It cleans up videoFormat by combining the wl_shm_formats and
drm_formats into a single table that represents the same format.
In addition, it adds NV61 format to the waylandsink.
commit 6adfb120ab added this flag to fix
builds with `-Werror`, and afterwards it was changed to use a version
check when newer versions of openexr moved over to C++11.
However, some distros have backported patches to older openexr
versions which make it require C++11, which makes the version check
incorrect and causes an error because we passed `-Werror -std=c++98`.
Instead, directly check when usage of the header requires `-std=c++98`
with `-Werror` and override the `cpp_std` setting on the target.

Includes a new GstVulkanHandlePool base class for pooling different
resources togther. The descriptor cache object is ported to
GstVulkanHandlePool with the exact same functionality.
A new GstVulkanFenceCache is also implemented for caching fences
which is used internally by GstVulkanDevice for creating or reusing
fences.
The existing GstVulkanTrashFenceList object now caches trash objects.
Part 1 is a base class (vkvideofilter) that handles instance, device,
queue retrieval and holding that has been moved to the library
Part 2 is a fullscreenrenderquad that is still in the plugin that
performs all of the previous vulkan-specific functionality.
Based on Stream ID, the application can accept or reject the connection,
select the desired data stream, or set an appropriate passphrase for the
connection. Example usage:
srt://127.0.0.1:1234?streamid=mystream
Current code would change any non-ok return from gst_pad_push to
GST_FLOW_ERROR, thus hiding meaningful returns such as GST_FLOW_EOS.
Tests also added.
Most of avtpcvfdepay messages are currently logged as warnings, which can
make some scenarios - such as receiving two AVTP streams on the same
pipeline - too verbose.
This patch tones those message down to INFO or DEBUG level - more in
sync with avtpaafdepay logging.
To allow curlhttpsrc to support DASH streams that use the on-demand
profile, it needs to support HTTP Range GETs. In GStreamer, the RANGE
is specified by issuing a GST_FORMAT_BYTES seek to set the start and
end of the range. curlhttpsrc needs to implement seek and set the
appropriate curl options to make it add the Range header to the
request.
The major functionality gain this provides is proper reference counting
for a descriptor set. Overall this allows us to create descriptor sets
when they are needed (or reused from a cache) without violating any of
vulkan's object synchronisation requirements.
As there are a fixed number of sets available in a pool, the number of
descriptors in elements is currently hardcoded to 32. This can be extended
in a future change to create pools on the fly if that limit is ever overrun.
Allows a cleaner control flow when there is no fence available for use
with the trash list. An always signalled fence type will always return
TRUE for gst_vulkan_fence_is_signalled.
The following build error occurs:
vkdeviceprovider.h:30:10: fatal error: gst/vulkan/vulkan.h: No such file or directory

By passing NULL to `g_signal_new` instead of a marshaller, GLib will
actually internally optimize the signal (if the marshaller is available
in GLib itself) by also setting the valist marshaller. This makes the
signal emission a bit more performant than the regular marshalling,
which still needs to box into `GValue` and call libffi in case of a
generic marshaller.
Note that for custom marshallers, one would use
`g_signal_set_va_marshaller()` with the valist marshaller instead.
It provides to set tile-columns and tile-rows configurations. The av1
codec allows an input image frame be partitioned into separate vertical
or horizontal tile which can be encoded or decoded independently. It
helps to encode/decode parallel.
CURLOPT_DEBUGFUNCTION option replaces the standard debug function
used when CURLOPT_VERBOSE is in effect. This callback receives various debug information.
And only update the caps and stream-start event accordingly. This
ensures that we'll always forward sticky events that arrive after the
caption pad was created, and especially updates to existing sticky
events like the segment event.
Also create a proper stream id based on the upstream stream id for the
stream-start event, and make sure that all the sticky events we know are
already on the caption pad at the time it is added to the element.
clamp-to-border will return the border color which is typically black,
white or transparent. When linear filtering the edge pixels will
typeically be combined with the border color which is not typically what
we want. Especially when color converting, this removes a green box
around the edge when converting YUV->RGB.
This fixes a regression from commit "srtp: Support libsrtp2"
e9aa117200 where an internal
set of ssrc(s) was added because the libsrtp v2 keeps its
internal streams as private. But the change prevented that
ssrc(s) that not in the caps from being added to the stats.
This patch ensures that all ssrc(s) are inserted to this set
instead of only inserting those from the caps.
If the mutex is locked while running frameComplete there is a potential deadlock
bound to happen when we get a new exported images from the backend.
Fixes#1101
hlssink2 defined "max-files" property to decide the maximum number
of fragments which should be stored in disk. But we've not used
the property. Instead, the size has been maintained by "playlist-length".
Since "max-files" and "playlist-length" have different meaning,
the decision should be done by "max-files" property.
For example, an user might want expose only 3 fragments via playlist
but might want to keep more files than 3 in disk.
A classic case of not updating the next item to iterate after deleting
it from the singly linked list.
Only ever hit with a text buffer with GST_CLOCK_TIME_NONE for either the
timestamp or duration.
hlssink* elements could be finalized without EOS event, and in that case
the final playlist might not include the EXT-X-ENDLIST tag.
Since missing ENDLIST tag means it's live stream, but we did't intend it,
hlssink* elements should put the tag at the end.
In Debian, soundfonts in SF3 format (i.e. the same as SF2 format but
with Ogg/Vorbis-compressed samples) are installed into
/usr/share/sounds/sf3. Soundfonts in SF3 format are supported since
FluidSynth 1.1.7 (released in Feb 2018).
Internal sources seem to be rtp streams we are sending whereas
non-internal sources are the rtp streams we are receiving. Redo the
statistics with that in mind.
This reverts commit 68fa80e831.
Some wayland servers, especially weston, only expect empty input
region as a request to disable input.

The function _get_stats_from_ice_transport returns a string which must be
freed by the caller. However, _get_stats_from_dtls_transport was ignoring
the return value from this function, resulting in a leak.
Ran this with valgrind. Before this fix there was a leak of 40 bytes each
time this was called. After there was no leak.

_decrypt_start() failure will lead to decryption failure eventually
but catching it earlier if possible. The decrpytion start failure means
that the hls plugin was built without crypto library or crypto library
does not want to accept given key and IV.
crypto libraries are not required for hlssink and hlssink2.
Also, hlsdemux with nonencrypted stream can work without crpyto.
Make an error only when users set "hls-crpyto" with non-auto option explicitly,
but no crpyto library was found.
On Windows, if libusrsctp and gstreamer are built with different
C runtimes (CRT), we cannot free memory allocated inside libusrsctp
with the `free()` function from gstreamer's CRT.
`usrsctp_freedumpbuffer()` simply calls `free()`, but because of the
way DLLs work on Windows, it will always call the free function from
the correct CRT.
