[ATrpms-users] ffmpeg audio problem with mythstreamtv

[Thomas Börkel]

HI!

I've installed mythstreamtv into MythWeb 0.19 and it works basically.

But I do not get audio, because of this error from vlc:
ffmpeg encoder error: cannot find encoder MPEG Audio layer 1/2/3

I've looked at the .spec file for ffmpeg, and MPEG audio seems to be
enabled (--enable-mp3lame), although the README from mythstreamtv uses
--with-ffmpeg-mp3lame.

Using these packages in FC3:
lame 3.96.1-10.rhfc3.at
ffmpeg 0.4.9-14_cvs20060301.rhfc3.at
videolan-client 0.8.1-2.1.fc3.fr

Any hints?

Thanks!

Thomas

I'd first check whether vlc w/o myth/mythstreamtv etc. works with MPEG
Audio layer 1/2/3.

It does not, same error:

That is why I suspected, that the ffmpeg package does have a problem.

Apparently it works, if I use mpga instead of mp3 as audio codec.

Or vlc, since ffmpeg is used quite extensively at other bits at
ATrpms. Try rebuilding vlc.
