[MPlayer-dev-eng] [PATCH]Add field_dominance to bobdeint

[Carl Eugen Hoyos]

Hi!

http://samples.mplayerhq.hu/MPEG-VOB/interlaced/V.VOB claims to be interlaced 
with bottom field first, but is actually top field first. Attached patch 
allows it to play correctly with -vo xvmc:bobdeint by adding field_dominance:
mplayer V.VOB -vc ffmpeg12mc -vo xvmc:bobdeint:field_dominance=0

 Very simple deinterlacer.
 Might not look better than \-vf tfields=1,
 but it is the only deinterlacer for xvmc (default: nobobdeint).
+.IPs field_dominance=<-1\-1>
+Operates like tfields.
 .IPs (no)queue
 Queue frames for display to allow more parallel work of the video hardware.
 May add a small (not noticeable) constant A/V desync (default: noqueue).

 Sehr einfacher Deinterlacer.
 Sieht möglicherweise nicht besser als \-vf tfields=1 aus, ist aber
 der einzige Deinterlacer, der mit xvmc funktioniert (Standard: nobobdeint).

+Arbeitet wie tfields.
 .IPs (no)queue
 Frames werden in einer Queue angeordnet, um der Videohardware weitergehendes
 paralleles Arbeiten zu ermöglichen.
