Niklas Haas 4ec45aca36 swscale/utils: fix leak on threaded ctx init failure
This count gets incremented after init succeeds, when it should be
incremented after *alloc* succeeds. Otherwise, we leak the context on
failure.

There are no negative consequences of incrementing for
allocated-but-not-initialized contexts, as the only functions that
reference it will, in the worst case, simply behave as if called on
allocated-but-not-initialized contexts, which is in line with expected
behavior when sws_init_context() fails.

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 means to alter decoded audio and video through a directed graph of connected 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.

Documentation
