You could just do that. There is no need to write them anywhere though; you can pipe png sequences into ffmpeg directly (I create animations this way). I'm not familiar with vcdiff, but as long as you have a tool that produce a png on a standard output, you could loop over your diffs, piping the output info ffmpeg. Maybe you'll need a temporary variable storing the resulting png for the next step, but that will be held in RAM so no worries. Be careful if you do that though; binary data and shell script variables are not too friendly. I'd do that in python or another language. Once you have your script that output the sequence of png on it's standard output, you can pipe them to ffmpeg using '-' as the input name. Something like this: $ your_script | ffmpeg -f png_pipe -i - out.mp4 Don't forget to specify framerate etc. (of course, if ffmpeg does support such format by itself, ignore this message; I'm not familiar with *all* the stuff ffmpeg supports either). _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
