* 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.

* avutil/mem: Deprecate av_mallocz_array()Andreas Rheinhardt2021-09-20
| | | | | | | | It does the same as av_calloc(), so one of them should be removed. Given that av_calloc() has the shorter name, it is retained. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* lavc: deprecate AV_CODEC_(FLAG|CAP)_TRUNCATEDAnton Khirnov2021-09-20
| | | | | | | | | | 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>

* avutil/opt: Document actual behaviour of av_opt_copy a bit moreAndreas Rheinhardt2021-08-17
| | | | | | | | | In particular, document that av_opt_copy() always disentangles allocated options even on error; this guarantee is needed to e.g. properly free duplicated thread contexts in libavcodec on error.

* 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.

* avutil/common, macros: Move several macros from common.h to macros.hAndreas Rheinhardt2021-07-29
| | | | | | | | | | | | common.h currently contains several things: Math macros, UTF-8 macros, other fundamental macros; furthermore it also contains miscellaneous math functions and it (directly and indirectly) includes lots of other headers. This commit moves the "other fundamental macros" to macros.h which is a more fitting place. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec: Pass HDR10+ metadata to packet side data in VP9 encoderMohammad Izadi2021-06-24
| | | | | | | | | | | | | HDR10+ metadata is stored in the bit stream for HEVC. The story is different for VP9 and cannot store the metadata in the bit stream. 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.

* lavc: rename AV_CODEC_CAP_AUTO_THREADS->AV_CODEC_CAP_OTHER_THREADSAnton Khirnov2021-03-16
| | | | | | | | | | This cap is currently used to mark multithreading-capable codecs that wrap external libraries with their own multithreading code. The name is highly confusing for our API users, since libavcodec ALWAYS handles thread_count=0 (see commit message in previous commit). Therefore rename the cap and update its documentation to make its meaning clear. The old name is kept deprecated until next+1 major bump.
