our download thread is later using.

request. However, for any context other than the one that created the
session, this will also create and destroy sources, so there's still

adaptivedemux2: Fix for period switching in live streams

When playing live, it's possible that one stream reaches
the end of the available playback window and goes to sleep
waiting for a manifest update, and the manifest update
introduces a new period. In that case, the sleeping
stream needs to wake up and go 'properly' EOS before we
can advance the input to the new period.

Accordingly, make sure that a stream's last_ret value
is not marked as EOS if it's just sleeping waiting for a live
manifest update.

Also fix the output loop to go back and re-check if it's
time to switch to the next period after dequeuing and
discarding an EOS event.

basetextoverlay: Don't miscalculate text running times

When a new segment event arrives, it immediately updates
the current stored segment, which was used for calculating
the running time of the current text buffer for every
passing video frame. This means a segment that arrives
after the text buffer might get used to (mis)calculate
the running times subsequently.

Instead, calculate and store the right running time
using the current segment when storing the buffer. Later
the stored segment can get freely updated.

This fixes the case where pieces of video and text streams
are seamlessly concatenated and fed through the text overlay.
Previously, it could lead to the current text buffer suddenly
have a massive running time and blocking all further input.

gst: Protect initialization state with a recursive mutex.

Otherwise a gst_init() call from a plugin would deadlock if the plugin
is loaded as part of registry updating.

Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/940

registry: Remove dead code

Initialization/updating of the registry can't possible fail and all code
paths always returned TRUE.

gst: Don't fail gst_init() if updating the registry fails

Everything is already marked as initialized at that point and by failing
no tracers would be loaded or plugin feature rank overrides would be
applied.

videoflip: Add support for 10/12bit planar formats

Implements support for I420, I422 and Y444 in 10/12 bit LE/BE variants.
I422 is handled separately from the rest, as it needs to consider
the endianness of the current format during most transforms.

vah264enc: Set codec frame sync point if IDR

d3d11: Use WIN32 API directly for locking with RAII pattern

Such abstraction is unnecessary for this library/plugin.
Use WIN32 API directly instead of GLib wrappers.

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2848>

d3d11memory: Remove unnecessary locking

* memory map/unmap is already protected by d3d11 device lock.
  Don't need to take another memory lock.
* Use WIN32 critical section and slim reader/writer lock APIs
  directly instead of GLib wrappers.

vah264enc: Fix caps for mesa gallium.

Radeon mesa gallium driver has a bug which adds P010_10LE sink caps
format. This patch removes formats which arent 420 chroma.

gst_caps_set_format_array() wasn't used because the fix traverse
several structures with potential different formats.

vah264dec: Complete profiles in decoder.

Instead of specifying all the H.264 "supported" profiles in the global
hash table (used either by decoders and encoders), just complete them
in the decoder only, since the encoder doesn't support them.

hlsdemux2: Requeue header buffer when restarting fragment

When returning GST_ADAPTIVE_DEMUX_FLOW_RESTART_FRAGMENT
for the first segment data, we might need to requeue the
header.

This was leading to occasional prerolling stalls on
HLS live streams with renditions.

hlsdemux2: Fix buffer leak when resynching

dmabuf: Always skip modifier if it's linear

Accepting both NV12 and NV12:0x0000000000000000 will make the

d3d11: Don't find global default allocator

We were using global default allocator already. Pass null
allocator object to *_alloc() methods then the method will
use default allocator.

d3d11memory: Allow null GstD3D11Allocator to alloc methods

Similar to gst_allocator_alloc(), use default GstD3D11Allocator
when caller passes null allocator object

adaptivedemux2: Fix a small race on shutdown

Make sure gst_adaptive_demux_loop_cancel_call()
never tries to operate on an invalidated main context. Make
sure to clear the main context pointer while holding the lock,
and to check it in gst_adaptive_demux_loop_cancel_call()

d3d11device: Use WIN32 critical section API directly

GLib's GRecMutex will allocate another heap memory for CRITICAL_SECTION
struct and g_rec_mutex_lock/g_rec_mutex_unlock use WIN32 APIs actually.
We don't need such intermediate function calls and redundant heap allocation.
Just call WIN32 APIs directly.

adaptivedemux2/hlsdemux2: Handle loss of sync when dowloading.

Media playlist updates and fragment downloads happen in an interleaved
fashion. When a media playlist update fails *while* a segment is being
downloaded, this means we lost synchronization.

Properly propagate and handle this

hlsdemux2: Fix initial playlist setup.

There is now only a single case where we setup the initial playlist to 0, which
is for the very first variant stream.

Rendition streams will have the initial playlist "synchronized" against the
variant stream media playlist.
