[FFmpeg-devel] [PATCH] Revert "avformat/mov: disallow a zero sample size in trun atoms"

[Chris Ribble]

This reverts commit 03d81a044ad587ea83567f75dc36bc3d64278199.

This change broke the ability to read mp4 files which contain a trun
atom with a sample of size zero (FFmpeg exits while parsing the moof).
