Andreas Rheinhardt 244db71037 avcodec/libx265: Don't use AVBPrint unnecessarily 
This code uses the AVBPrint API for exactly one av_bprintf()
in a scenario in which a good upper bound for the needed
size of the buffer is available (with said upper bound being
much smaller than sizeof(AVBPrint)). So one can simply use
snprintf() instead. This also avoids the (always-false due to
the current size of the internal AVBPrint buffer) check for
whether the AVBPrint is complete.

Furthermore, the old code used AV_BPRINT_SIZE_AUTOMATIC
which implies that the AVBPrint buffer will never be
(re)allocated and yet it used av_bprint_finalize().
This has of course also been removed.

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.
