[MPlayer-users] Getting a list of Demuxer and Decoders and deinterlaced video probing.

[Jason Brower]

I am building a webapp that needs to extract data from video files found
on rss feeds. (Miroguide.com) But I need a list of expected demuxer and
decoders that are user by mplayer.
"-identify" gets me the one used but not a list for me.
Where can I get that list?
Additionally, is there a way to find out if a video is deinterlaced or
not?
Perhaps someone could just throw it here.
Highest Regards,
