Andreas Rheinhardt 27c4e7d99c avformat/smoothstreaming: Fix memleaks on errors 
If an AVFormatContext could be allocated, but white-/blacklists couldn't
be copied, the AVFormatContext would leak as it was only accessible
through a local variable that goes out of scope when one goes to fail.

Furthermore, in case writing a header of a submuxer failed, the options
used for said call could leak.

Both of these memleaks have been fixed.

  • 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.
