mplayer plays it fine, and says it's MPEG-4.

Ah, you're just the person I ought to ask about this; can you suggest an ffmpeg rune that would produce a .MPG file that can play in a standard player?

I produced the video with 'ffmpeg -i frame%03d.png foo.avi'; 'ffmpeg -i frame%03d.png foo.mpg' produces something that Totem can't play.

I wonder whether I'm missing some unspoken requirement for all my frames to be 352x288 or similar.

I'm afraid all my MPEG video encoding has been done with either mencoder or the special-purpose mpeg2enc.

I hadn't heard of Totem before, but it turns out to be installed on my Linux box. Unfortunately when I converted your video into a bunch of PNGs and ran your command above, it played the resulting foo.mpg fine, so it's hard for me to be sure that anything else that works for me will work for you too.

If it were me, I'd probably try adding something along the lines of -vcodec mpeg2video -f mpegts to the command line; but if that didn't work then I'd have no idea what to try next.

Hmmm...try asking ffmpeg what formats it supports; I think the command is "ffmpeg -formats". Unfortunately, you then have to pick a widely used one; MPEG-4 (if it's available in your version of ffmpeg) would probably work most places.

Also, hang on a minute. When I extracted the individual frame images from your video file, they were 352×288. Were they something else on input?
