So, I was working on restoring direct copy support for cinelerra-cv and realized I can xcheck Cin-GG too.
I think attached two patches make it possible to skip de/encoding for unchaged portions of timeline when working with image lists of exr and ppm types (in addition to png/tiff/tga/jpeg support already there) Please test?
