to have timecode metas. The original use case is to serialize
closed captions extracted from a video stream, in that case
ccextractor copies the video time code metas to the closed
caption buffers, but no such mechanism exists when creating

For the consent freshness functionality (RFC 7675) to work the ICE

This encoder advertises alignment=au as output format, which means
each output frame should contain a full decodable access unit.

The video encoder base class is not aware of our output alignment
and will output spurious buffers with just the SPS/PPS inside when
we call gst_video_encoder_set_headers(), which is broken because
each buffer is supposed to contain a full decodable access unit
in our case.

Just don't tell the base class about our headers, they will be
sent at the beginning of each IDR frame anyway.

Since d3d11 implementation is a candidate for public library in the future,
we need to hide everything from header as much as possible.

Note that the total size of allocated d3d11 texture memory by GPU is not
controllable factor. It depends on hardware specific alignment/padding
requirement. So, GstD3D11 implementation updates actual buffer size

memory size without allocating real D3D11 texture.
