FFmpeg is a set of open source tools for audio and video processing, such as creating, converting/transcoding, and publishing media content.
The FFmpeg docker images are compiled with the following audio and video codecs:
Codec | Version | Codec | Version |
---|---|---|---|
fdk-acc | 0.1.6 | x265 | 2.9 |
mp3lame | 3.100 | vpx | 1.7.0 |
opus | 1.2.1 | dav1d | 0.5.2 |
ogg | 1.3.3 | SVT-HEVC | v1.4.3 |
vorbis | 1.3.6 | SVT-AV1 | v0.8.4 |
x264 | stable | SVT-VP9* | v0.2.0 |
* SVT-VP9 encoder app only. SVT-VP9 not yet available as a FFmpeg plugin.
The FFmpeg builds included the following patches for feature enhancement, better performance or bug fixes:
Patch | Description |
---|---|
11625 | Enhance 1:N transcoding performance. |
H.265 FLV | Support H.265 in FLV for RTMP streaming. |
ANALYTICS | Enables FFmpeg analytics pipeline with the elementary inference features. |
SVT-HEVC | Enable FFmpeg SVT-HEVC plugin |
SVT-AV1 | Enable FFmpeg SVT-AV1 plugin |
In GPU images, the FFmpeg docker images are accelerated through VAAPI
and/or qsv
(Intel® Media SDK). Note that VAAPI
or qsv
requires special setup for X11 authentication. Please see each platform README for setup details.
- Transcode raw yuv420 content to SVT-HEVC and mp4:
ffmpeg -f rawvideo -vcodec rawvideo -s 320x240 -r 30 -pix_fmt yuv420p -i test.yuv -c:v libsvt_hevc -y test.mp4
- 1:N Transcoding:
ffmpeg -i input.h264 -vf "scale=1280:720" -pix_fmt nv12 -f null /dev/null -vf "scale=720:480" -pix_fmt nv12 -f null /dev/null -abr_pipeline
- Encoding/decoding with
VAAPI
:
ffmpeg -y -vaapi_device /dev/dri/renderD128 -f rawvideo -video_size 320x240 -r 30 -i test.yuv -vf 'format=nv12, hwupload' -c:v h264_vaapi -y test.mp4
ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -i test.mp4 -f null /dev/null
- Encoding/decoding with
qsv
(Intel Media SDK):
ffmpeg -y -init_hw_device qsv=hw -filter_hw_device hw -f rawvideo -pix_fmt yuv420p -s:v 320x240 -i test.yuv -vf hwupload=extra_hw_frames=64,format=qsv -c:v h264_qsv -b:v 5M test.mp4
ffmpeg -hwaccel qsv -c:v h264_qsv -i test.mp4 -f null /dev/null
- Face detection and emotion identification, save metadata to json format:
ffmpeg -i ~/Videos/xxx.mp4 -vf detect=model=./face-detection-adas-0001/FP32/face-detection-adas-0001.xml:device=CPU, \
classify=model=./emotions_recognition/emotions-recognition-retail-0003.xml:model_proc=emotions-recognition-retail-0003.json:device=CPU, \
metaconvert=converter=json:method=all \
-an -f metapublish -output_format batch -y emotion-meta.json
- Object Detection:
ffmpeg -i ~/Videos/xxx.mp4 -vf detect=model=./mobilenet-ssd.xml:model_proc=mobilenet-ssd.json:device=CPU -an -f null /dev/null
- Face detection and reidentification:
ffmpeg -i ~/Videos/xxx.mp4 -vf "detect=model=./face-detection-retail-0004.xml:device=CPU, \
classify=model=./face-reidentification-retail-0095.xml:model_proc=./face-reidentification-retail-0095.json:device=CPU,identify=gallery=./gallery, \
metaconvert=converter=json:method=all" \
-f metapublish -output_format batch -y /tmp/face-identify.json
- Car attribute recognition:
ffmpeg -i ~/Videos/xxx.mp4 -vf "detect=model=vehicle-detection-adas-0002.xml:model_proc=vehicle-detection-adas-0002.json:device=CPU, \
classify=model=vehicle-attributes-recognition-barrier-0039.xml:model_proc=vehicle-attributes-recognition-barrier-0039.json:device=CPU" -an -f null /dev/null
- Car-Bike-Person detection:
ffmpeg -i ~/Videos/xxx.mp4 -vf "detect=model=person-vehicle-bike-detection-crossroad-0078.xml:model_proc=person-vehicle-bike-detection-crossroad-0078.json:device=CPU" -an -f null /dev/null
- GPU decode with
VAAPI
+ detection:
ffmpeg -flags unaligned -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device /dev/dri/renderD128 \
-i $STREAM -vf "detect=model=$DETECTION_MODEL:device=$DEVICE" -an -f null - \
