[MPlayer-users] Strange avi generating "OBMC not supported" warnings

[Vladimir Mosgalin]

I've got one strange .avi. It plays well with mplayer using ffmpeg, but
there are a lot of warnings while playback. Two or three times a second
i get

	OBMC not supported (very likely buggy encoder)

There is message
	looks like this file was encoded with (divx4/(old)xvid/opendivx) ->
	forcing low_delay flag
after ffmpeg initialization.

Apart from this, everything is fine, but this bothers much.  I decided
to try other decoders.  I've got almost every possible mpeg4/divx
installed (except xvid). They all work fine with other avi files.

I ran mplayer with options "-vo null -nosound -vc XXX".

-vc odivx/divx4 - using divx4linux-20020418.
This is only codec that works apart from ffmpeg. It does not write
any warnings and decodes well.

-vc divx4vfw - using divx.dll
Forced video codec: divx4vfw
Opening video decoder: [vfw] Win32/VfW video codecs
Loading codec DLL: 'divx.dll'
External func psikey.dll:9
"mplayer crashed with sig11 in module init_video_codec"

-vc divxds - using divx_c32.ax
...
Forced video codec: divxds

Не могу найти кодек для видео формата 0x58564944 !
...
(sorry for russian, the message is
"cannot open codec for video format 0x58564944")

-vc divx - using divxc32.dll
same here. "cannot open codec for video format 0x58564944"

-vc mpeg4 - using mpg4c32.dll
same here.

-vc mpeg4ds - using mpg4ds32.ax
and here.

First 1M of this file shows the problem, so i can upload it.
