[FFmpeg-devel] [PATCH 2/2] avformat/mov: increase current_sample after reading, to avoid discontinuous sample

[Zhang Rui]

Discontinuous sample could cause corrupted image if next video frame
is non-key frame.

Mostly, avio_seek() fails on I/O error for http/ftp/... stream.
In my opinion, retry is better than skip.

This line was first introduced in 2006 by commit b72708f8f.
I'm not sure if it worth an option to enable the new behaviour,
and keep the default behaviour as before.
