Comment:

 Sounds like this is an upstream rpi firmware issue. However ffmpeg doesn't
 respect the zerocopy option when compiled for RPI which makes this hard to
 work-around. I'll work on a patch to default zerocopy to enabled on RPI
 builds but still let the user disable it in case they run into this bug.
