Andreas Rheinhardt ef6c52f3c5 avcodec/svq3: Avoid overhead of AVBuffer API 
Up until now, the SVQ3 decoder allocated several refcounted buffers,
despite no sharing/refcounting happening at all: Their refcount never
exceeds one and they are treated like ordinary buffers (with the
exception that the pointer used to access them is in the middle of the
allocated buffer, but this does not warrant using the AVBuffer API at
all). Given that using the AVBuffer API incurs overhead, it is no longer
used at all.

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.

Documentation

The offline documentation is available in the doc/ directory.

The online documentation is available in the main website and in the wiki.

Examples
