Running: docker run -v SampleVideos:/home openvisualcloud/xeon-ubuntu1804-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 -umv 0 -y test.mp4"

Printout banner: SVT [config]: tileColumnCount / tileRowCount / tileSliceMode / Constraint MV : 1 / 1 / 0 / 0

docker run -v SampleVideos:/home openvisualcloud/xeon-ubuntu1804-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 -umv 1 -y test.mp4"

Printout banner is the same: SVT [config]: tileColumnCount / tileRowCount / tileSliceMode / Constraint MV : 1 / 1 / 0 / 0

With umv 0 and umv 1 the banner prints the same UMV mode

@raztexel - Can you confirm you rebuilt the SVT-HEVC plugin for ffmpeg using the updated patch file?

raztexel commented 4 years ago

I have just used the docker command. I haven’t built SVT-HEVC.

This is what I have run:

docker run -v SampleVideos:/home openvisualcloud/xeon-ubuntu1804-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 -umv 1 -y test.mp4"

Does docker openvisualcloud/xeon-ubuntu1804-media-ffmpeg supports tiling at all or should I use different docker to work with "umv 1" ?

tianjunwork commented 4 years ago

Hi @raztexel , OpenVisualCloud/Dockerfiles only builds the latest release tag. https://github.com/OpenVisualCloud/Dockerfiles/blob/master/doc/svt.md#Evaluate-SVT - umv in ffmpeg is in the master which is after 1.4.3 release tag. Tiling feature is in 1.4.3 release.

Hi @raztexel , do you need any more help about -umv parameter? If not, could you close? Thank you.
