Zhao Zhili f7545e90df avutil/hwcontext_opencl: Add map from Videotoolbox to OpenCL
For example:
./ffmpeg -hwaccel videotoolbox \
	-hwaccel_output_format videotoolbox_vld \
	-i foo.mp4 \
	-vf hwmap=derive_device=opencl,transpose_opencl=dir=clock,hwmap,format=nv12 \
	-c:v hevc_videotoolbox \
	-c:a copy \
	-b:v 2M -tag:v hvc1 bar.mp4

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
