FFmpeg - record from stream terminating unexpectedly using kokorin/Jaffree ffmpeg wrapper for Java
18 avril 2024, par pyrmonI 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 -ss parameter is the video duration, Output file is empty
16 avril 2024, par noun nilThe main function is to obtain the corresponding video frame based on the input seconds.Before processing, the duration of the video will be obtained to determine whether the input is within the duration range of the video.
