Andreas Rheinhardt 502c5fe101 avcodec/utils: Remove always-true check 
The first thing avcodec_open2() allocates is the AVCodecInternal. If
allocating it fails, a jump to end occurs; but if an error happens after
its allocation, a jump to free_and_end happens which frees all
allocations performed so far and then jumps to end. Yet free_and_end
contained a check for AVCodecInternal (after having already dereferenced
it to check whether ff_thread_free() needs to be called) which is of
course always true. So remove it.

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.
