  • 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 - copy the SPECIFED tracks only, ignore all others

    10 janvier 2024, par GDP

    I have some very strange MP4 files that we get regularly for processing created by Wowza. Neither FFMPEG or MEDIAINFO can detect that there are subtitles soft-coded in them, but they ARE there, I can extract them with ccextractor, and when they're played, the captions appear later in the video where the actually start in the timeline.

    


    I've tried every variation of copying with/without re-encoding, but all the answers show how to "omit" the subtitles with -sn such as these :

    


     ffmpeg -i 3078.mp4 -c copy -sn 3078_sn.mp4
 ffmpeg -i 3078.mp4 -c:v libx264 -c:a ac3 -map 0:v:0 -map 0:a:1 3078_sn.mp4
 ffmpeg -i 3078.mp4 -map 0:v:0 -map 0:a:0  -map -0:s -map -0:d  -c copy 3078_sn2.mp4 -y

Unsupported codec with id 0 for input stream 2


    


    The problem seems to be that FFMPEG isn't detecting they're there, and so copies them anyways. My assumption is that they're not stored in the header of the MP4 properly (or however that's done), so get because they're later detect, but weren't omitted when it checked the header (pure guesswork on that).

    


    So, is there a way to copy ONLY the video, regardless of whatEVER tracks may or not be in the file, then do the same for audio, and then merge the two single-track files ?

    


  • Launching ffmpeg from inside my C code doesn't convert video stream from fifo

    13 mai 2017, par abraxas1

    (Beaglebone Black, ubuntu 16.04 linux 4.4.62-ti-r99)

    I have a raw h264 feed coming into my C program (into a callback from a custom API) and then I named-piped the raw h264 to a file and this CLI command converts that file successfully.

    ffmpeg -report -re -framerate 30 -y -f h264 -i orbi_0148.cam1.h264 -c:v copy -an -video_size 1920x1080 -f mp4 orbi_0148.cam1-1.mp4

    I then try to launch this command from my program with the same options using execv(),

    first mkfifo the fifo’s,

    then launch ffmpeg (shown below) starts the streaming form the cameras to my callback function, and out to the fifos.

    I close the fifos at the end of video recording, and don’t get any file created and get this output, which I don’t understand at all.
    (the successful command line output follows below this output generated from execv())
    thanks, any help much appreciated.
    hardware has come in now and the spot light is on me.

    (execv output with options -report -y -i /tmp/fifocam3.h264 -c:v copy -an -video_size 1920x1080 -f mp4 /media/sd-card/orbi_0140.cam3.mp4)
