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>

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.
Libraries
libavcodecprovides implementation of a wider range of codecs.libavformatimplements streaming protocols, container formats and basic I/O access.libavutilincludes hashers, decompressors and miscellaneous utility functions.libavfilterprovides means to alter decoded audio and video through a directed graph of connected filters.libavdeviceprovides an abstraction to access capture and playback devices.libswresampleimplements audio mixing and resampling routines.libswscaleimplements 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,ismindexandqt-faststart.
