* libavutil/hwcontext_d3d11va: adding more texture information to the D3D11 ↵Artem Galin2021-09-08
| | | | | | | | | | | | hwcontext API Microsoft VideoProcessor requires texture with D3DUSAGE_RENDERTARGET flag as output. There is no way to allocate array of textures with D3D11_BIND_RENDER_TARGET flag and .ArraySize > 2 by ID3D11Device_CreateTexture2D due to the Microsoft limitation. Adding AVD3D11FrameDescriptors array to store array of single textures instead of texture with multiple slices resolves this. Signed-off-by: Artem Galin <artem.galin@intel.com>
* libavutil/hwcontext_qsv: add usage child_device_type argument to explicitly ↵Artem Galin2021-09-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | select d3d11va/DX11 device type UPD: Rebase of last patch set over current master and use DX9 as default device type. Makes selection of dxva2/DX9 device type by default as before with explicit d3d11va/DX11 usage to cover more HW configurations. Added warning message to expect changing default device type in the future. Fixes TGL / AV1 decode as requires DX11 with explicit DX11 type selection. Add headless/multi adapter support and fixes: https://trac.ffmpeg.org/ticket/7511 https://trac.ffmpeg.org/ticket/6827 http://ffmpeg.org/pipermail/ffmpeg-trac/2017-November/041901.html https://trac.ffmpeg.org/ticket/7933 https://github.com/InitialForce/FFmpeg/commit/338fbcd5bba1de0e1b3e3bad8985eee2fdfbeca1 https://github.com/jellyfin/jellyfin/issues/2626#issuecomment-602153952 Any other fixes are welcome including OpenCL interop patch since I don't have proper setup to validate this use case Decoding, encoding, transcoding have been validated. child_device_type option is responsible for d3d11va/dxva2 device selection Usage examples: DirectX 11: -init_hw_device qsv:hw,child_device_type=d3d11va -init_hw_device qsv:hw,child_device_type=d3d11va,child_device=0 OR -init_hw_device d3d11va=dx -init_hw_device qsv@dx DirectX 9 is still supported but requires explicit selection: -init_hw_device qsv:hw,child_device_type=dxva2 OR -init_hw_device dxva2=dx -init_hw_device qsv@dx Signed-off-by: Artem Galin <artem.galin@intel.com>

* avformat/matroskaenc: Pass dispositions through unchanged by defaultAndreas Rheinhardt2021-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now, the Matroska muxer did not use the dispositions it is given as-is; instead it by default overrode the disposition of the first track of a kind (audio, video, subtitles) if no track of this kind has the default disposition set. And up until recently, it also enforced by default that no more than one track of each kind be marked as default. The rationale for the former is that there are lots of containers which lack the concept of default streams, so that it is not uncommon for no stream to be marked as default at all; the rationale for the latter was that up until recently, it was dubious whether the Matroska specification allowed more than one default stream for track type (e.g. mkvmerge disallowed it). It was this point which led to the implementation of the above mentioned behaviour inspired by mkvmerge. Yet the Matroska specifications have changed and now explicitly allow to set more than one track of each type as default, so that the main reason of not using the dispositions as-is was rendered moot. Therefore this commit changes the default to pass the disposition through. The matroska-mpegts-remux FATE-test has been updated to still use the old "infer" mode so that it is still covered by FATE; the matroska-zero-length-block test has also been updated to cover the infer_no_subs mode. The references for lots of other FATE tests needed to be updated because of a newly added FlagDefault element with value zero (whereas a FlagDefault with value 1 needn't be coded at all, as it coincided with the default value of said element).

* avformat/matroskaenc: Allow to set multiple streams as defaultAndreas Rheinhardt2021-08-24
| | | | | | | | | | The Matroska specifications have evolved and now allow to mark multiple tracks of the same kind as default (whether this was legal or not before was dubious; e.g. mkvmerge disallowed it). Yet when the Matroska muxer is set to infer default dispositions if absent, it also enforced the now outdated restriction. So update this.

* imgutils: expose av_image_copy_plane_uc_from()Lynne2021-08-14
| | | | | | | | | | | | The reason why the generic av_image_copy_uc_from() doesn't really fit in the case for Vulkan is because some planes may be copied via other methods (such as mapping GPU memory), and if they don't satisfy the strict alignment requirements, a gpu image->gpu buffer->cpu ram copy is performed. We need this for hwcontext_vulkan, and I think this will also be useful to API users like libplacebo who would rather not write a custom SIMD memcpy.
