Thiago, I tried to apply the patch to current git and had 2 hunks rejected line
2797 and line 2806.  Those 2 were just a GST_LOG_OBJECT that was moved, so I
tried to test anyway.  I tested 2 mp4 files (m4v/aac), both alternate 10 second
empty and non-empty segments, but one starts with an empty segment and the
other does not (See links to files below).

Your previous patch in #586848 resulted in successful playback of the video
that starts with a non-empty edit.  The one that starts with an empty edit does
not play at all (seek and position problems still apply).

Using this patch, neither file plays properly.  The mp4 that starts with a
non-empty edit only has the initial audio segment played (and no other). The
mp4 that starts with an empty edit doesn't play at all.

Note: Using quicktime, only the mp4 that starts with a non-empty edit plays
properly. The other one has a sync diff of about 2 seconds. Looking at the
dumpster output it seems its mediatime duration is shorter than expected, so
only use as test for starting with empty edit.. don't expect good sync.

FYI: The mp4's were created using the initial patch in #601576, with an updated
qtmuxedits test app (will likely submit updated patch at some point).
