e5ff2c0c06 avformat/mxfdec: only return stream indexes which have a corresponding track 
Without this check some crafted files might crash because a packet might be
demuxed which have no corresponding mxf track.

For clip wrapped essences this should work. Also, since index_edit_rate can now

f50741147c avformat/mxfdec: always use a stream which matches the first index table when seeking 
Obviously this is still not perfect, but better then it was. Using the first
index table and mxf->current_edit_unit is still hardcoded in many places, so
this change has hopefully the less chance of breaking anything that works
now.

9492bb58ee avformat/mxfdec: use both body_sid and track_number to find the track of a packet 
In order to do that we have to parse the EssenceContainerData and assign the
proper body_sid and index_sid to the tracks from the corresponding source
packages.

This fixes packets returned in the wrong stream for some OP1-b files.

5a93a85fd0 avformat/mxfdec: fix last packet timestamps 
The current edit unit cannot be reliably determined for the last packet of a
video stream, because we can't query the start offset of the next edit unit
from the index. This caused missing timestamps for the last video packet.

Therefore from now on, we allow setting the PTS even if we are not sure of the
current edit unit if mxf_set_current_edit_unit returned a specific failure, and
the assumed current edit unit is the last.

Fixes last packet timestamp of:
