• FFmpeg - record from stream terminating unexpectedly using kokorin/Jaffree ffmpeg wrapper for Java

  18 avril 2024, par pyrmon

  I am programming a Spring Boot Application using Maven and Java 21. I am trying to record a stream from a url and save it to a mkv file. I intend to do this with kokorin/Jaffree in version 2023.09.10. The recording seems to work ok, however longer videos are terminating unexpectedly. Sometimes after 5 minutes, other times an hour or even longer. Sometimes with Exit Code 0 and sometimes with 1.

  


  I have implemented the recording like this :

  


  @Override
    public void startRecording(RecordingSchedule recordingSchedule) {
        logger.info("Starting recording for schedule with filename {}", recordingSchedule.getFileName());

        String m3uUrl = recordingSchedule.getM3uUrl();
        LocalDateTime endTime = timeUtils.parseStringToLocalDateTime(recordingSchedule.getEndTime());
        LocalDateTime stopTime = endTime.plusSeconds(20);
        String timeToRecord = timeUtils.calculateTimeToRecord(stopTime);
        Path outputPath = Paths.get("/recordings/" + recordingSchedule.getFileName());

        try {
            FFmpeg.atPath()
                  .addInput(UrlInput.fromUrl(m3uUrl))
                  .addArgument("-xerror")
                  .addArguments("-reconnect", "5")
                  .addArguments("-reconnect_streamed", "5")
                  .addArguments("-reconnect_delay_max", "20")
                  .addArguments("-t", timeToRecord)
                  .addArguments("-c", "copy")
                  .addOutput(
                      UrlOutput.toPath(outputPath))
                  .setLogLevel(LogLevel.WARNING)
                  .execute();
            logger.info("Recording complete. Output file: {}", outputPath.toAbsolutePath());
        } catch (Exception e) {
            logger.error("Error recording M3U stream {}: {}", recordingSchedule.getFileName(), e.getMessage());
        }
    }


  


  And I am calling the method like this :
executorConfig.executorService().submit(() -> ffmpegService.startRecording(recording));

  


  Any ideas what I am doing wrong ?
Here are the log lines at the beginning and end of recording of the past two attempts :

  They were supposed to run nearly 3 hours and the other one over 3 hours. And with the timestamps you can see that they are not running nearly as long.
Thank you for your help !

  


• Ffmpeg RTSP stream with size=N/A bitrate=N/A [closed]

  6 octobre 2024, par Comycos

  When I try to stream a video it seems to work but bitrate and size are N/A frame=  277 fps= 26 q=-1.0 size=N/A time=00:00:11.07 bitrate=N/A speed=1.05x

  


  I run the following command to stream a video to a RTSP server :
ffmpeg -re -stream_loop -1 -i idurre-2024-09-17-12h33m19s.mp4 -c copy -f rtsp -rtsp_transport tcp rtsp://localhost:8554/test

  


  The output ffmpeg is like this :

• Understand your visitors by seeing where they click, hover, type and scroll, and replay their actions in a video

  18 mai 2017, par InnoCraft — Plugins

  Hi, this is Mike from InnoCraft, the company of the makers of Piwik Analytics which is used by over 1 million websites and apps in over 150 countries.

  I’m very proud to introduce you to our Heatmap & Session Recording feature which lets you analyze your visitors’ behaviour on a whole new level that was not possible before.

  With Heatmaps you can see where people think something is clickable but it is not, how far down the page do they scroll, whether they see your important buttons and Call To Actions, or even whether you can re-position your page layout to put the important content in more visible places. Both the mouse movements and all clicks are recorded and viewable on these new beautiful heatmap visualisations.

  With Session Recordings, you get to see a video showing exactly what a visitor did on your pages, including all mouse movements, scrolls, text typed in the keyboard, and more. Using these recordings you can improve the usability on your website, replace costly (and less effective) eye tracking sessions, and you can now see exactly what problems your visitors experience or how they behave on your website. This gives new insights and ability to understand what your users think.

  -> Read the rest of the story on the Heatmaps & Session Recordings Marketplace page.

  What does the new Heatmaps reports look like ?

  Here is below just a little preview of the new Heatmaps reports.

  1) Mouse move and Click Heatmaps

  

  2) A Scroll Heatmap

  

  What does the new Session Recording look like ?

  You can replay videos of exactly what your users did on your websites including mouse moves, scrolls, typing in forms, and more.

  1) Listing all recorded video sessions

  

  2) Playing a recorded video session
