Function body must only be removed if compiling with
GST_REMOVE_DEPRECATED. Function declaration must not
be skipped if GST_DISABLE_DEPRECATED is defined, since
it contains our export decorator and we wouldn't export
the symbol as public API any more then since we compile
with GST_DISABLE_DEPRECATED.
Instead of trying to guess what profile to build, just get the possible
elements to use with the specified caps and determine the
EncodingProfile from it.

Otherwise it won't be possible to specify some profiles such as
video/x-h264,profile=(string)high-4:4:4
With this patch, we can do
video/x-h264,profile=(string)high-4\:4\:4
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.
It is the only thing gst_pb_utils_init() does and it could be
automatically called from the places in pbutils it is needed.
After 1.14 we should deprecate gst_pb_utils_init().

There is a race going on somewhere when we attempt to remove elements
*while* the parent container is switching to PLAYING.
In order to avoid this issue with discoverer, make sure we never
remove elements while switching to PLAYING.
This would result in a lot of warnings regarding elements not being
in NULL state when removed, or even leaked elements.
Instead make sure we take the lock and check whether we are processing
or not before allocating or adding anything to the pipeline
And monitor no_more_pads.
With live sources such as rtsp, uridecodebin only creates its
child decodebins between PAUSED and PLAYING.
This means that the ASYNC_DONE it posts when getting NO_PREROLL
in its change_state method gets immediately propagated by the
GstBin parent class, as opposed to a situation where a
decodebin has been added to it already, and has posted ASYNC_START.
The proposed solution, instead of simply waiting for ASYNC_DONE,
and finishing prematurely in that case, waits for three conditions
to be true:
* the uridecodebin needs to have emitted no_more_pads
* its current state must be PAUSED if not live, PLAYING otherwise
* There must be no "pending subtitle pads", ie pads where we haven't
received tags yet.
All these conditions are checked in the message handler, as we
post custom messages on it when we get subtitle tags or no_more_pads.

Child streams could have more accurate width/height or various other
information added. If they have the same name, they are likely to be the
same streams.
