c024c5e3bf gstgldmabufbufferpool: use gsteglimagecache
Store the imported GstEGLImage in a GstEGLImageCache. Since this passes
ownership to the cache, stop unreffing the images from the GstMemory.
Free the cache when the buffer pool is stopped.

f18d6fcb40 glupload/egl: Extract EGL image cache and make it public
Extract the EGLImage cache from gstglupload.c, place it in a separate
source file gsteglimagecache.c, and make the API public, so it can be
reused by the gldownload element.

1ef9f6ab26 glcontext/egl: Fix use of uninitialized memory
At least some Mesa drivers (see llvmpipe_query_dmabuf_modifiers()) don't
initialize the provided external_only array, so some format/modifier
combinations could get incorrectly marked as only external.

Make sure we zerofill the array before passing it to
eglQueryDmaBufModifiersEXT().

188b626ffc gldownload: import DMABufs from downstream pool
* if downstream provides us with a pool that can allocate DMA buffers,
  gldownload wraps it into a GL buffer pool that uses
  glEGLImageTargetTexture2DOES() to import dmabuf into textures
* upstream GL elements can allocate from that pool
* gldownload unwraps DMA buffers from incoming GL buffers and passes
  them downstream

835e232e8c rtspsrc: Use a flow combiner at the source pads instead of custom logic
Most importantly, this ensures that UDP streams still continue to run even if
they are not linked for a while. With decodebin3 the pads will all be unlinked
unless selected, and selecting a stream at a later time would otherwise switch
to a stream with a stopped udpsrc.

Apart from that this also ensures that actual errors from handling RTP packets
between udpsrc and the source pads are not silently ignored but considered
errors like they would be for TCP/interleaved.

225d6b7e11 v4l2videodec: fix freeze race condition
This fixes a possible deadlock between gst_v4l2_video_dec_change_state
and gst_v4l2_video_dec_loop on the buffer pool.

When stopping capture, the flushing state of the v4l2 capture buffer
pool gets reverted in the processing loop after it was set via
gst_v4l2_object_unlock (self->v4l2capture) (in
gst_v4l2_video_dec_change_state). As a result, gst_v4l2_video_dec_loop
does not return and consequently, gst_pad_stop_task gets stuck waiting
for the GST_PAD_STREAM_LOCK. To circumvent this, skip acquiring the
buffer pool if stopping capture.

b433d72a4d cccombiner: expose input-meta-processing property
It can be used to discard closed captions from the input pad if the
matching video buffer already held closed captions.

It is useful in a scenario where captions are generated for an AV
stream, but the incoming stream already has embedded captions for
some intervals, and those original captions should be preferred.

It can also be used to make sure input CC meta is always dropped,
the default behavior remains to append aggregated CC to whatever
CC meta was already present on the input video buffer

e2d388000c qt(6)/material: ensure that we always update the context in setBuffer()
Scenario is that there are two (or more) GstGLContext's wrapping Qt's GL
context from either multiple qml(6)glsink or qml(6)glsrc elements.  Call flow is this:

1. material 1 setBuffer()
2. material 1 bind()
3. material 2 setBuffer()
4. material 2 bind()

If the call to setBuffer() reuses the same buffer as previous call, then the
qt context is not updated in the material.  If however the previously used qt
context by the material had been deactivated or freed, then bind() would fail
and could result in a critical like so:

Some streams in the wild have empty segments at the beginning and
hlsdemux2 use to stall forever while we can handle it by processing
the following ones. The gap handling mechanism in adaptivedemux2
works properly and pushes the required gaps.

When the driver does not implement ENUM_FRMESIZE for some specific

assuming the driver can scale to any sizes.

Ensure that the original size is in the caps to prevent this assumption.

2766e4816a v4l2object: Fixed framerate negotiation
We had a problem with negotiation of the framerate.

Gstreamer was querying the FRAMEINTERVALS based on the max frame size
instead of the desired frame size.

This was resulting in non-negotiated errors when trying to run with a
smaller frame size and fps higher than the max for the max image size.

Fx the max framerate for 1024x1024 RGB on CMOSIS4000 is 28.292
While for 1024x100 RGB it is 280.867

But Gstreamer would allow any framerates bigger than 28.292 no matter
the frame size used...

I have fixed it by 1st changing the CAPS query to use the minimum frame
size instead of maximum.
This however has the downside of allowing gstreamer to negotiate
framerates that are too high if the image size is bigger than the
minimum.
This is not a huge problem since our driver just CLAMPS the fps value to
the max then.

However gstreamer was not being properly notified of this change, and
would therefore report a wrong fps in the CAPS structure.
Note that the fps would be correct inside the buffer info.
Since gstreamer was reading the fps back after setting it.
It was just not being "propagated" to the CAPS structure.
I have also added a WARNING to this point so we can see if the fps that
gstreamer tries to apply was accepted or not.

And the next part of the fix was to add a framerate check after the
frame size has been established.
I did this inside the fixate_caps function of the v4l2src, which was
calling the TRY_FMT in order to check if the format was correct.
So I just added a check for the ENUM_FRAMEINTERVALS in there.

And now we get the non-negotiated again if the fps is too high for the
selected frame size.
Also added a couple of warnings so it is easy to see that this was the
cause.

Use a different algorithm which offers better result and keep the
performance.

969b51acb6 flvmux: Don't time out in live mode if no timestamped next buffer is available
But also don't wait for a buffer on both pads, which might take forever in case
of gaps in one of the streams.

The muxer can only advance the time if it has a timestamped buffer that can be
output, otherwise it will just busy-wait and use up a lot of CPU.
