c2ef63a3bc mxfdemux: Keep track of component start positions and material track positions
This allows us to know exactly where in the material track we are, and
how to convert from a PTS for a source track to the actual PTS of the
material track (i.e. by adding the component start position).

72b7794798 mxfdemux: Allow filler and other KLV packets between index table segments
While only filler packets should be allowed, for good measure also skip
any other KLV packets in the range where there could be index table
segments.

This fixes parsing of partitions with multiple index table segments,
which are separated by a filler packet, or other packets.

830e89b7e9 mxfdemux: Take temporal reordering from the index table into account
This is needed to know the PTS, without that we only know the DTS and
using that also for the PTS is wrong unless we have an intra-only codec.

If we can't get the temporal reordering from the index table, don't set
any PTS for non-intra-only codecs and let decoders figure out something.

fd3854c3e3 mxfdemux: Do not try to serialize unresolved metadatas
When retrieving the `mxfdemux.structure` property, it leads to an
assertion as metadatas need to be resolved for the call to
mxf_metadata_base_to_structure to be valid.

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.

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.

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.

41982e6ccf mxfdemux: If seeking to the remaining parts of the file fails on EOS, consider the stream done

the same stream.

4d790dae67 mxfdemux: fix memory leak
Reset the internal segment before freeing it.

mxf_index_table_segment_parse() allocates data inside the segment
(like segment->delta_entries) which have to be freed using
mxf_index_table_segment_reset().

b7e0c7a163 mxfdemux: remove ignored value
Value stored in ret will be ovewritten in the next iteration of the loop. Which
means it is never used.

Plus a style issue to make gst-indent happy and allow the commit.

52981d5a4a mxfdemux: guard against NULL non source components
This component is dereferenced, and later code checking for
NULL in particular cases implies it can be NULL. This likely
does not fix the coverity warning as it was seeing another
path setting component to NULL explicitely, but this was
spotted by looking at:

Coverity 1139736

Which is actually OK from what I can see since the actual
dereference of the explicit NULL pointer will not happen
if the condition that led to the NULL pointer assignment
is met, since the assignment and defeference have mutually
exclusive tests.
