Some container formats (like AVI) set DTS on the buffers instead of
PTS.
We detect this by:
* detecting if input timestamps are non-increasing
* detecting if the order the frames come out is the same as the order
they were inputted (meaning the implementation is reordering frames).
If the decoder reorders frames, but input buffer timestamps were not
reordered, that means the buffers has DTS and not PTS as their timestamp.
If this is the case, we use set the PTS of the outgoing frames in the
same order as they were given to the decoder.
This fixes the issue for any decoder using this base class (yay).
FIXME : Don't forget to backport changes that happened to theoraenc
since April 2011
theoraenc: Don't create keyframe on time gap
There is no rational to do so, and also gst_video_encoder_set_discont() is
gone from base class.
For example the Sintel subtitles have this and without this change
they're detected as text/plain and not usable as subtitles. The
parser itself already handles this just fine.
For streaming sources a queue is added before the demuxer, which can not be
properly filled by live sources. As http source can be live sources, this
caused issues for example with http live sources.

Avoid pushing out buffers with the same timestamp only if the out buffers are
decoded from the same input buffer. Instead keep the timestamps when upstream
pushes consecutive buffers with the same ts.
Adds a property for playsink to define how it should handle
events sent in send_event function. The default is the same as
GstBin's, sending events to all internal sinks. There is also
mode-first, that will send to sinks until the one handles the
event successfully.

gst_buffer_set_qdata() will leak the structure passed to it
when called incorrectly (e.g. on a non-metadata-writable buffer).
This is expected, but we must avoid doing that in valgrind.
Try to avoid floating point maths for each pixel to be blended in
inner loop, and try to avoid the multiplication entirely for the
most common case of the global alpha being 1. Could probably be
refactored a bit more.
extract_alpha and apply_global alpha always return TRUE really,
so just do away with the return value. Convert a g_return_if_fail()
into a g_assert(), since this is only to check internal consistency
and not a guard for public API. Add some locking.

When the video sink is a fakesink, which does not implement the
navigation interface, playsink will drop the navigation command.
In this case, send to the video sink as a fallback. It breaks
the interface abstraction, but is better than just dropping the
navigation event.
If we are asked to (un)premultiply,we need to create the new rectangle
with the right flags, so we can find it properly on subsequent cache
lookups (also because it's wrong otherwise).

We need to copy the pixels before messing with them, not least
because the buffer creation code below assumes it's ok to take
ownership.
Fixes crash caused by double-free.

Tremor changed to use standard libogg rather than its own incompatible
copy back in Aug 2010 (r17375), causing gst-plugin-base build to fail.
Tremolo so far unfortunately hasn't been updated. Restructure
vorbisdeclib.h so the int/float logic is seperate from the ogg handling,
and only use the legacy _ogg_packet_wrapper code for Tremolo.

Should fix issues with missing symbols for people who install GStreamer
from source and at some point jumped back and forth between git master
and the 0.10.36 release (or 0.10. branch).
