Holy cripes, the video project has finally gotten started!
senab:
MPEG4 would be better than MPEG2 at low bitrates and H264 would be alot better than both of them. To be honest I don't actually think MPEG4 is that much more complex in terms of computing, H264 would be though and you'd definetly need the broadcom core on the 5G for using that.
michael.conner:
Are there any plans to get the video out on the Photo/Video models (the composite signal from the headphone jack) working in Rockbox? I mean, first things first, obviously -- but it would be really cool to be able to use Rockbox to watch video on a TV.

I'm a Linux user, and used mpeg2enc from the mjpegtools project, converting from an existing MPEG-2 file using mpeg2dec. An example command is:
mpeg2dec -t 17 -o pgmpipe < inputfile.ts | pgmtoy4m -i p -r 60000:1001 -a 16:9 | y4mscaler -O size=320x176 | yuvfps -r 30000:1001 | mpeg2enc -a 3 -f 8 -q 6 -D 10 -E -10 -K tmpgenc -4 1 -2 1 -o test-320x176.m2v
This example takes a high-definition (1280x720p) 59.94fps input file (MPEG-2 transport stream) and converts to a 320x176 (16:9 aspect ratio, 29.97fps) file for my 5g ipod.
But any MPEG-2 encoder should work - but you'll need to tell it to create a ".m2v" raw video stream, or if your encoder only generates .avi or .mpg files, then you'll need to find another tool to demux the .m2v stream before copying it to your player.
An important thing to remember is that MPEG-2 works with 16x16 blocks - so you should encode to a multiple of 16x16 - e.g. 224x176 for 220x176 LCDs, and 176x128 for the Nano's 176x132 LCD.

On my gen 5 the video is messed up, odd colours ect.
Llorean:
Rockbox always plans on supporting every feature of the hardware eventually. It's just a matter of how long.

Please edit when you quote...
What encoder did you use? It's been reported that mpegplayer has problems dealing with files encoded by ffmpeg (including mencoder). That's on my list of things to investigate.
