In the function gst_ffmpeg_formatid_get_codecids() in the if / else if
construct the special case !strcmp (format_name, "pva") should be
handled before the generic case (plugin->audio_codec !=
AV_CODEC_ID_NONE) || (plugin->video_codec != AV_CODEC_ID_NONE)
This patch fixes the ordering.
I stumbled accorss this issue while adding a new format to
gst_ffmpeg_formatid_get_codecids()

This removes the internal interleave loop and always negotiates
the native output layout of the libav decoder. Users can use
audioconvert to interleave if necessary.
Special care has been taken to leave the encoder unaffected by
the changes in avcodecmap, since GstAudioEncoder doesn't support
the non-interleaved layout yet.

We were previously installing hardcoded properties for all
video encoders, refactor to instead use FFmpeg's AVOption API.
avvidenc still exposes a few properties related to the pass
mechanism: while the AVOption API allows specifying both passes
as flags at the same time, this is not practical in GStreamer's
context, where passes need to be run separately using a stats file.

The remaining use of CODEC_ are codec flags that has been moved into the
new codec private properties or have been deperated. Will be fixed in
later patches.

We expect it to be a int or uint, however it changed the type to a
int64_t in later versions of ffmpeg. As such it would be passed as a 64
bit value to varargs functions, while the consumer of the arguments
assumes only 32 bits. This causes crashes.

In ffmpeg this is the same as FRONT_CENTER, but we distinguish between
FRONT_CENTER and MONO in GStreamer. Add an explicit mapping for this special
case in the translations functions.

Multithreaded encoders are going to free this dummy codec data twice, e.g.
with this pipeline
gst-launch-1.0 videotestsrc num-buffers=40 ! \
videoconvert ! avenc_mjpeg ! fakesink
There exist few formats (deprecated though) used by mjpeg decoder
and encoder that maps to the same GStreamer format. To properly
pick the right format, also lookup each Codec list before accepting
the format. This fixes error when trying to use mjpeg encoder.
Note that this may results in faded colors. In fact, these special
format are meant to specify that this is full range YUV. Colorimetry
in gst-libav is not yet implemented, hence is ignored in general. So
I think it's fine to first fix the issue before addressing the missing
feature.

Remove x-xvid and x-3ivx. The last place where they were used are
in the srcpad caps of the decoder but since the decoder will never
actually output those caps we can safely remove them.
Always enable 4MV flag for MPEG4
Pare the profile property and enable more features for advanced-simple
profile.
video/x-xvid is advanced-simple profile so enable more features.
We now also support encoding of video/x-xvid so add this to the caps.

The VC-1 decoder should handle that. Before avdec_wmv3 handled
it, but then we added format=WMV3 to its sink pad template
caps, at which point nothing handled WMVA any longer.
