audacious cannot play AMR files with its ffmpeg plugin (ffmpeg supports AMR from 0.8)

[Roman Polach]

audacious 3.3.4-1 cannot play AMR files with its ffmpeg plugin
(included in audacious-plugins-3.3.4-1ubuntu1)
and libavcodec53 6:0.8.6-1ubuntu2 and ffmpeg 6:0.8.6-1ubuntu2.

That is strange, because ffmpeg supports both AMR-wb and AMR-nb
from ancient release 0.8.

[Daniel Letzeisen (dtl131)]

The AMR codecs are included in the libavcodec53-extra package (which was split off because of licensing reasons). Please confirm that you can play the files with that package installed. If not, I will investigate more.

Marking 'Incomplete' until you respond..

[Roman Polach (rpolach)]

even with libavcodec-extra-53 6:0.8.6ubuntu2 installed
it still shows the same error message:
No decoder found for file:///home/roman/amr_example.amr.

[Daniel Letzeisen (dtl131)]

I could not reproduce it. My example file:

[Daniel Letzeisen (dtl131)]

Hmm. Maybe you need libavformat-extra-53 as well?

[Roman Polach (rpolach)]

I have 3 amr-nb samples and one of them is played ok in audacious.
Two of them don't play.

I do not see any significant differences between mediai...

[Roman Polach (rpolach)]

attaching those 2 samples which do not play in audacious...

Note: They play ok in mplayer2.

[Roman Polach (rpolach)]

and this one plays OK in audacious:

[Daniel Letzeisen (dtl131)]

I would try playing the files with avplay, to see if it is audacious, or a more general ffmpeg/libav issue:
avplay <file>

[Daniel Letzeisen (dtl131)]

Okay, I tried the experiment and the files work fine in avplay, but not with audacious.

[Daniel Letzeisen (dtl131)]

In Debian, using audacious 3.5.x built from git (and ffmpeg as opposed to libav), all of the files play okay.
