or modify the corners of the perspective transformation of a layer. One X Y pair for each corner (order upper left, upper right, lower right and lower left). Example: MIXER 1-10 PERSPECTIVE 0.4 0.4 0.6 0.4 1 1 0 1

  • MIXER MIPMAP -- will return or modify whether to enable mipmapping of textures produced on a layer. Only frames produced after a change will be affected. So for example image_producer will not be affected while the image is displayed.

  • MIXER CROP -- will return or modify how textures on a layer will be cropped. One X Y pair each for the upper left corner and for the lower right corner.

• Added INFO QUEUES command for debugging AMCP command queues. Useful for debugging command queue overflows, where a command is deadlocked. Hopefully always accessible via console, even though the TCP command queue may be full.

• Added GL command:

  • GL INFO prints information about device buffers and host buffers.
  • GL GC garbage collects pooled but unused GL resources.

• Added INFO THREADS command listing the known threads and their descriptive names. Can be matched against the thread id column of log entries.

Consumers

• Removed blocking_decklink_consumer. It was more like an experiment at best and its usefulness was questionable.
• Added a 10 second time-out for consumer sends, to detect/recover from blocked consumers.
• Some consumers which are usually added and removed during playout (for example ffmpeg_consumer, streaming_consumer and channel_consumer) no longer affect the presentation time on other consumers. Previously a lag on the SDI output could be seen when adding such consumers.

HTML producer

• No longer tries to play all files with a . in their name. (Georgi Chorbadzhiyski)
• Reimplemented using CEF3 instead of Berkelium, which enables use of WebGL and more. CEF3 is actively maintained, which Berkelium is not. (Robert Nagy)
• Implements a custom version of window.requestAnimationFrame which will follow the pace of the channel, for perfectly smooth animations.
• No longer manually interlaces frames, to allow for mixer fill transforms without artifacts.
• Now uses CEF3 event loop to avoid 100% CPU core usage.

CasparCG Server 2.0.7 Beta 2 (as compared to CasparCG Server 2.0.7 Beta 1)

General

• Added sending of OSC messages for channel_grid channel in addition to regular channels.

Producers

• FFmpeg: Reports correct nb_frames() when using SEEK (Thomas Kaltz III)
• Flash: Fixed bug where CG PLAY, CG INVOKE did not work.

Consumers

• channel_consumer: Added support for more than one channel_consumer per channel.

• decklink_consumer: Added support for a single instance of the consumer to manage a separate key output for use with DeckLink Duo/Quad cards:

  1 2 external_separate_device

  ...in the configuration will enable the feature. The value of defaults to the value of + 1.

• synchronizing_consumer: Removed in favour of a single decklink_consumer managing both fill and key device.

• streaming_consumer: A new implementation of ffmpeg_consumer with added support for streaming and other PTS dependent protocols. Examples:

  udp://localhost:5004 -vcodec libx264 -tune zerolatency -preset ultrafast -crf 25 -format mpegts -vf scale=240:180

  ...in configuration or:

  ADD 1 STREAM udp://localhost:5004 -vcodec libx264 -tune zerolatency -preset ultrafast -crf 25 -format mpegts -vf scale=240:180

  ...via AMCP. (Robert Nagy sponsored by Ericsson Broadcasting Services)

• newtek_ivga_consumer: Added support for iVGA consumer to not provide channel sync even though connected. Useful for iVGA clients that downloads as fast as possible instead of in frame-rate pace, like Wirecast. To enable:

  false

  ...in config to not provide channel sync when connected. The default is true.

AMCP

• Added support in ADD and REMOVE for a placeholder <CLIENT_IP_ADDRESS> which will resolve to the connected AMCP client's IPV4 address.
• Fixed bug where AMCP commands split into multiple TCP packets where not correctly parsed (http://casparcg.com/forum/viewtopic.php?f=3&t=2480)

CasparCG Server 2.0.7 Beta 1 (as compared to 2.0.6 Stable)

General

• FFmpeg: Upgraded to master and adapted CasparCG to FFmpeg API changes (Robert Nagy sponsored by SVT)
• FFmpeg: Fixed problem with frame count calculation (Thomas Kaltz III)
• Fixed broken CG UPDATE.

