640a65bf96 gst: don't use volatile to mean atomic
volatile is not sufficient to provide atomic guarantees and real atomics
should be used instead.  GCC 11 has started warning about using volatile
with atomic operations.

824b0ce0f4 Revert "d3d11: Enable native multi-thread protection layer and make use of it"
This reverts commit 872b7f503c.

Native multi-thread protection layer seems to be consuming more CPU
resource than application side protection approach in some cases

872b7f503c d3d11: Enable native multi-thread protection layer and make use of it
... instead of our own GRecMutex locking. In this way, any other
Direct3D11 client (MediaFoundation for example) can safely call
any Direct3D11 API even when we are sharing our Direct3D11 device
with others.

... instead of QueryInterface-ing per elements. Note that
ID3D11VideoDevice and ID3D11VideoContext objects might not be available
if device doesn't support video interface.
So GstD3D11Device object will create those objects only when requested.

a6b5e3c7d5 transcoder: Add state-changed signal
Similar to GstPlayer, a new signal for state tracking is now emitted at runtime,

12a7bf9f7c player: Rewrite as GstPlay wrapper
For the time being the GstPlayer library remains as a wrapper for GstPlay, in
order to keep existing applications working and give them time to port to
GstPlay. GstPlayer will remain in -bad for a couple cycles and the plan for
GstPlay is to move it to -base before 1.20.

a74651ddc1 play: Introducing the new playback library
This aims to be a replacement for the GstPlayer library. In GstPlay, notifications are
sent as application messages through a dedicated GstBus. The GMainContext-based
signal dispatcher was replaced by a GObject signal adapter, now relying on the
bus to emit its signals. The signal dispatcher is now optional and fully
decoupled from the GstPlay object.

8c2fd4fff7 transcoder: Rework the API to create/get SignalAdapter
We can only have 1 single GstTranscoderSignalAdapter object for a
given GstTranscoder object, this enforces that by avoiding to expose
a constructor and instead add a method to GstTranscoder to get the
signal adapter (internally creating it when needed). We can still
cleanly ensure that the signal adapter is running for the requested
GMainContext and return NULL if it is not the case.

636a77a83f codecs: mpeg2decoder: Move frame_unref to handle_frame.
In the current code, we call frame_unref only when the frame is
outputted. This is OK for normal playback, but when seek happens,
the frames stored in DPB is not outputted and causes some memory
leak.
The correct way is that we should call frame_unref every time we
finish the handle_frame(), which is also the behaviour of H264/H265
decoder.

86e312c1b1 codecs: h264decoder: Add support for output delay
Some decoding APIs support delayed output or a command for decoding
a frame doesn't need to be sequential to corresponding command for
getting decoded frame. For instance, subclass might be able to
request decoding for multiple frames and then get for one (oldest)
decoded frame or so.
If aforementioned case is supported by specific decoding API,
delayed output might show better throughput performance.

* Don't warn for live object, since ID3D11Debug itself seems to be
  holding refcount of ID3D11Device at the moment we called
  ID3D11Debug::ReportLiveDeviceObjects(). It would report live object
  always
* Device might not be able to support some formats (e.g., P010)
  especially in case of WARP device. We don't need to warn about that.
* gst_d3d11_device_new() can be used for device enumeration. Don't warn
  even if we cannot create D3D11 device with given adapter index therefore.
* Don't warn for HLSL compiler warning. It's just noise and
  should not be critical thing at all

41d2edc964 codecs: mpeg2decoder: Creating the field based on its arriving time.
Spec says:
In a frame picture top_field_first being set to ‘1’ indicates that the
top field of the reconstructed frame is the first field output by the
decoding process. top_field_first being set to ‘0’ indicates that the
bottom field of the reconstructed frame is the first field output by
decoding process.

Here, the "output" should be interpreted just as the output order, not
including the decoding order. The field should be decoded as the order
they comes in the stream. Namely, no matter top_field_first is 0 or 1,
the first coming field is the first one to be decoded.
