Marvin Scholz 86b252ea9d avfilter/vf_tpad: accept hardware frames in clone-only mode 
When no drawing is to be performed, tpad can work fine with
hardware frames, so advertise this in the query_formats
callback and ensure the drawing context is never initialised
when just cloning frames.

  • 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.
