Lynne	9db68ed042	hw_base_encode: refactor picture allocation/freeing ... This commit cleans up and refactors the mess of private state upon private state that used to be. Now, FFHWBaseEncodePicture is fully initialized upon call-time, and, most importantly, this lets APIs which require initialization data for frames (VkImageViews) to initialize this for both the input image, and the reconstruction (DPB) image.

Tong Wu	b1d410716b	lavc/d3d12va_encode: trim header alignment at output ... It is d3d12va's requirement that the FrameStartOffset must be aligned as per hardware limitation. However, we could trim this alignment at output to reduce coded size. A aligned_header_size is added to D3D12VAEncodePicture.

Tong Wu	e783e45e29	avcodec/hw_base_encode: avoid getting FFHWBaseEncodeContext from avctx ... This patch is to make FFHWBaseEncodeContext a standalone component and avoid getting FFHWBaseEncodeContext from avctx->priv_data. This patch also removes some unnecessary AVCodecContext arguments. For receive_packet call, a small wrapper is introduced. Signed-off-by: Tong Wu <tong1.wu@intel.com>	2024-07-02 14:15:12 +02:00
