# DEPRECATED

根本没有必要开发这个库。不如直接在Go项目里写C模块。对于不会C和不熟悉手动内存管理的Go开发者，不如直接调用命令。

# go-libav

Golang binding for [FFmpeg and libav](https://ffmpeg.org/).

## 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 `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.

```env

# 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"

```

## Examples

Check [advance/example](./advance/example) directory.

Try examples With Docker

```bash

# Run container with Debian 13 (trixie).

sudo docker run --rm -it debian:trixie

# Install development environment.

apt install golang git

# Clone project.

git clone https://github.com/Lensual/go-libav

# Install FFmpeg development libraries.

apt install libavcodec-dev libavdevice-dev libavfilter-dev libavformat-dev libavutil-dev libswresample-dev libswscale-dev

# Build example like 'mux' and then run iut.

cd go-libav/example/mux

go build .

./mux ./test.mp4

```
