b660f258a6 theoradec: make sure the selected pool accepts the new config
If gst_buffer_pool_set_config() fails then the pool will use its old
config. This may include different width or height when
pic_width/pic_height != frame_width/frame_height.
As a result, the assertions in theora_handle_image() will fail.

So check the result of gst_buffer_pool_set_config() and only use the pool
if it succeeds. Otherwise let the parrent decide_allocation() create a new
pool.

84dea99132 appsrc: properly handle events received before sending the segment
The first serialized events that can be send on a src pad are a CAPS and then a
SEGMENT event.

When handling events from user in appsrc, we used to send a segment
automatically if the SEGMENT has not been sent yet.
This breaks if the CAPS event was not send either as we were now sending
a SEGMENT before the CAPS.

Fix this by delaying such events until the CAPS has been configured.

96a46e31c7 appsink: add propose_allocation support
Adding propose_allocation is to meet the requirement of Application to
request buffers. Application sometimes need to create buffer pool
and request buffers to maintain buffer management itself, and Gstreamer plugin
import Application's buffers to use. So, add propose_allocation in
appsink like waylandsink and kmssink etc.

84a3b0ef87 samiparse: fix handling of self-closing tags
We would check the wrong string (rest of line rather than element)
for the / suffix of self-closing tags, which is not only wrong but
also has atrocious performance with certain strings like the garbled
nonsense clusterfuzz feeds us, which might cause discoverer to time
out when processing garbled SAMI files.

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=47461

bf9092592e appsink: Fix race condition on caps handling
Background:

Whenever a caps event is received by appsink, the caps are stored in the
same internal queue as buffers. Only when enough buffers have been
popped from the queue to reach the caps, `priv->sample` gets its caps
updated to match, so that they are correct for the following buffers.

Note that as far as upstream elements are concerned, the caps of appsink
are updated immediately when the CAPS event is sent. Samples pulled from
appsink retain the old caps until a later buffer -- one that was sent by
upstream elements after the new caps -- is pulled.

The race condition:

When a flush is received, appsink clears the entire internal queue. The
caps of `priv->sample` are not updated as part of this process, and
instead remain as those of the sample that was last pulled by the user.

This leaves open a race condition where:
1. Upstream sends a new caps event, and possibly some buffers for the
   new caps.
2. Upstream sends a flush (possibly from a different thread).
3. Upstream sends a new buffer for the new caps. Since as far as
   upstream is concerned, appsink caps are the new caps already, no new
   CAPS event is sent.
4. The appsink user pulls a sample, having not pulled before enough
   samples to reach the buffers sent in step 1.

Bug: the pulled sample has the old caps instead of the new caps.

Fixing the race condition:

To avoid this problem, when a buffer is received after a flush,
`priv->sample`'s caps should be updated with the current caps before the
buffer is added to the internal queue.

Interestingly, before this patch, appsink already had code for this, in
gst_app_sink_render_common():

    /* queue holding caps event might have been FLUSHed,
     * but caps state still present in pad caps */
    if (G_UNLIKELY (!priv->last_caps &&
            gst_pad_has_current_caps (GST_BASE_SINK_PAD (psink)))) {
      priv->last_caps = gst_pad_get_current_caps (GST_BASE_SINK_PAD (psink));
      gst_sample_set_caps (priv->sample, priv->last_caps);
      GST_DEBUG_OBJECT (appsink, "activating pad caps %" GST_PTR_FORMAT,
          priv->last_caps);
    }

This code assumes `priv->last_caps` is reset when a flush is received,
which makes sense, but unfortunately, there was no code in the flush
code path resetting it.

This patch adds such code, therefore fixing the race condition. A unit
test demonstrating the bug and testing its behavior with the fix has
also been added.

19b638debe appsrc: Store strong references to the expected buffers in the tests
Otherwise the buffers might already be freed as they were only owned by
the GstSample / appsrc and potentially don't survive until the pad
probe, as observed in some CI runs of the tests.

c9b127dae3 video: Add NV12_16L32S aka Mediatek MM21 support
Unlike other simple tiled formats, the Mediatek HW use different tile size
per-plane. The tile size is scaled according to the subsampling. Effectively,
using the name 16L32S to represent linearly layout tiles of size 16x32 bytes
in the Y plane, and 16x16 in the UV plane. In order to make this specificity
discoverable, a new SUBTILES flags have been added.
