[Mplayer-cvslog] CVS: main/libmpcodecs vd_ffmpeg.c,1.35,1.36

[Atmosfear]

Update of /cvsroot/mplayer/main/libmpcodecs
In directory mail:/var/tmp.root/cvs-serv22271/libmpcodecs

Modified Files:
	vd_ffmpeg.c 
Log Message:
Generate ffmpeg compatible vstats_<time>.log, when -lavdopts vstats is specified.
Data in my tests was 100% the same, only type= is currently missing, as avctx->key_frame
isn't set on decoding and I dunno where to get that info from mplayer-core.
