Andreas Rheinhardt d496bbe105 avcodec/v210enc: Move ff_v210enc_init into a header This removes a dependency of checkasm on lavc/v210_enc.o and also allows to inline ff_v210enc_init() irrespectively of interposing. This dependency pulled basically all of libavcodec into checkasm, in particular all codecs. This also makes checkasm work when using shared Windows builds: On Windows, it needs to be known to the compiler whether a data symbol is external to the library/executable or not; hence the need for av_export_avutil. checkasm needs access to the internals of the libraries it tests and is therefore linked statically to all the libraries. This means that the users of avpriv_cga_font and avpriv_vga16_font in libavcodec (namely ansi.o, bintext.o, tmv.o) end up in the same executable as the symbols, although they have been compiled as if these symbols were external, leading to linker errors. With this commit said files are discarded by the linker, bypassing this problem. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>		3 years ago

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

The offline documentation is available in the doc/ directory.

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

Examples

Coding examples are available in the doc/examples directory.
