FFmpeg has an arbitrary allocation limit (2G iirc), av_fast_realloc()
increases the allocation even if the requested is equal the already
allocated size. I believe this can lead to unnecessary OOM (no
testcase) if the requested (and already allocated) size is close to
Additionally, this avoids an over-allocation for the mov stts patch I just sent.
Attached patch changes the behaviour introduced 15 years ago.
Please comment, Carl Eugen
