Don't escape the codec_data, it breaks some streams (but likely also fixes
others). It's better to leave it as is, like most other players do.
See #608332
Use format field in the pad caps to differentiate VC-1 from WMV3.
Fix a typo in the caps creation and parsing - the field is called
'format' - not 'fourcc'
Add a dodgy hack to populate the extradata size field
(first byte) when it is 0 - as it seems to be for some (Matroska)
test files.
When the video caps aren't fixed yet, make sure we return the most
precise set of caps. It seems a regression was introduced in cc082f,
causing restricted caps to never be used if the context == NULL
None of the restricted caps generation uses the context, so no need to
check whether the context.
Fixes bug #578160.
We don't need to set a default frame_size, ffmpeg has set this value to 0 to
inform us that there is a fixed relation between the amount of input samples
and output samples. Now we only need to implement handling that fact.
Without a frame_size configured in the context, the ffmpeg encoders do nothing.
Since the G726 does not configure a size itself, we set ourselves a frame_size
that corresponds to 20ms of audio, which is a reasonable default.
AVOutputFormat does *NOT* contain the full list of codecs a muxer can handle,
but does contain the recommended audio and video codecs. Therefore we use that
information to expose more muxers, until AVOutputFormat contains a list of
*ALL* compatible codecs.
For a given AVCodec, when the sample_fmts field is non-NULL, that means that
that codec can only handle a specific set of SampleFormat.
With this patch, we now look for its presence and create the proper pad template
caps.

Original commit message from CVS:

ffmpeg audio decoders can now do up to 6 channels... and actually
expose it properly. Don't expect any channel mapping though.
Original commit message from CVS:
* ext/ffmpeg/gstffmpegcodecmap.c: (gst_ffmpeg_caps_to_pixfmt):

Fail negotiation if pixfmt cannot be determined from input caps.
Prevent segfault accessing non-existant coded_frame, provide some
warning debug output instead.
