[FFmpeg-devel] [PATCH] avformat/mov: Remove pointless EOF checks

[Andreas Rheinhardt]

9888ffb1ce5e0a17f711b01933d504c72ea29d3b added checks for EOF
in loops in the mov demuxer as a precaution against timeouts;
yet there is no I/O in the loop when parsing the STSZ atom
as the values are read from an already read buffer. So remove said
checks.
