* avcodec/vp8, vp9: Avoid using VP56mv and VP56Frame in VP8/9Andreas Rheinhardt2022-07-28
| | | | | | | | | | | | | | | | | | | | | | | | Instead replace VP56mv by new and identical structures VP8mv and VP9mv. Also replace VP56Frame by VP8FrameType in vp8.h and use that in VP8 code. Also remove VP56_FRAME_GOLDEN2, as this has only been used by VP8, and use VP8_FRAME_ALTREF as replacement for its usage in VP8 as this is more in line with VP8 verbiage. This allows to remove all inclusions of vp56.h from everything that is not VP5/6. This also removes implicit inclusions of hpeldsp.h, h264chroma.h, vp3dsp.h and vp56dsp.h from all VP8/9 files. (This also fixes a build issue: If one compiles with -O0 and disables everything except the VP8-VAAPI encoder, the file containing ff_vpx_norm_shift is not compiled, yet this is used implicitly by vp56_rac_gets_nn() which is defined in vp56.h; it is unused by the VP8-VAAPI encoder and declared as av_unused, yet with -O0 unused noninline functions are not optimized away, leading to linking failures. With this patch, said function is not included in vaapi_encode_vp8.c any more.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* lavc/vp9: fix reference frame dimensions check for SINGLE_REFERENCE modeLinjie Fu2020-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | With the description in frame size with refs semantics (SPEC 7.2.5), it is a requirement of bitstream conformance that for at least one reference frame has the valid dimensions. Modify the check to make sure the decoder works well in SINGLE_REFERENCE mode that not all reference frames have valid dimensions. Check and error out if invalid reference frame is used in inter_recon. One of the failure case is a 480x272 inter frame (SINGLE_REFERENCE mode) with following reference pool: 0. 960x544 LAST valid 1. 1920x1088 GOLDEN invalid, but not used in single reference mode 2. 1920x1088 ALTREF invalid, but not used in single reference mode 3~7 ...

* vp9: move VP9SharedContext back to the top of VP9ContextHendrik Leppkes2017-09-19
| | | | | | | | VP9SharedContext needs to be the first member so its properties can be safely accessed from hardware accelerators, without the need to share the full VP9Context. Fixes ticket #6674.

* vp9: split out generic decoding skeleton interface API from VP9 types.Ronald S. Bultje2017-03-28
| | | | | This allows vp9dsp.h to only include the VP9 types header, and not the decoder skeleton interface which is for hardware decoders (dxva2/vaapi).

* vp9: re-split the decoder/format/dsp interface header files.Ronald S. Bultje2017-03-28
The advantage here is that the internal software decoder interface is not exposed to the DSP functions or the hardware accelerations.
