golang 使用ffmpeg获取rtsp流截图,并生成缩略图

go 程序取流截图

// 根据URL调用ffmpeg 获取截图
func GetIpcScreenShot(ffmpegPath string, url string, screenShotPath string) string {
	var params []string
	params = append(params, "-rtsp_transport")
	params = append(params, "tcp")
	params = append(params, "-timeout")
	// 10s
	params = append(params, "10000000")
	params = append(params, "-y")
	params = append(params, "-i")
	params = append(params, url)
	params = append(params, "-ss")
	params = append(params, "00:00:02")
	params = append(params, "-vframes")
	params = append(params, "1")
	params = append(params, "-f")
	params = append(params, "image2")
	params = append(params, "-vcodec")
	params = append(params, "png")
	params = append(params, screenShotPath)

	resp, err := CallCommandRun(ffmpegPath, params)
	if err != nil {
		fmt.Println(err.Error())
		fmt.Println("获取截图出错，url为--->", url)
	}
	return resp
}
