 |
|
Hi, h264, aac, m4a does not work in firefox.
When I go to to https://www.youtube.com/html5
it says H.264 and MSE & H.264 is not supported.
Spotify with m4a sound files does not work too.
I already tried to do a new install of firefox and using a fresh profile and switching to hardware acceleration.
The firefox plugins widevine and openh264 are installed and activated.
This codecs work in my videoplayer mpv!
Please help me.
USE Flags media-video/ffmpeg
and virtual/ffmpeg
and www-client/firefox:

Error Message in Firefox Console:
| Code: | | The video on this page can’t be played. Your system may not have the required video codecs for: audio/mp4; codecs="mp4a.40.2" |
emerge --info
https://pastebin.com/rHUAE5Xr
firefox about:support output

ffmpeg is the only libavcodec:
| Code: | $ ls /usr/lib64 | grep codec.so
libavcodec.so
libavcodec.so.58
libavcodec.so.58.9.100
$equery f ffmpeg | grep codec.so
/usr/lib64/libavcodec.so
/usr/lib64/libavcodec.so.58
/usr/lib64/libavcodec.so.58.9.100

I think here's your problem. The newest FFMPEG only works with mpv-0.28, but breaks compability with every other program. Try emerging ffmpeg with 55.57.57 compatible ABI, and maybe re-emerge firefox. |

Thank you very much! That worked!
Do I have to live without the git version of mpv ? Or is there a way to have ffmpeg-9999 and ffmpeg-3.4.1 installed at the same time ? |

| Well in theory they are slotted so they should be available to be installed at the same time. But in practice, I really dont know... |
