This bug affects the encoding of videos provided as mpeg streams to an -ovc other than copy. The following command line fails without indications of an error with the latest CVS. Encoding of the same type of files worked flawlessly with the Version of last week.:

./mencoder -v -v bug20050323.01.mpg -o bug.out.avi -nosound -ovc lavc

The full output of the command is in the accompagning log dump. Here the last few lines:

vo_debug: query(Mpeg PES) returned 0x0 (i=0) 
The selected video_out device is incompatible with this codec.
VDecoder init failed :(
Opening video decoder: [libmpeg2] MPEG 1/2 Video decoder libmpeg2-v0.4.0b
