Martin Storsjö 15537c904e flvdec: Check the avio_seek return value after reading a metadata packet 
merge from libav: 585dc1aece

If the metadata packet is corrupted, flv_read_metabody can accidentally
read past the start of the next packet. If the start of the  next packet
had been flushed out of the IO buffer, we would be unable to seek to
the right position (on a nonseekable stream).

Prefer to clearly error out instead of silently  trying to read from a
desynced stream which will only be interpreted as garbage.

  • 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.
  • ffserver is a multimedia streaming server for live broadcasts.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
