SVT-AV1 : After encoding the video seeking is very bad in any video player (even HTML5)
18 juin 2020, par Viktor Machniki am using SVT-AV1 and FFMPEG to encode Videos into the AV1 video and opus audio codec (.webm), it works fine, except that the video seeking do not work really (extremly bad). When i seek, the CPU useage jumps up and it takes up to minutes until the seeking process finishes.



Here is how i encode the videos :



- 

- Convert any video into yuv :
ffmpeg -i -preset veryslow -level 6.2 .yuv
- First AV1 run
svt-av1 -i '.yuv' -w -h --fps --rc 0 -q 30 --preset 8 -b '.\output1.ivf' --output-stat-file '.\stat_file.stat' --keyint 1 --enable-restoration-filtering 1
- Second AV1 run
svt-av1 -i '.yuv' -w -h --fps --rc 0 -q 30 --preset 3 -b '.\output.ivf' --input-stat-file '.\stat_file.stat' --keyint 1 --enable-restoration-filtering 1
- Get source video audio in opus codec
ffmpeg -i -c:a libopus -vn -preset veryslow -level 6.2 output.ogg
- Get final .webm video
ffmpeg -i output.ivf -i output.ogg -c copy output.webm













I have allready tryed to play with the —keyin option, also just letting it away and use the encoder default, but the results are always the same. (
--keyin 1
seems to work better than without this option, but also very very bad)


What am i doing wrong ?



Extras : I am using Windows 10 with downloaded version of SVT-AV1 and FFMPEG (I just renamed the SVT-AV1 Encoder .exe file to be
svt-av1.exe
). Used CPU is Ryzen 9 3900X
