* avcodec/mpegvideo: Move fields to {H263Dec,MPVEnc}Context when possibleAndreas Rheinhardt2025-07-031-1/+1
| | | | Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/h263dec: Stop using MpegEncContext.gbAndreas Rheinhardt2025-07-031-4/+4
| | | | | | | | Add a GetBitContext to H263DecContext instead. This is in preparation for removing MpegEncContext.gb. Also move last_resync_gb to H263DecContext. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/h263dec: Add H263DecContextAndreas Rheinhardt2025-07-031-1/+1
| | | | | | | | | This is in preparation for moving the fields only used by H.263-based decoders from MPVContext to H263DecContext. For now only the decode_mb function pointer has been moved (to be able to switch said callback to use an H263DecContext*). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/mpegvideo: Move [fb]_code to Mpeg4Dec and MPVEncContextAndreas Rheinhardt2025-05-161-2/+2
| | | | | | | | It is only used by the MPEG-4 decoder and the encoders. Notice that this field is a per-frame property and therefore does not need to by synced in mpeg4_update_thread_context(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* FFHWAccel: add buffer_ref argument to start_frameLynne2025-03-171-1/+4
| | | | | | | | 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/mpegvideo: Move quant_precision to Mpeg4DecContextAndreas Rheinhardt2024-06-201-1/+1
| | | | | | | | It is an MPEG-4-only value; it is always five for the MPEG-4 encoder, so just hardcode this value and move the MpegEncContext field to Mpeg4DecContext. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpegpicture: Split MPVPicture into WorkPicture and ordinary PicAndreas Rheinhardt2024-06-121-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/mpegvideo: Shorten variable namesAndreas Rheinhardt2024-06-121-7/+7
| | | | | | | | current_picture->cur_pic, last_picture->last_pic, similarly for new_picture and next_picture. Also rename the corresponding *_ptr fields. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/avcodec: Add FFHWAccel, hide internals of AVHWAccelAndreas Rheinhardt2023-08-071-10/+10
| | | | | | | | | 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).

* avcodec/hwconfig: Move HWACCEL_CAP_* to a new headerAndreas Rheinhardt2023-08-071-1/+1
| | | | | | | | | | | | | | libavcodec/hwconfig.h currently contains HWACCEL_CAP_* flags as well as the definition of AVCodecHWConfigInternal and some macros to create them. The users of these two are nearly disjoint: The flags are used by files providing AVHWAccels whereas AVCodecHWConfigInternal is used by files providing codecs (for FFCodec.hw_configs). This patch therefore moves these flags to a new file hwaccel_internal.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| * lavc: external hardware frame pool initializationwm42017-10-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| * pthread_frame: do not run hwaccel decoding asynchronously unless it's safeAnton Khirnov2016-12-191-0/+3
| | | | | | | | | | | | | | | | | | | | Certain hardware decoding APIs are not guaranteed to be thread-safe, so having the user access decoded hardware surfaces while the decoder is running in another thread can cause failures (this is mainly known to happen with DXVA2). For such hwaccels, only allow the decoding thread to run while the user is inside a lavc decode call (avcodec_send_packet/receive_frame).

| | | | | | | | | | | | | | | | | | | | | | | | Move libavcodec managed objects from the public struct vaapi_context to a new privately owned FFVAContext. This is done so that to clean up and streamline the public structure, but also to prepare for new codec support, thus requiring new internal data to be added in there. The AVCodecContext.hwaccel_context, that holds the public vaapi_context, shall no longer be accessed from within vaapi_*.c codec support files.

| | | | | | | | | | | | | | | | | | | | | | When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.
