| published: true | ||

|
|
||
| # Welcome | ||
| # HDMI2USB | ||
|
|
||
| **Welcome to TimVideos.us!** | ||
| The HDMI2USB project aims to develop open hardware for conference, meeting and | ||
| user group recording. | ||
|
|
||
| **TimVideos.us** is a _group_ of exciting projects which together create a system for doing both _recording and live event streaming_ for **conferences**, **meetings**, **user groups** and **other** presentations. | ||
| # Boards | ||
|
|
||
| We hope that, through our _projects_, the costs and expertise currently required to produce live streaming events will be reduced to near zero. We wish to develop a system where everyone has the ability to record presentations and host live remote participants across the globe. | ||
| ## Actively Supported | ||
|
|
||
| Whether you want to work hands-on with hardware or code in a variety of languages, we have a project for you. Join the team! This information should help you explore the projects and learn how to get started. | ||

| | [[HDMI2USB]] | [(C)](http://github.com/timvideos/HDMI2USB) [(M)](https://groups.google.com/group/hdmi2usb?hl=en-GB) [(I)](irc://irc.freenode.org/#hdmi2usb) | HDMI2USB is hardware for capturing HDMI, DVI and DisplayPort data. By capturing in high quality what is being presented locally it facilitates sharing with remote users and creates great recording for later viewing. The HDMI2USB hardware can also capture the HDMI output from cameras. | | ||
| | [[gst-switch]] | [(C)](http://github.com/timvideos/gst-switch) [(M)](https://groups.google.com/group/gst-switch) [(I)](irc://irc.freenode.org/#gst-switch) | [[gst-switch]] aims to do interactive live mixing of incoming video streams, designed to meet the needs of conference recording. Designed as a flexible replacement for DVSwitch, and based around GStreamer. | | ||
| | speakertrack | [(C)](http://github.com/timvideos/gst-switch) | Speakertrack is an extension to GStreamer and gst-switch to allow automatic tracking of speakers using remotely-operated PTZ cameras rather then relying on a camera operator. | | ||

| <ul> | ||
| <li>[1]: <a name="atlys-hdmi-input"></a> | ||
| The Atlys board has the hot plug pin hard wired, hot plug detection and control | ||
| is not supported on this board. The CEC pin is also unconnected. | ||
| </li> | ||
|
|
||
| <li>[2]: <a name="atlys-hdmi-output1"></a> | ||

| <li>[3]: <a name="atlys-hdmi-output2"></a> | ||
| </li> | ||
|
|
||
| <li>[4]: <a name="opsys-hdmi"></a> | ||
| On the Numato Opsis board, all the HDMI pins are under the FPGA control. This | ||
| means the board support hot plug detection and control and also CEC support | ||
| (which is missing from the firmware). | ||
| </li> | ||
|
|
||
| <li>[5]:<a name="atlys-pmod"></a> | ||
| The PMOD header on the Atlys board is shared with the micro-HDMI connector. | ||
| Only one can be in use at any one time. | ||

The applications it supports range from simple Ogg/Vorbis playback, audio/video streaming to complex audio (mixing) and video (non-linear editing) processing. Applications can take advantage of advances in codec and filter technology transparently. Developers can add new codecs and filters by writing a simple plugin with a clean, generic interface. | Used by **gst-switch**, **speakertrack** and **flumotion**. | | ||
| | **eventstreamer** | [(C)](https://github.com/lukejohnosmahi/eventstreamr) | EventStreamer is a single and multi room audio visual stream management. It is designed to scale down for a single monthly LUG talk and scale up for conferences such as linux.conf.au. The base OS image forms the foundation for eventstreamr. The goals are simple: every host has the base image installed, the base image includes all software required to perform all roles and simple setup script to go from imaged to production. | Used by **linux.conf.au 2014** and **[PLUG](http://plug.org.au)**. | |
