Hi Dave, thank you for looking into the issue! On Sun, 17 Jan 2021, Dave Plater wrote:
I'm not sure which codec is involved in "Microsoft Teams"
Unfortunately I'm not sure either. I get no relevant errors on the terminal or on the javascript console. But I have seen Teams video calls working in Chromium in the recent past (a month ago maybe). I suspect the codec is MPEG-4 ASP because I get "not supported" when I visit on html5test.com: MPEG-4 ASP support No ✘ H.264 support Yes ✔ H.265 support No ✘ Ogg Theora support Yes ✔ WebM with VP8 support Yes ✔ WebM with VP9 support Yes ✔ Is anybody getting different results on Chromium?
but the summery for chromium-ffmpeg-extra says "Extra ffmpeg codecs for browsers based on Chromium" the actual ffmpeg libraries libavcodec libavformat etc are required by chromium itself. If you know the specific codec you can find out what your ffmpeg provides with "ffmpeg -codecs"
I see a codec listed that can handle MPEG-4 AVC: DEV.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders: h264 h264_v4l2m2m h264_qsv h264_cuvid ) (encoders: libx264 libx264rgb h264_nvenc h264_qsv h264_v4l2m2m h264_vaapi nvenc nvenc_h264 )
if you don't have the packman versions of libavcodec, the actual package that Tubleweed chromium uses is libavcodec58_91, then this may be your problem.
I just verified that I have it installed from Packman repo, here is what `zypper search -v` shows: i+ | libavcodec58_91 | package | 4.3.1-9.7 | x86_64 | Packman Repository What remains as a mystery to me, is how the library /usr/lib64/chromium-ffmpeg-extra/libffmpeg.so gets loaded by Chromium or ffmpeg. I have grep'ed or strace'd my whole system with no results. That path is not listed anywhere. I am starting to believe that this package is not working any longer.
