3df615a503 mxfmux: Write This Generation UID into the Identification metadata
It's required according to the standard and we forgot to actually write it to
the file although we stored it in the data structures.

b6696122a0 mxftypes: Don't store pointers in stack allocated guints
This works usually in this place, unless the compiler optimizes things in
interesting ways in which case it causes stack corruption and crashes later.

The compiler in question here is clang with -O1, which seems to pack the stack
a bit more and causes writing to the guint as pointer to overwrite map.memory,
which then later crashes during unmapping of the memory.

7ae23d13c8 mxfdemux: Only pre-set position for exactly the same essence track
The edit rate is only supposed to be the same in a source package, but there
might be multiple source packages with the same essence container. As such
just comparing the body/index SID is not sufficient.

6e06f8c936 mxfdemux: Use keyframe information from index table segments if available
We don't implement keyframe detection for all codecs and this will allow us to
implement better seeking.

b504672fc4 mxfdemux: Collect all index table segments after finding the random index pack
That way we always have the index table information available, especially the
keyframe-ness of all buffers.

6d367d6b48 mxfdemux: Fix handling of IndexTableSegments
This was completely broken before and could only work on a very constrained
set of files. After these changes it should work except for situations where
PTS != DTS, which is not handled at all in mxfdemux currently.

a02708f924 mxfmux: Add FIXME about enforcing that all tracks in a source package have the same edit rate
The standard requires this and also the index table segments are not going to
work otherwise.

01f0d16db3 mxfmux: Index table segments must not use the primer pack
According to S377-1-2009c 9.2 the local tags must not be resolved from the
primer pack, which as a result means that there can't be any other tags than
statically assigned ones.

73beb1834e mxfmpeg: Use the correct sound essence compression UL for MP3
There's one for MPEG 1 Layer 1 and one for Layer 2 and 3. We previously
had the second for Layer 1 and 2 and nothing for Layer 3, which was wrong.

adb01a23da mxfmpeg: Set the essence container UL byte 13 to 0x10 for h264
0x04 signifies a MPEG elementary stream but according to RP2008, 0x10 should
be used for a h264 byte-stream. This also fixes compatibility of our files
with ffmpeg.