Producers

• New HTML producer has been created (Robert Nagy sponsored by Flemish Radio and Television Broadcasting Organization, VRT)

CasparCG Server 2.0.6 Stable (as compared to 2.0.4 Stable)

General

• iVGA: Allow for the server to work without Processing.AirSend.x86.dll to prevent a possible GPL violation. It is available as a separate optional download.
• iVGA: Only provide sync to channel while connected, to prevent channel ticking too fast.
• FFmpeg: Fixed bug during deinterlace-bob-reinterlace where output fields were offset by one field in relation to input fields.
• FFmpeg: Fixed bug in ffmpeg_consumer where an access violation occurred during destruction.
• FFmpeg: Improved seeking. (Robert Nagy and Thomas Kaltz III)
• Frontend: Only writes elements to casparcg.config which overrides a default value to keep the file as compact as possible.
• System audio: Patched sfml-audio to work better with oal-consumer and therefore removed PortAudio as the system audio implementation and went back to oal.
• Flash: Changed so that the initial buffer fill of frames is rendered at a frame-duration pace instead of as fast as possible. Otherwise time based animations render incorrectly. During buffer recovery, a higher paced rendering takes place, but still not as fast as possible, which can cause animations to be somewhat incorrectly rendered. This is the only way though if we want the buffer to be able to recover after depletion.
• Fixed race condition during server shutdown.
• OSC: outgoing audio levels from the audio mixer for each audio channel is now transmitted (pFS and dBFS). (Thomas Kaltz III)
• Stage: Fixed bug where tweened transforms were only ticked when a corresponding layer existed.
• Screen consumer: Added borderless option and correct handling of name option. (Thomas Kaltz III)
• AMCP: CLS now reports duration and framerate for MOVIE files were information is possible to extract. (Robert Nagy)
• Version bump to keep up with CasparCG Client version.

CasparCG Server 2.0.4 Stable (as compared to 2.0.4 Beta 1)

General

• Can now open media with file names that only consist of digits. (Cambell Prince)
• Miscellaneous stability and performance improvements.

Video mixer

• Conditional compilation of chroma key support and straight alpha output support in shader (just like with blend-modes) because of performance impact even when not in use on a layer or on a channel. New element added to configuration for turning on mixer features that not everybody would want to pay for (performance-wise.) blend-modes also moved into this element.
• Fixed bug where MIXER LEVELS interpreted arguments in the wrong order, so that gamma was interpreted as max_input and vice versa.

Consumers

• Added support for NewTek iVGA, which enables the use of CasparCG Server fill+key output(s) as input source(s) to a NewTek TriCaster without requiring video card(s) in the CasparCG Server machine, or taking up inputs in the TriCaster. element in config enables iVGA on a channel. (Robert Nagy sponsored by NewTek)
• DeckLink: Created custom decklink allocator to reduce the memory footprint.
• Replaced usage of SFML for with PortAudio, because of problems with SFML since change to static linkage. Also PortAudio seems to give lower latency.

Producers

• FFmpeg: Added support for arbitrary FFmpeg options/parameters in ffmpeg_producer. (Cambell Prince)
• Flash: Flash Player 11.8 now tested and fully supported.
• Flash: No longer starts a Flash Player to service CG commands that mean nothing without an already running Flash Player.
• Flash: globally serialize initialization and destruction of Flash Players, to avoid race conditions in Flash.
• Flash: changed so that the Flash buffer is filled with Flash Player generated content at initialization instead of empty frames.

OSC

• Performance improvements. (Robert Nagy sponsored by Boffins Technologies)
• Never sends old values to OSC receivers. Collects the latest value of each path logged since last UDP send, and sends the new UDP packet (to each subscribing OSC receiver) with the values collected. (Robert Nagy sponsored by Boffins Technologies)
• Batches as many OSC messages as possible in an OSC bundle to reduce the number of UDP packets sent. Breakup into separate packages if necessary to avoid fragmentation. (Robert Nagy sponsored by Boffins Technologies)
• Removed usage of Microsoft Agents library (Server ran out of memory after a while) in favour of direct synchronous invocations.

CasparCG Server 2.0.4 Beta 1 (as compared to 2.0.3 Stable)

General

• Front-end GUI for simplified configuration and easy access to common tasks. (Thomas Kaltz III and Jeff Lafforgue)

• Added support for video and images file thumbnail generation. By default the media directory is scanned every 5 seconds for new/modified/removed files and thumbnails are generated/regenerated/removed accordingly.

• Support for new video modes: 1556p2398, 1556p2400, 1556p2500, 2160p2398, 2160p2400, 2160p2500, 2160p2997 and 2160p3000.

• Experimental ATI graphics card support by using static linking against SFML instead of dynamic. Should improve ATI GPU support, but needs testing.

• Added support for playback and pass-through of up to 16 audio channels. See http://casparcg.com/forum/viewtopic.php?f=3&t=1453 for more information.

• Optimizations in AMCP protocol implementations for large incoming messages, for example base64 encoded PNG images.

• Logging output now includes milliseconds and has modified format: YYYY-MM-DD hh:mm:ss.zzz

• Improved audio playback with 720p5994 and 720p6000 channels.

