Marvin Scholz 4fa2696a08 configure: fix symbol prefix detection 
The symbol prefix check would incorrectly detect a bogus prefix in
circumstances where sanitizers instrument the build, like when
configuring with the clang-asan toolchain where it would detect the
prefix as __odr_asan_gen_, which is obviously wrong.

To fix this, adjust the prefix detection to only detect a
one-character prefix, which is the only case that matters
anywhere right now.

Librempeg README

Librempeg 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
