Golang binding for FFmpeg and libav.

1. This package is implemented using CGO and requires FFmpeg's header files and libraries for compilation.
2. Due to well-known performance issues with CGO calls, it is recommended to use C/CPP to achieve your needs.

Package go-libav/av* are cgo bindings. Before using this package, you'd better to master the basic usage of the FFmpeg library.

Package golibav/advance is a secondary package to simplify use in go.

Need Golang version 1.21 and FFmpeg library version 6.1.

Set your environment variable if your library is not in the default directory.

# using pkg-config
PKG_CONFIG_PATH="/ffmpeg/lib/pkgconfig"

# or set compiler flags
CGO_LDFLAGS="-L/ffmpeg/lib -lavcodec -lavdevice -lavfilter -lavformat -lavutil -lswresample -lswscale"
CGO_CFLAGS="-I/ffmpeg/include"

Check advance/example directory.
