Jan Ekström c820c2d4bf avformat/mpegts: only reset timestamps to NOPTS for DVB teletext 
While having the possibility of non-NOPTS values that can suddenly
jump in time due to adjustments to match PCR is not nice for DVB
subtitles, apparently the parser for this format bases its behavior on
whether the packets' timestamps are NOPTS or not. Thus while we can
adjust timestamps, we should exclude DVB subtitles from the timestamp
unsetting logic.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • 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.
