Jeremy Dorfman via ffmpeg-devel bb5efd1727 avformat/av1: Initialize padding in ff_isom_write_av1c 
Otherwise, AV1 encodes with FFmpeg trigger use-of-uninitialized-value
warnings under MemorySanitizer, and the output buffer potentially
changes from run to run.

  • 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
