You can now make stop frame animations with ffmpeg native on the phone
See test10frame.m4v above (drunknbass of #iphone provided the frames to test this!)
So, assume you have a bunch of pictures that you have taken on your
iPhone, in some sort of sequence:
iPhone:~/Media root# ls -C1 /var/mobile/Media/DCIM/100APPLE/IMG_000*.JPG
/var/mobile/Media/DCIM/100APPLE/IMG_0001.JPG
/var/mobile/Media/DCIM/100APPLE/IMG_0002.JPG
/var/mobile/Media/DCIM/100APPLE/IMG_0003.JPG
/var/mobile/Media/DCIM/100APPLE/IMG_0004.JPG
/var/mobile/Media/DCIM/100APPLE/IMG_0005.JPG
You can use this simple one liner:
iPhone:~/Media root# ../ffmpeg -f image2 -i \
/var/mobile/Media/DCIM/100APPLE/IMG_000%d.JPG -s 320x240 -f mp4 ./test.m4v
Input #0, image2, from '/var/mobile/Media/DCIM/100APPLE/IMG_000%d.JPG':
Duration: 00:00:00.3, start: 0.000000, bitrate: N/A
Stream #0.0: Video: mjpeg, yuvj420p, 1600x1200, 25.00 fps(r)
PIX_FMT_YUV420P will be used as an intermediate format for rescaling
Output #0, mp4, to './test.m4v':
Stream #0.0: Video: mpeg4, yuv420p, 320x240, q=2-31, 200 kb/s, 25.00 fps(c)
Stream mapping:
Stream #0.0 -> #0.0
Press [q] to stop encoding
frame= 8 fps= 1 q=9.4 Lsize= 105kB time=0.3 bitrate=2692.2kbits/s
video:104kB audio:0kB global headers:0kB muxing overhead 0.684381%
Then you can play it on the phone:
iPhone:~/Media root# ../bin/playaudio test.m4v
TADA Instant movie...! So I wonder... this could be useful I guess :))
The following exercise is left to the reader, you will need erica's pic snap tools for this:
iPhone:~/Media root# cat snapper.sh
#!/bin/bash
i=0
max=10
while [ "$i" -lt "$max" ]
do
../bin/picSnap $i.jpg
echo -n "$i "
let "i += 1"
done
iPhone:~/Media root# ./snapper.sh
0 1 2 3 4 5 6 7 8 9
iPhone:~/Media root# ../ffmpeg -f image2 -i %d.jpg -s 320x240 -f mp4 ./test.m4v
Added destructions for Erica that DIVX using the native ffmpeg above on the iPhone is ok
(slow but seems to work...):

Now we get to use Erica's PLAYAUDIO (which does video... it would not work on the AVI,
but now it has been through ffmpeg) we are all set:

SUCCESS!
Added iTubby :) simple one liner to fetch flv from youtube, and drop it on your phone
Extract itubby to /var/root/itubby, this one has the correct wget, a copy of sed,
and a trimmed down ffmpeg with just the faac stuff we need to make this work:

Updates to allow shockwave to mp4
Grab ffmpeg.new.gz, this one can now deal with youtube video and convert to mp4. It also has a
bunch of other stuff in it:

For Erica
We can now convert amrs to mp3, or wav:
