This muxer currently only supports OP1a and is
probably not yet 100% complying to the standards.

and played.

8172830d47 mxfdemux: Only store the main descriptor in source packages
For the tracks we still resolve the descriptors but the
source package only contains the descriptor it really references
instead of all subdescriptors of multiple descriptors.

This makes it easier later to serialize the structural metadata
again.

1229f0a149 mxfdemux: When trying to find an essence track position try to find position+1 too
By searching for the following position we will add the complete
generic container (i.e. all tracks) at the same position to the
index which should make finding positions for more than one track
a bit faster.

dc408bb28b mxfdemux: Fix seeking to the end of file
When seeking to a position where no new offset can be
found or after the end of a track don't set the EOS flag
to TRUE as we don't (and can't) push EOS downstream then.
Instead set the current essence track position to then
end of the essence track and let the loop or chain function
set everything to EOS and push EOS downstream.

Also restart the pad's task if resolving metadata failed
(playback will continue as before) and return FALSE from
the seek if no new offset could be found.

2b566be795 mxfdemux: Correctly implement timestamping in all cases
When the material package track and source package track
edit rate are different the source package track edit
rate applies to the stored essence and the material track
edit rate only applies to the values in the track's sequence
and components.

8dc9f2ea4d mxfdemux: Add support for non-standard Avid MXF files containing DNxHD essence
Avid uses a custom essence container UL and custom essence element keys
that are fortunately compatible with the generic container essence
elements. Partially fixes bug #561922.

3c3dff6869 mxfdemux: Make essence track creation a bit more robust against broken files
Some files contain multiple tracks with the same track number but different
track id inside the same source package. This is invalid and we simply ignore
the second and following of such traacks now instead of overwriting the
information of the first one.

6e392318c0 mxfdemux: Add support for non-standard Avid MXF files containing DV essence
Avid usually uses a custom essence container label for the essence
descriptors and stores the actual codec that is used inside the
picture essence coding field (and for sound probably in the sound
essence coding field but I have no sample files with sound).
Partially fixes bug #561922.

6208795598 mxfdemux: Add keyframe detection for MPEG2 video streams
This is useful for seeking as we usually want to seek to the previous
keyframe. The keyframe detection is done by parsing the MPEG2
elementary stream and if a GOP or I-frame packet is found we
assume a keyframe in this edit unit.

afbec8ab9b Allow index table segments without primer pack
When parsing an index table segment without a valid
primer pack in this partition only parse the static

264e30abb9 Improve detection of the end of the header metadata
Header metadata is finished after partition.header_byte_count
bytes after the first byte of the primer pack are handled.
After this there can only be index table segments, filler packets,
essence or the start of the next partition.

This fixes playback of some files that have non-standard metadata
packets in the header metadata.

716ce72e46 Store MXF metadata in a hash table, keyed by UID
Store the MXF metadata in a hash table, keyed by the
instance UID. This simplifies resolval of the metadata
and makes looping over all metadata sets unnecessary
in most cases.

Additionally parse metadata always. If we already have
a metadata set with the same UID replace it only if
the new metadata set is from a later offset. This
fixes metadata parsing of files where following partitions
don't have a complete copy of the previous metadata.
