New submission from dirtyHippy <[email protected]>:
I am trying to combine a large number of jpegs into a single mjpeg video. I am
using SVN-r25150 on OSX 10.6. ffmpeg segfauls after a frame or two. The
command I am using to launch ffmpeg is:
ffmpeg -i %d.jpg -f mjpeg tl.mjpeg
verbose output is as follows:
ffmpeg -v 9 -loglevel 99 -i %d.jpg
