• I use the bramp/ffmpeg-cli-wrapper of java. How to terminate the execution in the thread ?

  8 mars, par Hao Tan

  I want to use ffmpeg to achieve streaming function

  


  First I created a thread pool

  


   private final Map taskThreads = new ConcurrentHashMap<>();
Thread taskThread = new Thread(() -> {
            try {
                private void startTask(Device task) {
        Thread taskThread = new Thread(() -> {

            FFmpegBuilder builder = new FFmpegBuilder()
                    .setInput(source) 
                    .overrideOutputFiles(true)
                    .addOutput(destination) 
                    .setFormat("flv")
                    .addExtraArgs("-c", "copy") 
                    .done();

            FFmpegExecutor executor = new FFmpegExecutor(ffmpeg, ffprobe);
            executor.createJob(builder).run();
        });
        taskThreads.put(task.getId(), taskThread);
        taskThread.start();
    }


  


  stop code

  


  public void stopTask(Integer taskId) {
        Thread taskThread = taskThreads.get(taskId);
        if (taskThread != null) {
            taskThread.interrupt(); 
            taskThreads.remove(taskId);
            
            DeviceDto task = deviceService.findById(taskId);
            if (task != null) {
                task.setIsOnline(0);
                Device device = new Device();
                BeanUtils.copyProperties(task,device);
                deviceService.update(device);
            }
        }
    }


  


  I call stopTask and cannot terminate the ffmpeg thread

  


  It should be executor.createJob(builder).run(); blocked

  


  How to solve

  


• CSeq errors when RTSP streaming with ffmpeg and ffserver

  11 janvier 2020, par Eroji

  I am trying to live stream a webcam with RTSP h264 feed. I am using ffmpeg and ffserver. The ffserver.conf is as below.

  HTTPPort 8090
  
  HTTPBindAddress 0.0.0.0
  
  MaxHTTPConnections 2000
  
  MaxClients 1000
  
  MaxBandwidth 10000
  
  
  
  <feed>
  
  File /tmp/feed.ffm
  
  FileMaxSize 50M
  
  </feed>
  
  
  
  <stream>
  
  Feed feed.ffm
  
  Format mpjpeg
  
  VideoFrameRate 15
  
  VideoSize 1920x1080
  
  VideoQMin 1
  
  VideoQMax 15
  
  VideoIntraOnly
  
  NoAudio
  
  Strict -1
  
  NoDefaults
  
  </stream>
  
  
  
  <stream>
  
  Feed feed.ffm
  
  Format jpeg
  
  VideoFrameRate 2
  
  VideoSize 1920x1080
  
  VideoQMin 1
  
  VideoQMax 15
  
  VideoIntraOnly
  
  NoAudio
  
  Strict -1
  
  NoDefaults
  
  </stream>

  I have played with the ffmpeg options quite a bit and got it relatively stable, however, the ffmpeg process would still die after some random amount of time with an error like this.

  [rtsp @ 0x7ffbe78c3460] CSeq 11 expected, 0 received.

  My ffmpeg command looks like this

  /usr/bin/ffmpeg -hide_banner -loglevel info -rtsp_transport tcp -nostats -use_wallclock_as_timestamps 1 -i rtsp://user:pass@mycamera/live -async 1 -vsync 1 http://127.0.0.1:8090/feed.ffm

  Can any ffmpeg experts out there help somehow getting this stream to stay stable ?

• Piwik analytics database : migrating from MySQL to MariaDB

  11 novembre 2015, par Piwik Core Team — Meta

  This short blog post is an announcement regarding the Piwik technology stack.

  Piwik compatible with MySQL and MariaDB

  Since our first public release Piwik uses the open source database server MySQL to store the analytics data.

  Piwik is also compatible with MariaDB. MariaDB is an enhanced, drop-in replacement for MySQL.

  Upgrading to MariaDB

  Many users from our community as well as Piwik PRO have confirmed that using MariaDB for Piwik has several advantages. MariaDB has in some cases significantly improved query performance and reliability of Piwik. Because MariaDB 5.5 is a complete drop-in-replacement for MySQL 5.5, upgrading can be as easy as running apt-get install mariadb-server (or equivalent for your platform). Existing third party techologies such as TokuDB (FAQ) and Galera are fully compatible with MariaDB.

  In the future, Piwik will stay compatible with both MySQL and MariaDB.
