was this tested with all mov samples or just those high bitrate ones ? 

i am wondering if it helps/hurts demuxing the ancient mov samples we
also support. see the nightmares here https://samples.ffmpeg.org/mov/

if hurts, i wonder if buffer pools could be used only for specific high
bitrate codecs in mov demuxer? 

not important just curious. nice job on the speedup!
