I was hoping I could take pics/video with my Canon S3 and Casio Z120, pop the SD in the N800 and review. Stills are fine, but I haven't been able to watch any AVIs successfully. Sound is there, but picture is a garbled still. Cameras create 640x480 30fps AVIs that play fine on a PC. Anyone care to suggest if this should work? I'm trying mplayer 1.0rc1-maemo.6 to no avail. Internal Media Player app fails with 'File format not supported'.
thanks, Clive

Good point about the camera videos. I assume they are in mjpeg format.

You should be able to convert them with media converter for offline viewing, but that's not very nice for on the road checking.

So, maybe mplayer could help even though it's not yet able to view them:

Seems like FFMPEG would support it. I wonder how much work would it be to add that support to mplayer. Serge?

N800 garbled picture problem should be already fixed since version 1.0rc1-maemo.7
But according to reports from N800 owners, MPlayer performance is still far from optimal on N800 (video output driver issues). Anyway, you can give it a try.

VidConvert would help whilst on the move, of course.

Try running mplayer with the -nosound option. Mplayer probably can't keep up the video playback demand of those videos so it drops frames to keep the audio playing. If you're using gmplauncher let a video play to the end so you get the benchmark results.

If I can figure out how to turn that option on, I will give it a go.
I'm not talking about dropped frames - if I saw even 5fps I would be happy. There is no motion throughout the entire clip. ie. 100% dropped frames.

Yes, mplayer should be able to play the videos at at least 5 fps, but it can't. I believe it is a problem with the frame skipping code. Playing without the sound, mplayer managed about 10 fps on my test file. Frames were not skipped, so the playing was about 1/3 normal speed. The -nosound option is added to the command line when mplayer is started. If you don't have xterm, install it and run one of the following.


Code:
replace 93-01.avi with the name of your video

to test the decoding speed:
mplayer /media/mmc1/93-01.avi    -benchmark -nosound -endpos 10

to play the video only:
mplayer /media/mmc1/93-01.avi    -nosound
