* 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 a flag for automatically growing the FIFO as neededAnton Khirnov2022-02-07
| | | | | This will not increase the FIFO beyond 1MB, unless the caller explicitly specifies otherwise.
* 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/frame: Add Dolby Vision metadata side data typeNiklas Haas2022-01-04
| | | | | | | | | | | 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. The precedent for this style of access is set in <libavutil/detection_bbox.h> Signed-off-by: Niklas Haas <git@haasn.dev> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat: introduce AVFormatContext io_close2 which returns an intMarton Balint2021-12-12
| | | | | | | | | | | | | | | | | Otherwise there is no way to detect an error returned by avio_close() because ff_format_io_close cannot get the return value. Checking the return value of the close function is important in order to check if all data was successfully written and the underlying close() operation was successful. It can also be useful even for read mode because it can return any pending AVIOContext error, so the user don't have to manually check AVIOContext->error. In order to still support if the user overrides io_close, the generic code only uses io_close2 if io_close is either NULL or the default io_close callback.

* avformat/avio{,buf}: introduce public AVIOContext::bytes_{read,written}Jan Ekström2021-10-24
| | | | | | | Such fields can be seen as generally useful in cases where the API user is not implementing custom AVIO callbacks, but still would like to know if data is being read or written out, such as in case data is being read from input but no AVPacket has been received yet.
* avformat/avio{,buf}: deprecate AVIOContext::writtenJan Ekström2021-10-24
| | | | | | | | Originally added as a private entry in commit 3f75e5116b900f1428aa13041fc7d6301bf1988a, but its grouping with the comment noting its private state was missed during merging of the field from Libav (most likely due to an already existing field in between).
* lavu/pix_fmt: add pixel format for x2bgr10Manuel Stoeckl2021-09-26
| | | | | | | | | | | The new format (given in big/little endian forms) matches the existing X2RGB10 format, except with B and R channels switched. AV_PIX_FMT_X2BGR10 data often is created by OpenGL programs whose buffers use the GL_RGB10 internal format.

| | | | | | | | | | It is supported only by a few decoders (h263, h263p, mpeg(1|2|)video and mpeg4) and is entirely redundant with parsers. Furthermore, using it leads to missing frames, as flushing the decoder at the end does not work properly.

* 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.

HDR10+ should be passed to packet side data an stored in the container (mkv) for VP9. This CL is taking HDR10+ from AVFrame side data in libvpxenc and is passing it to the AVPacket side data.
