Description
avctx->draw_horiz_band seems to be called sometimes with a NULL data pointer. This cause MPlayer to flood stderr with the following message:

See libavcodec/mpegvideo.c:ff_draw_horiz_band() where avctx->draw_horiz_band is called with src->data[0] being NULL.
I don't know which one is right here (FFmpeg or MPlayer), but something should be fixed.
matrixbench_mpeg2.mpg is available here: http://samples.ffmpeg.org/benchmark/testsuite1/matrixbench_mpeg2.mpg
I don't know if this is a regression.
Note @Reimar: I put you in copy since you're likely interested in that issue and might want to comment on it. Feel free to remove yourself from the Cc.

For some reason the MPlayer version info was not updated.

Replying to cehoyos:

Sorry it seems I forgot to say that you need to seek.

Replying to cehoyos:
Not reproducible with -vo vdpau, definitely a regression.
The message in MPlayer is fairly recent AFAIK, so the regression might have been present (as a crash) previously. If it's a regression in FFmpeg, I would guess it's from around TEP period.

I can't reproduce anymore, so closing.
Any idea what commit might have fixed it?
