17f11c2cda playbin3: Add lock to protect buffering messages
Fix a small race where a group can receive stream-start
and post a pending buffering message just as another
thread posts a different buffering message, causing them
to be received by the application out of order. In the
worst case, this leads the application receiving a
stale 99% buffering message and going back to buffering
right after the 100% buffering message.

8983696e39 decodebin2: raise multiqueue max-size-bytes
The earlier size of 2 MB was set back in 2009, it doesn't
seem unreasonable to raise it to 8 MB these days. The use
case at hand is matroskademux containing both a video stream
with a very low amount of compression but no decoding latency,
and a H265 stream.

6d7dc93a45 uridecodebin3: Nullify current item after all play items are freed.
There's a potential race condition with this sort of pipelines on
certain systems (depends on the processing load):

GST_DEBUG_DUMP_DOT_DIR=/tmp \
gst-launch-1.0 uridecodebin3 uri=file://stream.mp4 ! glupload ! \
glimagesink --gst-debug=*:4

Right after the pipeline passes from PAUSED to READY, bin_to_dot_file
dumps uridecodebin3 properties, but current uri and suburi might be
already freed, causing a potential use-after-freed.

This patch makes NULL the current item right after all the play items
are freed.

78df7ae771 decodebin3: Only unblock for GAP events and buffers.
An alternate fix for
https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/merge_requests/1239
and https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1236
that makes it clear the intent is to only unblock on a GAP event, and
not any others.

1d833eba60 parsebin: fix critical when sorting pads
If the pad does not have a current caps, get_pad() returns the query
caps which can be ANY. In such case the caps does not have any structure
resulting in a critical warning when calling gst_caps_get_structure().

42597181e2 playbin2/3: autoplug/caps: don't expand caps to ANY
Retrieving the pad template caps from a ghost pad returns ANY which when
merged with any other caps will return ANY.  ANY is not very specific
and may cause suboptimal code paths in e.g. decoders that assume the
lowest common denominator when presented with ANY caps.

Fixes negotiating dma-buf with vaapidecodebin between glupload in the
video sink element.

71c3141672 uridecodebin3/urisourcebin: Reusability fixes
Improvements to uridecodebin3 and urisourcebin so that they are
reusable across a PAUSED->READY->PAUSED transition.

Disconnect and release decodebin3 request pads when urisourcebin
removes src pads.

In urisourcebin, make sure to remove src pads that are exposed
directly (raw pads and static typefind srcpads) when
cleaning up.

Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/768

e06ac494b8 playbin3: Always register 'playbin3' element.
If the USE_PLAYBIN3=1 env var is set, we want to replace
playbin with playbin3, but separate to that, we always
want to register the 'playbin3' element so that applications
which explicitly use playbin3 work regardless of the env var.

This fixes `USE_PLAYBIN3=1 gst-validate-launcher`, for example.

33ad1cdc5e playbin3: Avoid group deactivation deadlock.
Change locking around group deactivation to avoid deadlocks
when shutting down exactly as a buffering message arrives.

The PLAYBIN3_LOCK now protects the active field of the
source group. Everything else is still protected by the
source-group-lock.

Also properly protect group switching operations with
the PLAYBIN3_LOCK everywhere.
