[FFmpeg-user] ffmpeg producing garbled output / problems

Fri Dec 21 19:33:02 CET 2012

Sorry!

I had to snip some of the output for creating movie.mpg because of repeating "packet too large" and "buffer underflow" messages.

$ ffmpeg -ar 48000 -f s16le -ac 2 -i /dev/zero -loop 1 -i psa.tif -t 15 -r 29.97 -q:v 1 -c:v mpeg2video -c:a mp2 -vf "fade=in:0:30, fade=out:420:30" psa.mpg
