先按照ffmpeg的安装攻略,搞定你CentOS上的ffmpeg,我目前使用的版本是3.0.2
然后直接上代码
package main
import (
"fmt"
"log"
"os"
"os/exec"
"time"
)
func main() {
var srcFileName, outputfilename string
log.SetFlags(log.Lshortfile | log.Ldate | log.Ltime)
if len(os.Args) != 3 {
fmt.Println("简单的转码服务,利用FFMPEG和编码器转换成MP4.")
fmt.Println("使用:[输入文件路径] [输出文件路径]")
os.Exit(1)
} else {
srcFileName = os.Args[1]
outputfilename = os.Args[2]
}
param := "ffmpeg -y -i " + srcFileName + " -metadata:s:v rotate=0 -vf fps=15,setdar=dar=1 -s 480x480 -pix_fmt yuv420p -strict -2 -c:v h264 -b:v 500k -b:a 48k -ss 0 -t 300 -threads 2 " + outputfilename + ""
fmt.Println("parm : ", param)
start := time.Now()
_, err := exec.Command("bash", "-c", param).CombinedOutput()
if err != nil {
fmt.Println("error: " + err.Error())
} else {
fmt.Println(" out file : ", outputfilename, " exec time ", time.Now().Sub(start).Seconds())
}
}
执行下:
go run main.go simple.mov simple_1.mp4
