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. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com> --- libavformat/mov.c | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-)
