When receiving an instant-rate-change event, store the updated
seek flags and replace the flags in any input segments with them
to allow for instant switching between trickmodes and not.

It's possible that a buffer might be within the segment proper,
but not within the "valid" part we're playing, which is only
things after the 'offset' part of the segment. In that case,
the running-times of the buffer-start and buffer-stop will be
GST_CLOCK_TIME_NONE, and we'd better not schedule playback that
far in the future.
This commit modifies GstVideoMasteringDisplayInfo and GstVideoContentLightLevel
structs so that each value is to be more like hdr_metadata_infoframe struct
of linux drm header and DXGI_HDR_METADATA_HDR10 struct of Windows.
So each value is no more fraction but normalized one as per CTA 861.G spec.
Also the unit of each value will be consistent with H.264, H.265
specifications, hdr_metadata_infoframe struct for linux and
DXGI_HDR_METADATA_HDR10 struct for Windows.

Because the color value is stored in MSB, so we can reuse the
Y210 code for P012_LE / P012_BE
Sample pipeline:
gst-launch-1.0 videotestsrc ! video/x-raw,format=Y212_LE ! glimagesink
This can be used to have compositor display either the background
or a stream on a lower zorder after a live input stream freezes
for a certain amount of time, for example because of network
issues.
gst_gl_window_quit() will attempt to send a message but will be called
from GstGLContext's finalize handler and so the weak ref that backs
gst_gl_window_get_context will return NULL as it has already been
cleared. We need that context in send_message_async to decide whether
to run the provided callback immediately or queue in GCD
Without this fix, it is possible that outbuf is not initialized, which
will result in segfault when call gst_buffer_replace (&outbuf, NULL). In
addition, the patch fixes potential memory leak in restart path.
The segfault can be reproduced by the pipeline below:
GST_GL_PLATFORM=egl \
gst-launch-1.0 videotestsrc ! msdkh265enc ! msdkh265dec ! \
'video/x-raw(memory:DMABuf)' ! glimagesink
In the situation that the direct dmabuf path is chosen, but with an
unsupported texture format, this causes accept to fail rather than
continue and fail at the upload stage. It is also possibly necessary to
reconfigure after falling back from direct to non-direct dmabuf upload
paths.
The wordlen ("length") MUST represent the total "number of 32-bit words
in the extension, excluding the four-octet extension header" (rfc3550).
There are cases where already existent padding is reused for adding
the new extension. So the new wordlen should be updated if the new
added extension makes it to increase.
This patch introduces a new API to send and parse mouse scroll events. Mouse
event coordinates are sent relative to the display space of the related output
area. This is usually the size in pixels of the window associated with the
element implementing the GstNavigation interface.
This patch introduces a property which, if set to FALSE, prevents RTP
basepayloader from scaling the RTP time when a segment's rate is not
equal to 1.0. The specification is ambiguous on this subject and some
clients expect the timestamps not to be scaled.
This allows us to remove races when setting the wl_queue on wayland
objects with wl_proxy_set_queue() as each created object is created with
the queue already set.
We can also move all our initilization code into the window as we
can retrieve all wayland objects from each window instance. This
removes a possible race when integrating with external API's as we would
always attempt to immediately retrieve a small set of wayland objects.
That is no longer the case with the objects from each window instance.
Automatic negotiation of texture-target=external-oes does not work
without separating the external-oes support out of the DirectDmabuf
uploader into a separate DirectDmabufExternal uploader.
gst_gl_upload_transform_caps() is missing a NULL pointer check in case
the current upload method's transform_caps returns a NULL pointer. In
the following loop over all upload methods, NULL pointer return values
are already handled correctly.
Some drivers support directly importing DMA buffers in some formats into
external-oes textures only, for example because the hardware contains
native YUV samplers.
Note that in these cases colorimetry can only be passed as hints and
there is no feedback whether the driver supports the required YUV
encoding matrix and quantization range.
Allow creating EGL images from DMA buffers in formats that the driver
only supports for the external-oes texture target.
Pass the intended texture target to gst_egl_image_from_dmabuf_direct so
that _gst_egl_image_check_dmabuf_direct can decide whether to create an
EGL image for a format that can only be targeted at external-oes
textures by the driver. Allow creating GstGLMemoryEGL objects from these
DMA buffers.
