* FFHWAccel: add buffer_ref argument to start_frameLynne2025-03-171-0/+1
| | | | | | | | This commit adds a reference to the buffer as an argument to start_frame, and adapts all existing code. This allows for asynchronous hardware accelerators to skip copying packet data by referencing it.

* avcodec/mpegpicture: Split MPVPicture into WorkPicture and ordinary PicAndreas Rheinhardt2024-06-121-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two types of MPVPictures: Three (cur_pic, last_pic, next_pic) that are directly part of MpegEncContext and an array of MPVPictures that are separately allocated and are mostly accessed via pointers (cur|last|next)_pic_ptr; they are also used to store AVFrames in the encoder (necessary due to B-frames). As the name implies, each of the former is directly associated with one of the _ptr pointers: They actually share the same underlying buffers, but the ones that are part of the context can have their data pointers offset and their linesize doubled for field pictures. Up until now, each of these had their own references; in particular, there was an underlying av_frame_ref() to sync cur_pic and cur_pic_ptr etc. This is wasteful. This commit changes this relationship: cur_pic, last_pic and next_pic now become MPVWorkPictures; this structure does not have an AVFrame at all any more, but only the cached values of data and linesize. It also contains a pointer to the corresponding MPVPicture, establishing a more natural relationsship between the two. This already means that creating the context-pictures from the pointers can no longer fail. What has not been changed is the fact that the MPVPicture* pointers are not ownership pointers and that the MPVPictures are part of an array of MPVPictures that is owned by a single AVCodecContext. Doing so will be done in a latter commit. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/avcodec: Add FFHWAccel, hide internals of AVHWAccelAndreas Rheinhardt2023-08-071-15/+16
| | | | | | | | | This commit is the AVHWAccel analogue of commit 20f972701806be20a77f808db332d9489343bb78: It moves the private fields of AVHWAccel to a new struct FFHWAccel extending AVHWAccel in an internal header (namely hwaccel_internal.h).

| * lavc: external hardware frame pool initializationwm42017-10-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | This adds a new API, which allows the API user to query the required AVHWFramesContext parameters. This also reduces code duplication across the hwaccels by introducing ff_decode_get_hw_frames_ctx(), which uses the new API function. It takes care of initializing the hw_frames_ctx if needed, and does additional error handling and API usage checking. Support for VDA and Cuvid missing.
