[PD] pdp_qt legal dimensions

Hello all,

I need to have control of a video file. To step image by image through a video on linux. As far as I can tell pdp_qt is the only object which can do this.

I am using the debain unstable packages of pd, pdp and pidip.

I have had a very hard time making a quicktime file which pdp_qt will accept. As quicktime is not a very well supported on Linux, it is hard to find a way of making these. ffmpeg seems to be broken, can't even play it's own quicktimes. Finally I borrowed a Mac, and produced a mjpeg quicktime with quicktime, but this one does not play either:

WARNING: request to create image packet with illegal dimensions 700 x 560

And pd is hung have to ctrl^c on the console to kill it.

I wonder what are the legal dimensions?

Thanks,
