Andreas Rheinhardt 6e0dd41fa3 avformat/mlvdec: Check for existence of AVIOContext before using it
The mlv demuxer supports input split into multiple files; if invalid
data is encountered when parsing one of the subsequent files, that file
is closed. But at this point some index entries belonging to this file
might already have been added. In this case, the read_packet function
might try to use the AVIOContext (which is NULL) to read data which will
of course crash. This commit fixes this.

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.
