go-ffmpeg-core
ffmpeg core for golang
基于ffmpeg命令封装简单功能，因此运行环境需事先安装有ffmpeg命令。

1. 剥离视频文件的音频/视频
package main
import (
go_ffmepg_core "github.com/Resynz/go-ffmpeg-core"
"log"
)
func main () {
resourcePath:="./test.mp4" // 原视频路径
outputPath:="./test-peel-audio.m4a" // 文件输出路径
peel:=&go_ffmpeg_core.Peel{
Command: "ffmpeg",
ResourcePath: resourcePath,
OutputPath: outputPath,
Type: go_ffmpeg_core.PeelTypeAudio, // 指定剥离类型为音频/视频
Stream: "", // 如果该视频文件中有存在多条音轨，可指定音轨编号
}
err:=peel.Execute()
if err!=nil{
log.Fatalf("peel failed! error:%s\n",err)
}
log.Println("peel done.")
}
2. 合并音频、视频
package main
import (
go_ffmepg_core "github.com/Resynz/go-ffmpeg-core"
"log"
)
func main () {
merge:=&go_ffmpeg_core.MergeAV{
Command: "ffmpeg",
VideoPath: "./test-v.mp4", // 纯视频文件路径
AudioPath: "./test-a.m4a", // 纯音频文件路径
OutputPath: "./merge.mp4", // 结果输出路径
}
if err:=merge.Execute();err!=nil{
log.Fatalf("merge failed! error:%s\n",err.Error())
}
log.Println("merge done.")
}
3. 转换格式
package main
import (
go_ffmepg_core "github.com/Resynz/go-ffmpeg-core"
"log"
)
func main () {
transform:=&go_ffmpeg_core.Transform{
Command: "ffmpeg",
ResourcePath: "./test.mp4",
OutputPath: "./test.mkv",
}
if err:=transform.Execute();err!=nil{
log.Fatalf("tranform failed! error:%s\n",err.Error())
}
log.Println("transform done.")
}
