As long as there is only one codec out of many many more which can't
be decoded normal is correct. mocp is usable!

Did you tested this with mocp as well?

Just for clarification:
avplay is out of the libav-tools and has therefore no influence to
the function of moc. But avplay uses the same libraries as the
moc-ffmpeg-plugin:
$ ldd `which avplay` | grep av
libavdevice.so.54 => /usr/lib/x86_64-linux-gnu/libavdevice.so.54
(0x00007f4ebe0c3000)
libavfilter.so.4 => /usr/lib/x86_64-linux-gnu/libavfilter.so.4
(0x00007f4ebde74000)
libavformat.so.55 => /usr/lib/x86_64-linux-gnu/libavformat.so.55
(0x00007f4ebdb3f000)
libavresample.so.1 => /usr/lib/x86_64-linux-gnu/libavresample.so.1
(0x00007f4ebd920000)
libavcodec.so.55 => /usr/lib/x86_64-linux-gnu/libavcodec.so.55
(0x00007f4ebca43000)
libavutil.so.53 => /usr/lib/x86_64-linux-gnu/libavutil.so.53
(0x00007f4ebc5d0000)
$ ldd /usr/lib/moc/decoder_plugins/libffmpeg_decoder.so | grep libav
libavutil.so.53 => /usr/lib/x86_64-linux-gnu/libavutil.so.53
(0x00007f7ca3e83000)
libavcodec.so.55 => /usr/lib/x86_64-linux-gnu/libavcodec.so.55
(0x00007f7ca2fa6000)
libavformat.so.55 => /usr/lib/x86_64-linux-gnu/libavformat.so.55
(0x00007f7ca2c71000)
So from that point of view the failure of playing your codec from a
mp4 container grounds to the responsible libraries provided by the
libav*.so libraries.

You pointed out a bug in the libavcodecs, though.

We are talking about an up to date sіd/testing here. We dont't support older
versions nor stable ones (only in security cases, though)

Not directly. I explained the relation to libav above.

A mix of DMO packages and Debian distri is very bad and not
supported. You find everything you need in our sid distribution.

Before we reassign this bug to libav please show us the output of:
$ ldd `which moc`
$ ldd /usr/lib/moc/decoder_plugins/libffmpeg_decoder.so | grep libav
Move all mp4 containers to a sepearte directory and start mocp to
play mp3's, flac's, ogg's, opus', aac's, spx's, m4a's, wav's, sid's,
wma's ..... just everthing you have available. Does it work?
