* avutil/hwcontext_vdpau: Map 444 pix fmts to new VdpYCbCr typesManojGuptaBonda2019-05-05
| | | | | | | | | | New VdpYCbCr Formats VDP_YCBCR_FORMAT_Y_U_V_444 and, VDP_YCBCR_FORMAT_Y_UV_444 have been added in VDPAU with libvdpau-1.2 to be used in get/putbits for YUV 4:4:4 surfaces. Earlier mapping of AV_PIX_FMT_YUV444P to VDP_YCBCR_FORMAT_YV12 is not valid. Hence this Change maps AV_PIX_FMT_YUV444P to VDP_YCBCR_FORMAT_Y_U_V_444 to access the YUV 4:4:4 surface via read-back API's of VDPAU.

| * time_internal: Prefix fallback versions of gmtime_r/localtime_r with ff_Martin Storsjö2019-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Use a macro to redirect calling code from the official name to the ff_ prefixed one. Detecting these functions in configure can be tricky (on mingw, they are conditionally available depending on posix feature defines). If configure didn't detect them, but they still are visible at compile time (due to an unrelated header defining the posix feature defines), providing the local fallback versions with a prefixed name is safer.

* | avcodec/videotoolbox: add support for 10bit pixel formatfumoboy0072019-04-16
| | | | | | | | | | this patch was originally posted on issue #7704 and was slightly adjusted to check for the availability of the pixel format.
* | libavutil/hwcontext_opencl: Fix channel order in format support checkJarek Samic2019-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | The `opencl_get_plane_format` function was incorrectly determining the value used to set the image channel order. This resulted in all RGB pixel formats being set to the `CL_RGBA` pixel format, regardless of whether or not they actually *were* RGBA. This patch fixes the issue by using the `offset` and depth of components rather than the loop index to determine the value of `order`.

* | avutil/hcontext_cuda: Remove unnecessary stream synchronisationPhilip Langdale2019-03-30
| | | | | | | | | | | | | | Similarly to the previous changes, we don't need to synchronise after a memcpy to device memory. On the other hand, we need to keep synchronising after a copy to host memory, otherwise there's no guarantee that subsequent host reads will return valid data.
* | lavu/opencl: replace va_ext.h with standard nameRuiling Song2019-03-22
| | | | | | | | | | | | | | | | | | Khronos OpenCL header (https://github.com/KhronosGroup/OpenCL-Headers) uses cl_va_api_media_sharing_intel.h. And Intel's official OpenCL driver for Intel GPU (https://github.com/intel/compute-runtime) was compiled against Khronos OpenCL header. So it's better to align with Khronos.

| | | | | | | | | | | | | | | | | | The function typedefs we were using are only present when using the dynamic loader, which means compilation breaks for code directly using the cuda SDK. To fix this, let's just duplicate the function typedefs locally. These are not going to change.

| | | | | | | | | | | | | | | | | | | | | | | | As .rodata isn't one of the default created sections for COFF, it was created as a read-write data section.

* | avutil: add ROI (Region Of Interest) data struct and bump versionGuo, Yejun2019-01-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The encoders such as libx264 support different QPs offset for different MBs, it makes possible for ROI-based encoding. It makes sense to add support within ffmpeg to generate/accept ROI infos and pass into encoders. Typical usage: After AVFrame is decoded, a ffmpeg filter or user's code generates ROI info for that frame, and the encoder finally does the ROI-based encoding. The ROI info is maintained as side data of AVFrame. Signed-off-by: Guo, Yejun <yejun.guo@intel.com> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
