Andreas Rheinhardt	fe6037fd04	avcodec/mpegpicture: Split MPVPicture into WorkPicture and ordinary Pic 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>	7 months ago
Andreas Rheinhardt	ec1eba792a	avcodec/mpegvideo: Shorten variable names 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>	7 months ago
Aleksoid	336d59643a	avcodec/d3d12va_vc1: add support for D3D12_VIDEO_DECODE_PROFILE_VC1_D2010 guid. The VC1_D2010 profile, also known as VC1_VLD2010, has the same functionality and specification as the VC1_D profile. Support for this profile serves only as a positive indication that the accelerator has been designed with awareness of the modifications specified in the August 2010 version of this specification. Hardware accelerator drivers that expose support for this profile must not also expose the previously specified VC1_D GUID, unless the accelerator works properly with existing software decoders that use VC1_D and that do not incorporate the corrections added to the August 2010 version of this specification. As a result, we could give VC1_VLD2010 a higher priority and initialize it first. Signed-off-by: Aleksoid <Aleksoid1978@mail.ru> Signed-off-by: Tong Wu <tong1.wu@intel.com>	11 months ago
