Zhao Zhili c2c96c4c24 avfilter: add scale_vt for videotoolbox pix_fmt 
For example,

./ffmpeg -hwaccel videotoolbox \
	-hwaccel_output_format videotoolbox_vld \
	-i ios-265.mov \
	-c:v hevc_videotoolbox \
	-profile:v main \
	-b:v 3M \
	-vf scale_vt=w=iw/2:h=ih/2:color_matrix=bt709:color_primaries=bt709:color_transfer=bt709 \
	-c:a copy \
	-tag:v hvc1 \
	/tmp/test.mp4

Input: hevc (Main 10) (hvc1 / 0x31637668), yuv420p10le(tv, bt2020nc/bt2020/arib-std-b67), 3840x2160
Output: hevc (Main) (hvc1 / 0x31637668), yuv420p(tv, bt709, progressive), 1920x1080

  • 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.
