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 Streaming Video SpringBoot endpoint not show video duration in video players
7 avril 2024, par lxluxo23it turns out that I've been working on a personal project just out of curiosity.
the main function is to stream video by first encoding it through ffmpeg
then playback said video from any other device
call it "plex" very very primitive


although I achieve my goal which is to encode and send the video to the devices that make the request
this video is sent so to speak as a live broadcast.
I can only pause it, no forward or rewind, anyone have any idea what I am doing wrong or if I should take some other approach either in my service or controller ?


I leave fragments of my code


THE CONTROLLER


@RestController
@RequestMapping("/api")
@Log4j2
public class StreamController {

 @Autowired
 VideoStreamingService videoStreamingService;

 @Autowired
 VideoService videoService;


 @GetMapping("/stream/{videoId}")
 public ResponseEntity<streamingresponsebody> livestream(@PathVariable Long videoId,@RequestParam(required = false) String codec) {
 Video video = videoService.findVideoById(videoId);
 if (video != null) {
 Codec codecEnum = Codec.fromString(codec);
 return ResponseEntity.ok()
 .contentType(MediaType.valueOf("video/mp4"))
 .body(outputStream -> videoStreamingService.streamVideo(video.getPath(), outputStream,codecEnum));
 }
 return ResponseEntity.notFound().build();
 }
}
</streamingresponsebody>

THE SERVICE


@Service
public class VideoStreamingService {

 public void streamVideo(String videoPath, OutputStream outputStream, Codec codec) {

 FFmpeg ffmpeg = FFmpeg.atPath()
 .addArguments("-i", videoPath)
 .addArguments("-b:v", "5000k")
 .addArguments("-maxrate", "5000k")
 .addArguments("-bufsize", "10000k")
 .addArguments("-c:a", "aac")
 .addArguments("-b:a", "320k")
 .addArguments("-movflags", "frag_keyframe+empty_moov+faststart")
 .addOutput(PipeOutput.pumpTo(outputStream)
 .setFormat("mp4"))
 .addArgument("-nostdin");
 if (codec == Codec.AMD) {
 ffmpeg.addArguments("-profile:v", "high");
 }
 ffmpeg.addArguments("-c:v", codec.getFfmpegArgument());
 ffmpeg.execute();
 }
}


I have some enums to vary the encoding and use hardware acceleration or not.


and here is an example from my player
the endpoint is the following


http://localhost:8080/api/stream/2?codec=AMD
screenshot

I'm not sure if there's someone with more knowledge in either FFmpeg or Spring who could help me with this minor issue, I would greatly appreciate it. I've included the URL of the repository in case anyone would like to review it when answering my question




I tried changing the encoding format.
I tried copying the metadata from the original video.
I tried sending a custom header.
None of this has worked.


I would like to achieve what is mentioned in many sites, which is when you load a video from the network, the player shows how much of that video you have in the local "buffer".

Frames from Video Using OpenCV in Ubuntu with Java 17
2 août 2023, par bstrdnI've been trying to extract frames from a video using OpenCV in an Ubuntu environment with Java 17, but all my attempts have been unsuccessful so far. The main issue is that ffmpeg is not detected by the OpenCV library on ubuntu.


Here's my test code :


Main class


import org.opencv.core.Core;
import org.opencv.videoio.VideoCapture;

public class Main {
 public static String videoPath = "";
 static {
 String osName = System.getProperty("os.name").toLowerCase();
 if (osName.contains("win")) {
 System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
 videoPath = ClassLoader.getSystemResource("video.mp4").getPath();
 } else {
 videoPath = "/video.mp4";
// System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
 System.load("/usr/lib/opencv_java470.so");
 }
 }

 public static void main(String[] args) throws InterruptedException {
 VideoCapture videoCapture = new VideoCapture(videoPath);
 if (!videoCapture.isOpened()) {
 System.out.println("Error opening video file.");
 } else {
 System.out.println("Everything is fine.");
 }
 System.out.println(Core.getBuildInformation());
 Thread.sleep(1000000000000000000L);
 }
}

How can i fix this ? I'm deathly tired(


Thank you in advance for your assistance !


First I tried installation following the official instructions.https://github.com/bytedeco/javacv#required-software


Then the solution provided in https://stackoverflow.com/a/76750478/8087508,


but the result is the same.
