设想一

  //开始录制_option.mp4_save_path = custom_path;_option.mp4_max_second = max_second;vector<Track::Ptr> mytracks = getTracks();auto src = MediaSource::find( DEFAULT_VHOST, "1", "adminstream");/*   if (src) {vector<Track::Ptr> one =src->getTracks();mytracks.emplace_back(one[0]);}*/_mp4 = makeRecorder(sender, getTracks(), type, _option);

设想二

gbcomZlm->mp4test1分支

方案三

 关键技术 

public static void main(String[] args) {String ffmpegExePath = "C:\\workspace\\project\\greejoy\\picManager\\web\\tools\\ffmpeg\\bin\\ffmpeg.exe";String inputFilePath = "C:\\Users\\Dulk\\Desktop\\ukulele\\01\\《小星星》.mp4";String outputFilePath = "C:\\Users\\Dulk\\Desktop\\ukulele\\01\\littleStarJava.jpg";List<String> command = new ArrayList<String>();command.add(ffmpegExePath);command.add("-i");command.add(inputFilePath);command.add("-f");command.add("image2");command.add("-ss");command.add("10");command.add("-t");command.add("0.001");command.add("-s");command.add("320*240");command.add(outputFilePath);ProcessBuilder builder = new ProcessBuilder();builder.command(command);//正常信息和错误信息合并输出builder.redirectErrorStream(true);try {//开始执行命令Process process = builder.start();//如果你想获取到执行完后的信息，那么下面的代码也是需要的StringBuffer sbf = new StringBuffer();String line = null;BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));while ((line = br.readLine()) != null) {sbf.append(line);sbf.append(" ");}String resultInfo = sbf.toString();System.out.println(resultInfo);} catch (IOException e) {e.printStackTrace();}}

 测试语句

   

ffmpeg -i D:/web-video-platform/zlm/www/record/2fbe2a926db241b483ab4ea79950fb0c/dxw3Stream/2024-04-01/142727-142741.mp4  -i D:\web-video-platform\zlm\www\record\1\adminstream\2024-04-01\142727-142743.mp4 
-filter_complex "[1:a]volume=0.3[a1];[0:a][a1]amix=inputs=2:duration=first[a]" -map 0:v -map "[a]" -c:v copy -c:a aac -y d:\output.mp4f

测试脚本

/home/dualven/zlmtest  10.60.2.175

举例：

curl "http://10.60.100.196:6080/index/api/startRecord?secret=tzaaghfRyvwtQ7STrA1ag8K1xtThSk9v&type=1&vhost=__defaultVhost__&app=1&stream=adminstream"

curl "http://10.60.100.196:6080/index/api/stopRecord?secret=tzaaghfRyvwtQ7STrA1ag8K1xtThSk9v&type=1&vhost=__defaultVhost__&app=1&stream=adminstream"
