With the VPX decoders it's not simple to use downstream buffer pool,
because we don't know the image size and alignment when buffers get
allocated. We can though use GstAllocator (for downstream, or the system
allocator) to avoid a copy before pushing if downstream supports
GstVideoMeta. This would still cause a copy for sink that requires
specialized memory and does not have a GstAllocator for that, though
it will greatly improve performance for sink like glimagesink and
cluttersink. To avoid allocating for every buffer, we also use a
internal buffer pool.

This adds an automatic mode to the threads property of vpxdec in order to
use as many threads as there is CPU on the platform. This brings back
GStreamer VPX decoding performance closer to what is achieved by other
players, including Chromium.

When jpeg_finish_decompress is called, output state reference is being created.
But if there is any failures in finishing decompress, it jumps to setjmp,
and at that point state was not referenced. Resulting in leak of output state.
Hence adding another setjmp after output state is referenced.
Similarly adding another setjmp to unmap the frame in case error happens before
finish_decompress

The problem is that the filesrc and souphttpsrc are behaving
differently regarding the calculation of the segment boundaries. The
filesrc is using a non-inclusive boundaries, while the souphttpsrc
uses inclusive. Currently the hlsdemux calculates the boundaries as
inclusive, so for this reason there is no problem with the souphttpsrc,
but there is an issue in the filesrc.
The GstSegment is non-inclusive, so the proposed solution is to use
non-inclusive boundaries in the hlsdemux in order to be consistent.
Make the change in the hlsdemux, will break the souphttpsrc, which
will expect inclusive boundaries, but the hlsdemux will offer
non-inclusive. This change makes sure that the non-inclusive
boundaries are converted to inclusive.

We don't necessarily have full control over the input tags, so
it's possible that the ISRC tag contains a longer string than
expected, in which case we'd write over the end of the static-size
13 byte buffer that is FLAC__StreamMetadata_CueSheet_Track::isrc.
Make sure to only copy the ISRC if it's not too long, and make
sure the buffer we write to is always NUL-terminated by using
g_strlcpy().

Should just compare with what can be immediatelly accepted by
the element. flacenc can't renegotiate so if it has a caps already
it should only accept if it is that caps otherwise just use the
template caps
Removes the need for custom caps query handling and makes it more
correct from the beginning on the template. It is a bit uglier
to read because there is 1 entry per channel but makes code easier
to maintain.
Some files may provide different caps insight of one stream. Since
vp9enc support caps reinit, we should support cache reinit too.
If more then file cache file will be created, the naming will be:
cache cache.1 cache.2 ...

1) If the system http_proxy environment variable is not set
or set to an empty string, we must not set proxy to avoid
http connection error.
2) In case of proxy property setting, if user want to clear
the proxy setting, they should be able to set it to NULL or
an empty string again, so this is fixed too.
3) Check if the proxy string was parsed correctly.

The framerate very often is just an indication of the ideal framerate, not the
actual framerate of the stream. By just using the framerate, we confuse the

In pulsesink_query function, we use a switch for the query

Set positioning-mode=pixels-absolute to allow positioning with
absolute coordinates, meaning negative x/y offsets will be
interpreted as being to the left/above the video frame instead
of being interpreted as relative to the right/bottom edge of
the video frame (which is a silly default, but that's how it is).
This means we can nicely slide images into and out of the frame,

http://www.wavpack.com/file_format.txt:
"Both the APEv2 tags and/or ID3v1 tags must come at the end of the
WavPack file, with the ID3v1 coming last if both are present."
WavPack files that contain APEv2 tags at the beginning of the files
are unplayable on players that use FFmpeg (like VLC) and most other
software (except Banshee). Players that use libwavpack directly can
play the files because it skips the tags, but does not recognize the
tag data at that location.

This avoids _set_format setting the unpositioned flag when passed

Right now in parse logic the signature is checked every time the parse function
is called, and the whole data is the scanned each and every time, even though the
data is scanned in the previous instance. Changing the logic such that, we skip
the bytes which are already scanned in the previous instances of parse. This
helps in avoiding multiple scan of already scanned data/signature.

We need a mechanism in PulseAudio to allow running code outside the
mainloop lock. Then we'd be able to post to the bus (taking the
GST_OBJECT_LOCK), without worrying about locking order with the mainloop
lock, which is the current cause of deadlocks while trying to post the
stream status messages.

Stream headers are updated whenever ::set_caps is called, so we can't assume
they'll be valid before the message body is written out. We *can* assume that
for queued buffers, but SOUP_MEMORY_STATIC is still wrong for those.
Also, add some debug logging for stream header interactions.

::render sets a new callback for writing out new buffers only if there aren't
already buffers queued for writing with a previously-scheduled callback.
However, if the previously-scheduled callback is interrupted by a state change
(either manually or due to an error) and there are still buffers in the queue,
restarting the pipeline will result in buffers being queued forever, and no
callbacks will ever be scheduled, and no buffers will be written out.

This gives a quick introduction to how the pulsesink/pulsesrc code
interacts with the pa_threaded_mainloop that we start up to communicate
with the server.
The stream status messages are emitted in the PA mainloop thread, which
means the mainloop lock is taken, followed by the Gst object lock (by
gst_element_post_message()). In all other locations, the order of
locking is reversed (this is unavoidable in a bunch of cases where the
object lock is taken by GstBaseSink or GstAudioBaseSink, and then we get
control to take the mainloop lock).
The only way to guarantee that the defer callback for stream status
messages doesn't deadlock is to either stop posting those messages, or
make sure that the message emission is completed before we proceed to
any point that might take the object lock before the mainloop lock
(which is what we do after this patch).

When we cancel connection attempts and similar things, there are still
some operations pending on our main context from the GCancellables. We
should let them all run before unreffing our context, otherwise we leak
file descriptors.
Unfortunately this requires libsoup 2.47.0 or newer as earlier versions
steal our main context from us and we can't use it for cleanup later
without assertions and funny crashes.
