[MPlayer-users] 3D-Stereo video in a TS issue

[Marco Munderloh]

Hi Daniel,

if this is a AVCHD-3D camera/file, the contained video stream is MVC coded,
meaning one stream is standard h.264/AVC and the second one is coded with MVC
extension dependent on the first stream. It is not decodable alone.
ffmpeg/mplayer does not (yet) support MVC (AFAIK). However, I one wrote a
demuxer program which converts your AVCHD-3D file into MVC which is
decodable by the JM reference decoder. I can provide it
to you if it is of any use. An alternative would be this program:
http://www.3dtv.at/Products/MvcConverter/Index_de.aspx

However, you get 2 independent uncoded RAW video streams which need quite a
lot of space (we are talking of TB here).
