I'm having the same issue as this recent thread:
splitting an MJPEG to a series of JPEGs
http://sourceforge.net/mailarchive/message.php?msg_id=13190010
I have a Canon camera with MJPEG AVIs and when I ran the command:
$ mkdir pics; lavtrans +n -o pics/t%05d.jpg -f i mvi_1434.avi
I get jpegs images that I cannot view (with display, gqview, firefox, gimp, etc).
Apparently because there is no huffman table or it is empty?
Christopher mentioned:
So the approach I end up using is to first translate the MJPEG to
a YUV stream, transform these to PNMs, then transform the PNMs to
JPEGs:
bash% lav2yuv +n MVI_1704.AVI | y4mtoppm | pnmsplit - image%d.pnm
This is cludgy (but thanks Chris!) but is there a quick way to get these pnm's
into jpg format again that are actually viewable? An good way to bath process
this on the CLI besides a for loop and ppntojpeg?
Thanks - Brian
