* avcodec/mips: [loongson] mmi optimizations for VP9 put and avg functionsgxw2019-02-27
| | | | | | | VP9 decoding speed improved about 60.5%(from 38fps to 61fps, tested on loongson 3A3000). Reviewed-by: Shiyou Yin <yinshiyou-hf@loongson.cn> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avutil/cuda_check: Fix non-dynamic-loader implementationPhilip Langdale2019-02-24
| | | | | | | | | 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.

| * arm: Create proper .rdata sections for COFFMartin Storsjö2019-01-25
| | | | | | | | | | | | | | | | | | | | | | | | As .rodata isn't one of the default created sections for COFF, it was created as a read-write data section. By using the default .rdata section name for COFF, it automatically becomes a read-only data section. The existing ".section .rodata" works as intended for ELF though. This is based on an original patch and diagnose by Tom Tan <Tom.Tan@microsoft.com>. Signed-off-by: Martin Storsjö <martin@martin.st>

| * arm: Emit .thumb_func directivesMartin Storsjö2018-10-12
| | | | | | | | | | | | | | | | | | | | | | Prior to Xcode 9.3, the clang built-in assembler didn't support altmacro, and gas-preprocessor was used for assembling for arm/darwin. For thumb functions, gas-preprocessor took care of adding the .thumb_func directives, but when now being able to assemble without gas-preprocessor, we need to add these directives ourselves.

* | 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>

* | lavu/qsv: make a copy as libmfx alignment requirement for uploadingZhong Li2018-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Libmfx requires 16 bytes aligned input/output for uploading. Currently only output is 16 byte aligned and assigning same width/height to input with smaller buffer size actually, thus definitely will cause segment fault. Can reproduce with any 1080p nv12 rawvideo input: ffmpeg -init_hw_device qsv=qsv:hw -hwaccel qsv -filter_hw_device qsv -f rawvideo -pix_fmt nv12 -s:v 1920x1080 -i 1080p_nv12.yuv -vf 'format=nv12,hwupload=extra_hw_frames=16,hwdownload,format=nv12' -an -y out_nv12.yuv It can fix #7418 Signed-off-by: Zhong Li <zhong.li@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RGB32(AV_PIX_FMT_BGRA on intel platforms) format may be used as overlay with alpha blending. So add AV_PIX_FMT_BGRA format support. One example of alpha blending overlay: ffmpeg -hwaccel qsv -c:v h264_qsv -i BA1_Sony_D.jsv -filter_complex 'movie=lena-rgba.png,hwupload=extra_hw_frames=16[a];[0:v][a]overlay_qsv=x=10:y=10' -c:v h264_qsv -y out.mp4 Rename RGB32 to be BGRA to make it clearer as Mark Thompson's suggestion. V2: Add P010 format support else will introduce HEVC 10bit encoding regression. Thanks for LinJie's discovery.
