avviddec: Map any stereo3D info to multiview modes

Map any libav Stereo3D side data to GStreamer multiview
mode / flags for playback.

Here's the decoder part (tested only with H.264)

Shouldn't this come with code that checks if the multiview mode/flags have changed (per frame) and renegotiate then? Like we do for interlaced for example

Good point.

In case it's not clear, there's also a patch to write for the demuxers and muxers to map AVPacket side-data to GStreamer caps too.

What's the status here?

I didn't get back to working on the patches yet, so no change - the viddec patch needs updating for renegotiation, and we need some patches for the demuxers/muxers case.

I'm not sure it's worth writing the code mapping input/output to/from demuxers/muxers - we don't map or encourage the use of any of the libav muxers that support signalling of multiview information anyway (mp4, mkv, asf)
