looks like i was wrong about 64bit ffmpeg's abilty to do avs in and ffvhuff out. it does actually work in many cases but fails with others.
zathor, can you change the pre-rendering to use this easily? it would make it easier to test.
Code:
ffmpeg -i input.avs -vcodec ffvhuff -context 1 -vstrict -1 -an output.avi
and any thoughts on memory behavior?
i forgot to add:
the memory problems occur only when using ffms, not directshowsource. unfortunately i can't duplicate the issue on the commandline.
