Charles Liu aa25198f1b avformat/mov: fix hang while seek on a kind of fragmented mp4 
Binary searching would hang if the fragment items do NOT have timestamp for the
specified stream.

For example, a fmp4 consists of separated 'moof' boxes for each track, and
separated 'sidx' for each segment, but no 'mfra' box.  Then every fragment item
only have the timestamp for one of its tracks.

Example:
ffmpeg -f lavfi -i testsrc -f lavfi -i sine -movflags dash+frag_keyframe+skip_trailer+separate_moof -t 1 out.mp4
ffmpeg -ss 0.5 -i out.mp4 -f null none

Also fixes the hang in ticket #7572, but not the reason for having
AV_NOPTS_VALUE timestamps there.

  • 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.
