You can tweak the bit rate or use vbr instead, check out the ffmpeg codec docs So an encode would be ffmpeg -i infile.webm -vcodec libvpx-vp9 -crf 20 -acodec libopus -abitrate 128k -f matroska outfile.webm Sorry didn’t notice you asked about opus not vorbis, libopus is available in packman’s build, a change from vorbis to opus is simple, just change the encoding library to libopus Webm is mkv with a different extension and a limited codec (only vp8/9 for video and vorbis for audio)Īs I said the oss version of ffmpeg will output vpx compression but it will only accept uncompressed or vpx video you need packman’s version for a full working ffmpegĭo you have packman,post your repo list zypper lr -d Then you need to do something like ffmpeg -i infile.webm -vcodec libvpx-vp9 -crf 20 -acodec libvorbis -abitrate 128k -f matroska outfile.webm First off the ffmpeg from the oss repo is extremely limited but it should output to vp8/9 you should get it from packman
