Golang binding for FFmpeg and libav.

Things to know

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.

Getting Started

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
