431f3e0e6f avviddec: Only create the AVBuffer once the stride is validated 
If it is created earlier and the stride is invalid, then the frame
will be freed and it won't be possible to use it in the fallback path.
Not doing this causes a segfault because it will try to use
already freed memory.

7d3c7109ac avviddec: fix slice_offset memory leak 
In case of real videos, slice_offset is being allocated,
but the same is not being freed.

97f58baecd Switch from libav v11.4 to ffmpeg n2.7.1 
ffmpeg seems to be the one of the two forks, which is most widely used by
Linux distributions and in general. Also Google is using it for e.g. Chrome
and has engineers working on finding and fixing security issues in it.

2a445cb5f2 avauddec: Remove custom buffer allocation function 
libav always uses planar audio formats nowadays, not much use in
us trying to allocate anything here until we add support for planar

9b2c0c2dbc avviddec: libav will already copy the reordered_opaque pointer for us

broken by libav at a later time.

5b6c8ee8c9 avviddec: Negotiate based on the AVFrame information, not the context information 
The context contains the information from the latest input frame, we're
however interested in the information from the latest output frame. As we have
to negotiate for the buffer that is about to come next.

This should fix some crashes that happened when both information got out of
sync. If that happens now, we will do fallback allocation until the output
is renegotiated too.

a33a1bf6e4 avcodec: Check against codec format list 
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.

904b53ab0d Add drain() vfunc implementation that does the same as finish() 
finish() is called at EOS, drain() is called at all other times
when the decoder should be drained out. gst-libav decoder behaviour
is the same in both cases, so use the same implementation
