Justin Ruggles 97f47fd601 mov: Fix start_time for streams with empty edits in the middle 
Empty edits can occur at any position within the edit list except for at
the end. Empty edits in the middle should not impact the reported stream
start_time or the video PTS adjustment, so only include empty edits at
the start of the list in empty_edits_sum_duration.

  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides a mean to alter decoded Audio and Video through chain of 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.