• An attempt to improve output synchronization of consumers has been made. Use for example:

  1 true 2 true

  ...to instruct the server to keep both DeckLink consumers in sync with each other. Consider this experimental, so don't wrap everything in unless synchronization of consumer outputs is needed. For synchronization to be effective all synchronized cards must have genlock reference signal connected.

• Transfer of source code and issue tracker to github. (Thomas Kaltz III)

Layer

• Fixed a problem where the first frame was not always shown on LOAD. (Robert Nagy)

Stage

• Support for layer consumers for listening to frames coming out of producers. (Cambell Prince)

Audio mixer

• Added support for a master volume mixer setting for each channel.

Video mixer

• Added support for chroma keying. (Cambell Prince)
• Fixed bug where MIXER CONTRAST set to < 1 can cause transparency issues.
• Experimental support for straight alpha output.

Consumers

• Avoid that the FFmpeg consumer blocks the channel output when it can't keep up with the frame rate (drops frames instead).
• Added support for to create a separate key and fill file when recording with the FFmpeg consumer. Add the SEPARATE_KEY parameter to the FFmpeg consumer parameter list. The key file will get the _A file name suffix to be picked up by the separated_producer when doing playback.
• The Image consumer now writes to the media folder instead of the data folder.
• Fixed bug in DeckLink consumer where we submit too few audio samples to the driver when the video format has a frame rate > 50.
• Added another experimental DeckLink consumer implementation where scheduled playback is not used, but a similar approach as in the bluefish consumer where we wait for a frame to be displayed and then display the next frame. It is configured via a consumer element. The benefits of this consumer is lower latency and more deterministic synchronization between multiple instances (should not need to be wrapped in a element when separated key/fill is used).

Producers

• Added support for playing .swf files using the Flash producer. (Robert Nagy)
• Image producer premultiplies PNG images with their alpha.
• Image producer can load a PNG image encoded as base64 via: PLAY 1-0 [PNG_BASE64]
• FFmpeg producer can now use a directshow input filters: PLAY 1-10 "dshow://video=Some Camera" (Cambell Prince, Julian Waller and Robert Nagy)
• New layer producer which directs the output of a layer to another layer via a layer consumer. (Cambell Prince)

AMCP

• The master volume feature is controlled via the MASTERVOLUME MIXER parameter. Example: MIXER 1 MASTERVOLUME 0.5
• THUMBNAIL LIST/RETRIEVE/GENERATE/GENERATE_ALL command was added to support the thumbnail feature.
• ADD 1 FILE output.mov SEPARATE_KEY activates the separate key feature of the FFmpeg consumer creating an additional output_a.mov containing only the key.
• Added KILL command for shutting down the server without console access.
• Added RESTART command for shutting down the server in the same way as KILL except that the return code from CasparCG Server is 5 instead of 0, which can be used by parent process to take other actions. The 'casparcg_auto_restart.bat' script restarts the server if the return code is 5.
• DATA RETRIEVE now returns linefeeds encoded as an actual linefeed (the single character 0x0a) instead of the previous two characters: \ followed by n.
• MIXER CHROMA command added to control the chroma keying. Example: MIXER 1-1 CHROMA GREEN|BLUE 0.10 0.04 (Cambell Prince)
• Fixed bug where MIXER FILL overrides any previous MIXER CLIP on the same layer. The bug-fix also has the side effect of supporting negative scale on MIXER FILL, causing the image to be flipped.
• MIXER STRAIGHT_ALPHA_OUTPUT added to control whether to output straight alpha or not.
• Added INFO DELAY and INFO - DELAY commands for showing some delay measurements.
• PLAY 1-1 2-10 creates a layer producer on 1-1 redirecting the output of 2-10. (Cambell Prince)

OSC

• Support for sending OSC messages over UDP to either a predefined set of clients (servers in the OSC sense) or dynamically to the ip addresses of the currently connected AMCP clients. (Robert Nagy sponsored by Boffins Technologies)

  • Now deinterlaces to two separate frames so for example 50i will no longer be converted to 25p but instead to 50p for smooth playback of interlaced content.
• DeckLink consumer now logs whether a reference signal is detected or not.

Producers

• Image scroll producer:
  • Field-rate motion instead of frame-rate motion with interlaced video formats. This can be overridden by giving the PROGRESSIVE parameter.
  • SPEED parameter now defines pixels per frame/field instead of half pixels per frame. The scrolling direction is also reversed so SPEED 0.5 is the previous equivalent of SPEED -1. Movements are done with sub-pixel accuracy.
  • Fixed incorrect starting position of image.
