The selected video_out device is incompatible with this codec.
Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.

Compiler did not align stack variables. Libavcodec has been miscompiled
and may be very slow or crash. This is not a bug in libavcodec,
but in the compiler. You may try recompiling using gcc >= 4.2.
Do not report crashes to FFmpeg developers.

FATAL: Could not initialize video filters (-vf) or video output (-vo).


this is why i wanted the scale filter inserted at the end of
the filter chain automatically. why do we output a series of unhelpful
messages?

mplayer unnamed-002.vob -nosound -vo gl -vf yadif,scale
seems to work.
