Thanks. It doesn't appear to be compatible with my files. They are not .mov
files, they are .mp4. If I rename them to .mov, QuickTime player can still
play them. But when I send it the file with either name, qttoy4m complains
about the corrupted frames, even if I just use "qttoy4m infile.mp4 >
outfile.y4m". The .y4m file is created when I issue the command and the
process continues to generate the complaints, but the outfile length remains
at 0. I've let it run up to 20 minutes or so before killing it. The test mp4
contains no audio and is only 49 seconds in duration. I'm wondering if
something special has to be configured for the build for it to be able to
process these HD mp4 files.
