No, it doesn't ... $ wf-recorder -c libvpx-vp9 -C opus -f recording.mkv $ file recording.mkv recording.mkv: Matroska data ... but it still takes a looong time to build the index. On VP9: Maybe I'll just settle on libvpx-vp9 and patch the source so that on SIGINT it prints "SIGINT received: please wait for index building". That's the easiest fix - but maybe we'll get 'oh fedora is soooo sloooow' whinges. On VP8: alabastr gave me the hint that using "--muxer webm" would make v8 work - and it terminates quickly, so this is another possibility. The only question is - is it naf to have a webm in an mp4? Also, is it too naf to patch the source to force '--muxer webm' if codec is detected as libvpx? $ wf-recorder -c libvpx -m webm Output file "recording.mp4" exists. Overwrite? Y/n: y selected region 0,0 0x0 Using video filter: null [libvpx @ 0x7f6d40001e80] v1.12.0 [libvpx @ 0x7f6d40001e80] Neither bitrate nor constrained quality specified, using default CRF of 32 and bitrate of 256kbit/sec Output #0, webm, to 'recording.mp4': Stream #0:0: Video: vp8, yuv420p(pc), 1920x1080 [SAR 1:1 DAR 16:9], q=2-31, 256 kb/s ^C $ file recording.mp4 recording.mp4: WebM <<<<< TOO NAF?
