[FFmpeg-devel] [PATCH 13/18] h264_redundant_pps: Fix looping over an access unit's units

[Andreas Rheinhardt]

When looping over an access unit's units in positive direction and
deleting some of them, one needs to make sure that a unit that is at
the position of a unit that just got deleted gets checked, too.
