It is placed inside a 'vids' struct, so it was being exposed on
a pad named video_%d. XSUB are subtitles and this patch adds
an special case for it to be exposed in a subpicture_%d pad
The audio packets in AVI are generally muxed ~0.5s before the
corresponding video packet. This changes causes downstream to only
receive packets with roughly corresponding timestamps.
... but disable this for now. Although it basically works fine,
user experience might be shaky (depending on taste), since there
is no keyframe info in push mode.
Implement scanning of the file when we can parse the index.
Some refactoring of common code.
Cleanups and comments.
Remove some reimplemented code.
Remove index massage code and put a FIXME where we should do something
equivalent later.
Remove some duplicate counters.
Be smarter when updateing the current the timestamp and offset in the stream
because we can reuse previously calculated values when simply go forward one
step.
Correctly set metadata on outgoing buffers.
Add a new function and datastructure to parse and hold the index entries on a
per stream base. Also avoid doing too much work trying to figure out the
timestamps and durations as we can trivially do that later.
Less information in the entries makes them 2 times smaller and not doing too
much work makes this code about 12 times faster than the regular case.
Hook in the new function alongside the existing function for comparison until
the rest of the code is updated to handle the new index datastructure.

* gst/avi/gstavidemux.h:
For timestamping audio packets we need to take into account the
amount of blocks in one entry using the blockalign. Fixes some sync
issues with zero-padded audio blocks in the beginning of avi files.

Parse subtitle text streams instead of erroring out (#442034). Still
needs a parser for the subtitles to actually show up.

sub-indexes.

scanning). More broken media support. EOS workarounds. General AVI
braindamage headache recovery. Aspirin included.
