rtpjitterbuffer: Make it more explicit that update_rtx_timers() takes ownership of the passed in timer

It is not valid anymore afterwards and must not be used, otherwise an

rtpjitterbuffer: Change RTX timer availability checks to assertions

It's impossible to end up in the corresponding code without a timer for

rtpjitterbuffer: Only unschedule timers for late packets if they're not RTX packets and only once

Timers for RTX packets are dealt with later in update_rtx_timers(), and
timers for non-RTX packets would potentially also be unscheduled a
second time from there so avoid that.

Also don't shadow the timer variable from the outer scope but instead
make use of it directly.

Ideally the multicast address should be checked after allocating but
this doesn't happen currently, so it's better to error out cleanly then
to loop forever trying the same address.

bin: Don't propagate state change errors of elements in locked state

Theoretically having elements in locked state should not have any effect
at all when the surrounding bin is doing state changes. However
previously a state change error of a locked element would cause the
bin's state change to also fail, which is clearly not intended.

State change failures of locked elements are to be handled by whoever
set the element to locked state. By always returning them here it is
impossible for the owner of the element to handle state change failures
gracefully without potentially affecting the whole pipeline's state
changes.

Non-failure returns are still returned as-is as the distinction between
ASYNC/NO_PREROLL/SUCCESS has big consequences on the state changes of
the bin and overall pipeline. Theoretically SUCCESS should also be
returned in all cases but I can't estimate the effects this would have
on the overall pipeline.

cuda: Hide runtime compiler related header and symbols

That's already abstracted via gst_cuda_nvrtc_compile() method
and therefore, we do not need to expose such symbols yet.

vajpegdec: Fix 4:2:2 for i965.

Since i965 uses NV12 either for 4:2:0 and 4:2:2 chroma (using an
internal color conversion) the chroma validation has to be shortcut.

va: Validate JPEG subsampling configurations.

There are Mesa Gallium drivers that report subsampling but without
any pixel format. So, strip out these subsamplings.

vaapi: plugin: Handle when no encoders/decoders available.

Nouveau driver currently only exposes postproc entry. But
vaapidecodebin is registered independent if there are decoders or not,
exposing a segmentation fault.

This patch removes the encoder/decoder/codec arrays if no entries are
found, and if no decoders are found vaapidecodebin is not
registered. Also for vaapipostproc if no postproc entry is found.

Also, if general decoder, used by vaapidecodebin, doesn't have a sink
pad string, don't register the glib type.

gst-play: missing cleanup for g_autoptr

Without this change cleanup function for g_autoptr is not defined for
GstPlayMediaInfo, GstPlaySignalAdapter, GstPlayVideoRenderer,
GstPlayVideoOverlayVideoRenderer and GstPlayVisualization. Cleanup
function was defined in gstplay.h, but missing in other header files.

splitmuxsrc: Stop pad task before cleanup

When stopping the element, make sure the pad task
is stopped before destroying the part readers.

Closes a race where the pad task might access
a freed pointer.

Also add a guard against this sort of thing
by holding a ref to the reader in the pad loop.

v4l2bufferpool: Fix debug trace

The tracing of the buffer pointer was done on the secondary pointer, which
does not match with other traces of the same buffer. This made the trace
confusing and less useful.

adaptivedemux2: Fix for period switching in live streams

When playing live, it's possible that one stream reaches
the end of the available playback window and goes to sleep
waiting for a manifest update, and the manifest update
introduces a new period. In that case, the sleeping
stream needs to wake up and go 'properly' EOS before we
can advance the input to the new period.

Accordingly, make sure that a stream's last_ret value
is not marked as EOS if it's just sleeping waiting for a live
manifest update.

Also fix the output loop to go back and re-check if it's
time to switch to the next period after dequeuing and
discarding an EOS event.

mssdemux2: Use gsturi structure to form fragment urls

Utilize gsturi to form fragment url paths.
A token query may contain the string "manifest" and this would lead
to improper url creations.

meta: Set the parent refcount of the GstStructure correctly

The parent refcount is of the *transformed* buffer, not the input
buffer.

Also update the docs to clarify that @transbuf is the transformed
buffer, and not the buffer on which a transformation is being
performed.

Due to this bug, modifying the structure of a meta that has been
copied to another buffer fails with:

gst_structure_set: assertion 'IS_MUTABLE (structure) || field == NULL' failed

Add a test for the same.
