 in this example I tried to transcode a mkv with h264 and dca to mp4 and
 ac3. The commandline was:

 ffmpeg -i Excalibur\ 1981.mkv -sameq -vcodec mpeg4 -pass 1 -threads 4 -b
 10000000 -an -f mp4 -y /dev/nul

 the next step would have been:

 ffmpeg -i Excalibur\ 1981.mkv -sameq -vcodec mpeg4 -pass 2 -threads 4 -b
 10000000 -acodec ac3 -ab 384000 -f mp4 Excalibur.mp4

 after some procerssing I got the following error:

 av_interleaved_write_frame(): Error while opening file
 bitrate=12810.9kbits/s

 the output you asked for is here:

 #ffmpeg -v 9 -loglevel 99 -i Excalibur\ 1981.mkv

 This used to work without any problems until about a month ago, now it
 fails reliably. sometimes in first pass, sometimes in second, but it will
 fail.

 OS is Ubuntu Lucid 10.04.3
