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	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
