Here is another edition of the stereoscopic metadata.
This version follows most of the comments received: there is a bitfield for
binary information like size (full/half), sampling and other data, and an enum
for the most important part, the stereo type. Overall I used a struct so there
could be space for implementing future things, like number of views and depth
map presence.
For now this metadata applies only to frame metadata and it can carry over
stereo information to/from h264 and mpeg2, but in the future it is possible to
extend this to packets also, in order to wrap matroska and wmv stereo
inforation too.
Cheers,
Vittorio

avframe: add codec-independent stereoscopic metadata
h264: parse frame packing arrangement SEI messages and save relevant
stereo3d information
libx264: set frame packing information when relevant metadata is
found
mpeg2dec: parse frame packing arrangment user_data and save relevant
stereo3d information
mpeg2enc: set frame packing information when relevant metadata is
found
