Scalable Video Technology (SVT) is a software-based video coding technology that is highly optimized for Intel® Xeon® Scalable processors and Intel® Xeon® D processors. SVT provides flexible high-performance software encoder core libraries for media and visual cloud developers.
SVT modules
SVT Images get built with following SVT transcoders
| Module | Version | Comment |
|---|---|---|
| SVT-HEVC | v1.5.1 | HEVC-compliant encoder library core that achieves excellent density-quality tradeoffs |
| SVT-AV1 | v0.8.7 | AV1 Compliant encoder library for VOD and Live encoding / transcoding video applications |
| SVT-VP9 | v0.2.2 | VP9 Compliant encoder library for VOD and Live encoding / transcoding video applications |
Evaluate SVT
The easiest way to evalute SVT is through the latest release on Docker Hub, log onto a Linux PC with docker engine installed, execute “docker run <_image_> <_command_>" to try various SVT related functions. Refer to below examples:
- SVT HEVC encoder:
sudo -E docker run openvisualcloud/xeon-ubuntu2004-media-svt /bin/bash -c "dd if=/dev/urandom bs=115200 count=300 of=test.yuv && SvtHevcEncApp -i test.yuv -w 320 -h 240 -b out.ivf ." - SVT AV1 encoder:
sudo -E docker run openvisualcloud/xeon-centos7-media-svt /bin/bash -c "dd if=/dev/urandom bs=115200 count=300 of=test.yuv && SvtAV1EncApp -i test.yuv -w 320 -h 240 -b out.ivf ." - SVT VP9 encoder:
sudo -E docker run openvisualcloud/xeon-ubuntu2004-media-svt /bin/bash -c "dd if=/dev/urandom bs=115200 count=300 of=test.yuv && SvtVp9EncApp -i test.yuv -w 320 -h 240 -b out.ivf ." - SVT HEVC with FFmpeg:
sudo -E docker run openvisualcloud/xeon-ubuntu2004-media-ffmpeg /bin/bash -c "dd if=/dev/urandom bs=115200 count=300 of=test.yuv && ffmpeg -f rawvideo -vcodec rawvideo -s 320x240 -r 30 -pix_fmt yuv420p -i test.yuv -c:v libsvt_hevc -y test.mp4" - SVT AV1 with FFmpeg:
sudo -E docker run openvisualcloud/xeon-centos7-media-ffmpeg /bin/bash -c "dd if=/dev/urandom bs=115200 count=300 of=test.yuv && ffmpeg -f rawvideo -vcodec rawvideo -s 320x240 -r 30 -pix_fmt yuv420p -i test.yuv -c:v libsvt_av1 -y test.mp4"
