FFmpeg is a set of open source tools for audio and video processing, such as creating, converting/transcoding, and publishing media content.
Audio/Video Codecs:
The FFmpeg (n4.4.3) docker images are compiled with the following audio and video codecs:
| Codec | Version | Codec | Version |
|---|---|---|---|
| fdk-acc | 2.0.2 | x265 | 3.4 |
| vpx | 1.12.0 | opus | 1.3.1 |
| dav1d | 0.9.2 | ogg | 1.3.5 |
| SVT-HEVC | v1.5.1 | vorbis | 1.3.7 |
| SVT-AV1 | v1.3.0 | x264 | stable |
| SVT-VP9* | v0.3.0 |
* SVT-VP9 encoder app only. SVT-VP9 not yet available as a FFmpeg plugin.
Patches:
The FFmpeg builds included the following patches for feature enhancement, better performance or bug fixes:
| Patch | Description |
|---|---|
| 11625 | Enhance 1:N transcoding performance. |
| SVT-HEVC | Enable FFmpeg SVT-HEVC plugin |
| SVT-AV1 | Enable FFmpeg SVT-AV1 plugin |
GPU Acceleration:
In GPU images, the FFmpeg docker images are accelerated through VAAPI and/or qsv (Intel® Media SDK). For Flex Series GPUs, oneVPL is used for acceleration. Note that VAAPI or qsv requires special setup for X11 authentication. Please see each platform README for setup details.
Examples:
- 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
