i have what is supposedly a short mjpeg that i downloaded from one of my IP
cameras.
i want to split up the frames into individual jpgs. lavtrans gives:
$> lavtrans -o image%05d.jpg -f i 20071203_205830.mjpeg
Unable to identify file (not a supported format - avi, quicktime).
**ERROR: [lavtrans] Error opening 20071203_205830.mjpeg
lavplay does the same.
i just want to split up the frames so i can digi-zoom/crop and "enhance"
each frame (it's only about 120 frames)
i need this to be automated as it's going to happen every 60 mins or so
do i have to cram that into an avi container?
mplayer seems to think it's in one already:
here is the output from mplayer which plays the file fine:
