* lavu/pixfmt: add packed RGBA float16 formatTimo Rothenpieler2022-08-13
| | | | | This is the default format of the Windows compositor and what DXGI Desktop Duplication will give you for any kind of HDR output.
* lavu/hwcontext_qsv: add loader field to AVQSVDeviceContextHaihao Xiang2022-08-12
| | | | | | | | | | | In oneVPL, a valid mfxLoader handle is needed when creating mfx session for decoding, encoding and processing[1], so add loader field to AVQSVDeviceContext. User should fill this field before calling av_hwdevice_ctx_init() if using oneVPL This is in preparation for oneVPL support [1]https://spec.oneapi.io/versions/latest/elements/oneVPL/source/programming_guide/VPL_prg_session.html#onevpl-dispatcher
* lavu/hwcontext_vaapi: Map the AYUV formatPhilip Langdale2022-08-03
| | | | This is the format used by Intel VAAPI for 8bit 4:4:4 content.
* lavu/pixfmt: Add packed 4:4:4 formatPhilip Langdale2022-08-03
| | | | | | | | | The "AYUV" format is defined by Microsoft as their preferred format for 4:4:4 content, and so it is the format used by Intel VAAPI and QSV. As Microsoft like to define their byte ordering in little-endian fashion, the memory order is reversed, and so our pix_fmt, which follows memory order, has a reversed name (VUYA).
* lavu/frame: allow calling av_frame_make_writable() on non-refcounted framesAnton Khirnov2022-08-02
| | | | | This is an easy way to make a refcounted frame from a non-refcounted one.
* lavu/frame: add a duration field to AVFrameAnton Khirnov2022-07-19
| | | | | | | | | The only duration field currently present in AVFrame is pkt_duration, which is semantically restricted to those frames that are output by decoders. Add a new field that stores the frame's duration without regard for how that frame was produced. Deprecate pkt_duration.

* avutil/csp: create public API for colorspace structsLeo Izen2022-06-01
| | | | | | | | | | This commit moves some of the functionality from avfilter/colorspace into avutil/csp and exposes it as a public API so it can be used by libavcodec and/or libavformat. It also converts those structs from double values to AVRational to make regression testing easier and more consistent. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* libavutil: Deprecate av_fopen_utf8, provide an avpriv versionMartin Storsjö2022-05-23
| | | | | | | | | | | | | | | | | | | | | | Since every DLL can use an individual CRT on Windows, having an exported function that opens a FILE* won't work if that FILE* is going to be used from a different DLL (or from user application code). Internally within the libraries, the issue can be worked around by duplicating the function in all libraries (this already happened implicitly because the function resided in file_open.c) and renaming the function to ff_fopen_utf8 (so that it doesn't end up exported from the DLLs) and duplicating it in all libraries that use it. This makes the avpriv_fopen_utf8 / ff_fopen_utf8 function work in the exact same way as the existing avpriv_open / ff_open, with the same setup as introduced in e743e7ae6ee7e535c4394bec6fe6650d2b0dbf65. That mechanism doesn't work for external users, thus deprecate the existing function. Signed-off-by: Martin Storsjö <martin@martin.st>

* avutil/channel_layout: Add a new channel layout APIAnton Khirnov2022-03-15
| | | | | | | | | | | | | The new API is more extensible and allows for custom layouts. More accurate information is exported, eg for decoders that do not set a channel layout, lavc will not make one up for them. Deprecate the old API working with just uint64_t bitmasks.

* lavu/pixfmt: deprecate AV_PIX_FMT_XVMCAnton Khirnov2022-02-15
| | | | It is no longer used for anything.
* avutil/fifo: Deprecate old FIFO APIAnton Khirnov2022-02-07
| | | | | | | | Users should switch to the superior AVFifo API. Unfortunately AVFifoBuffer fields cannot be marked as deprecated because it would trigger a warning wherever fifo.h is #included, due to inlined av_fifo_peek2().
* lavu/fifo: Add new AVFifo API based upon the notion of element sizeAnton Khirnov2022-02-07
| | | | | | | | | | | | | | | | | | Many AVFifoBuffer users operate on fixed-size elements (e.g. pointers), but the current FIFO API deals exclusively in bytes, requiring extra complexity in all these callers. Add a new AVFifo API creating a FIFO with an element size that may be larger than a byte. All operations on such a FIFO then operate on complete elements. This API does not reuse AVFifoBuffer and its API at all, but instead uses an opaque struct called AVFifo. The AVFifoBuffer API will be deprecated in a future commit once all of its users have been switched to the new API. Not reusing AVFifoBuffer also allowed to use the full range of size_t from the beginning.

* lavu/fifo: deprecate av_fifo_peek2()Anton Khirnov2022-01-10
| | | | | | It returns a pointer inside the fifo's buffer, which cannot be safely used without accessing AVFifoBuffer internals. It is easier and safer to use av_fifo_generic_peek_at().

| | | | | | | | | | | In order to be able to extend this struct later (as the Dolby Vision RPU evolves), all of the 'container' structs are considered extensible, and the individual constituent fields must instead be accessed via offsets.

* 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>

* 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.
