By adding the video-source-filter during construction time, rather then
patching it in later (*), we can greatly reduce the amount of caps involved
in negotation, speeding up pipeline creation.
I wrote this while working on speeding up the startup of cheese. My cheese
has been modified to add a capsfilter, filtering for only the configured
resolution, with that cheese patch + this patch, the pipeline creation time
goes from aprox 1.1 seconds to aprox 350ms. This is with a Logitech 9000
pro camera, which supports lots of different resolutions at many different
framerates per resolution, causing a caps "explosion" if not filtered.
*) Note the code for this is left in, as it is still necessary if the
video-source-filter is changed between a stop + re-start.

check_and_replace_src() was setting self->app_vid_src to NULL, which
means that an app setting the video-source property, and then starting,
stopping and re-starting the pipeline (ie to make changes to the
video-source-filter property) would after the restart no longer have
a video-source.
This patch fixes this by making gst_camerabin_setup_default_element return a
ref to the passed in user_element, rather then returning the user_element as
is, so that that ref can be passed on to the bin, and the app_vid_src ref
stays valid.

Current fallback to lost_sync seems to impede a delay to restore
sync. Let the parser parse and skip the private stream.
Here it contains the digital camera brand (in 2010 bytes)
and is repeated twice.

descriptors are stored as a GValueArray of GString. The downside is
that there is no way to "pass" ownership of a GValue to a GValueArray
which previously resulted in expensive copy/free of the (already expensive)
GString.
Here we estimate first the size of the GValueArray, then create it,
then directly use the GValue of that array.
Speeds up total SI parsing by ~30%
If rfb_decoder_new() allocates the decoder sructure, rfb_decoder_free()
should free the structure. We should not free the decoder when an
error occurs during connection - it holds lots of configuration/state
and will be freed later in finalize.
prepare_func will allocate a new buffer to replace the original
one. Instead of using gst_buffer_replace (which causes an extra
refcount increment on the new buffer), we just unref the original
buffer.

Don't send any source caps yet if we're still in
drop-buffers-until-we-get-a-sequence-header mode.
Fixes transmuxing of many MPEG-TS/PS streams into
formats which require things like width, height or
codec_data on the input caps.
Also fixes issues when using playbin with decoder
sinks that want width/height etc.

Since there is a conflict between the DCII stream type and BluRay
stream types, moved the processing of BluRay-specific stream types
to the beginning of the function. Only if a BluRay stream type
IS NOT found do we proceed to check the rest of the stream type
identifiers
Previous code was also "sort-of" handling a similar conflict between
BluRay AC3 audio and standard AC3 audio. Moved the special case BluRay
AC3 handling in the main switch statement to the new BluRay-specific
switch.

The src element may not include information about whether
the data is parsed or not. Hence do not require parsed=false.

And if we detect a discontinuity there (like... when losing packets
or having MPEGTS over raw UDP with out-of-order packets) we just
drop the corresponding packet.
A future version could try to implement a re-ordering algorithm based
on that, similar to what rtpjitterbuffer does.
Backport fix for crashes and invalid writes in totem from libvisual
in -base, to minimise differences to version in -base and to make
sure the bug doesn't sneak back in later when the base class is
made public.
The shader code looks like it makes assumptions that are not
necessarily always true, even if they're true for now for the
existing elements, namly that pixel stride is 4, for example.

gst_query_set_nth_allocation_pool() requires there to be a pool in the
query already. This is not always the case when we get the query from
upstream. Use gst_query_add_allocation_pool() instead in such case.

When converting the incoming segment from byte to time format,
don't just convert the start/stop/time values, but also change
the segment format to TIME.

Rework things a bit so that we can run over the midi events and fire callbacks
for each of them. We can then use that for calculating the duration and also for
doing playback.
Only parse as many tracks as specified in the header.
Fix default tempo;
Send MIDI tick events every 10ms
