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

ffmpeg: unrecognized option '-loglevel'
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.
