• 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 :
