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

  18 avril, 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 dynamic cropping using sendcmd correct syntax ?

  19 avril, par Sulli

  I'm trying to dynamically crop a video using FFmpeg's sendcmd filter based on coordinates specified in a text file, but the crop commands do not seem to be taking effect. Here's the format of the commands I've tried and the corresponding FFmpeg command I'm using.

  


  Following the documentation https://ffmpeg.org/ffmpeg-filters.html#sendcmd_002c-asendcmd, commands in the text file (coordinates.txt) like this :

  


  0.05 [enter] crop w=607:h=1080:x=0:y=0;
0.11 [enter] crop w=607:h=1080:x=0:y=0;
...


  


  Ffmpeg command :

  


  ffmpeg -i '10s.mp4' -filter_complex "[0:v]sendcmd=f=coordinates.txt" -c:v libx264 -c:a copy -r 30 output.mp4


  


  This doesn’t seem to do anything.

  


  And with the commands in the text file (coordinates.txt) like this :

  


  0.05    crop w 607, crop h 1080, crop x 0, crop y 0;
0.11    crop w 607, crop h 1080, crop x 0, crop y 0;
...


  


  Ffmpeg command :

  


  ffmpeg -i '10s.mp4' -filter_complex "[0:v]sendcmd=f=coordinates.txt,crop" -c:v libx264 -c:a copy -r 30 output.mp4


  


  (following this answer https://stackoverflow.com/a/67508233/1967110)

  


  This one does something, but something very messy. It looks like it crops at the correct x, but does not take into account the y, w or h, and it puts the crop at the right side of the input video.

  


  Edit : what I’m trying to do is create a 607x1080 (portrait format, 9:16) video from a 1920x1080 video, with the x parameter varying across time (imagine sliding horizontally a 9:16 frame over a 16:9 video). So fixed w, h and y, just x varying.

  


  I’m using this ffmpeg version :
