726ea62d25 mxfdemux: Handle non-frame wrapping
* If we have an index table for non-framed essence, we can handle it

* The demuxer has a state which indicates whether it will next fetch a KLV or
data contained *within* a KLV.

* The position on Essence Tracks always correspond to the next entry to fetch,
demuxer offset will be skipped accordingly whenever we switch between
partitions (in case of resyncs). A copy of the main clip/custom KLV for that
partition is kept to track the position within the essence of that partition.

* For clip/custom-wrapped raw audio, if the edit rate is too small (and would
cause plenty of tiny buffers to be outputted), specify a minimum number of edit
units per buffer.

38ec61c586 mxfdemux: Use KLV for position/content tracking
* For pull-based, this avoids pulling content if it's not needed (ex: skipping filler
packet, not downloading the content if we only need to know if/where an essence
packet is, etc...). Allows reducing i/o usage to the minimum.

* This also allows doing sub-klv position tracking, and opens the way for
non-frame-wrapping handling

ac483b2384 mxfdemux: Refactor index table and offset handling
* Streamline offset <=> entry handling. Historically the demuxer didn't support
information from index tables and stored the discovered information in an array
per track. When index table support was added, a parallel system was setup for
that relationship. This commit unifies this into one system with the
`find_edit_entry()` and `find_entry_for_offset()` functions.

* By extension, per-track offset entry tables are only created/used if no index
table is present for those tracks.

* Use index table information as-is. The index table system from MXF is quite
complex and there are various ways to use the information contained
within. Instead of converting that information we store the data from the tables
as-is and extract the needed information when needed.

* Handle index tables without entries (i.e. all content package units are of the
same size).

* Allow collecting index table segments as we go instead of only once if a
random-index-pack is present. This also improves support of some files in
push-mode.

* When searching for keyframe entries, use the keyframe_offset if
present (speeds up searching).

* For interleaved content (i.e. several tracks in the sample essence container),
we use a system to be able to identify the position of each track in the delta
entries of index tables.

* Handle temporal offset only on tracks which *do* need it (as specified in the
delta entries of the index tables). If present, those offsets are stored in a
pre-processed table which allows computing PTS from DTS with a simple offset.

* Add a quirk for files which are known to be have wrongly stored temporal
offsets.

* Overall opens the way to handle more types of MXF files, especially those with
non-frame-wrapping.

dfee771afd mxfdemux: Handle temporal reordering shift
This is similar to how the same issue was handled in qtdemux.

In order for the "DTS <= PTS" constraint to be respected, we calculate the
maximum temporal reordering that can happen (via index tables).

If there is a non-0 temporal reordering, we:
* Shift all outgoing PTS by that amount
* Shift segment for that stream by that amount
* Don't modify DTS (i.e. they might end up having negative running-time, before
the start of the segment)

Also ensure all entries have a valid PTS set, previously this wouldn't be set
for entries with a temporal offset of 0.

Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/issues/584

(and maybe a lot of other issues)

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).

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.

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.

Remove the concept of "final" metadata, broken files have updated
metadata in following partitions even if the current partition
is closed and complete.
If there's a second primer pack inside a partition ignore the second
one instead of throwing an error.
Store the type of a track (audio, video, timestamp, ...) inside the
track struct.
Post no-more-pads only once for a stream and not a second time
when switching the currently playing package.
When updating all streams make sure that we could select and find
a package instead of dereferencing NULL.
Allow descriptive metadata inside metadata parts of a file when
pulling the footer metadata too.
Only switch the currently playing package if a new one was chosen
and the metadata is in a resolved state. If the latter isn't true
postpone the switch until the metadata is resolved.
Pull the footer metadata directly after parsing the header partition
pack if it's not closed or not complete instead of waiting until
the next KLV packet.
