Andreas Rheinhardt 15072d2753 avcodec/mlpenc: Simplify finding best codebook Finding the best codebook involves comparing different paths, where each path is a sequence of several decisions (namely which codebook to use). Up until now, these sequence was encoded in a NUL-terminated string and the actual decisions were encoded as ’\0'..'\3' (which encoded 0..3). This commit modifies this to actually encode it via 0..3 by switching away from a C-string to a simple array with an explicit length field.

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.
