How to use Jaffree with Spring Boot for streaming a RTSP flow
25 août 2022, par JmarchiIm trying to build a APIRest and one of the things i want to do is recirculate the rtsp video provided by some security cameras to the frontend.


I have found the Jaffree, a dependency that integrates the ffmpeg into spring, until then all is good.


The problem is when i try to send the video to the frontend (make in React) i recieve this error :




Starting process : ffmpeg


Waiting for process to finish


...


Input #0, mpjpeg, from __________


Duration : N/A, bitrate : N/A


Stream #0:0 : Video : mjpeg (Baseline), yuvj420p(pc, bt470bg/unknown/unknown), 1920x1080 [SAR 1:1 DAR 16:9], 25 tbr, 25 tbn


[warning] Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (tcp ://127.0.0.1:52225) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.


Output #0, ismv, to 'tcp ://127.0.0.1:52225' :

: Interrupting starter thread (task-1) because of exception : TCP negotiation failed




The code in the backend is this :


@GetMapping(value = "/{id}/video")
public ResponseEntity<streamingresponsebody> getVideo() {
 String url = "**********";

 return ResponseEntity.ok()
 .contentType(MediaType.APPLICATION_OCTET_STREAM)
 .body(os ->{
 FFmpeg.atPath()
 .addArgument("-re")
 .addArguments("-acodec", "pcm_s16le")
 // .addArguments("-rtsp_transport", "tcp")
 .addArguments("-i", url)
 .addArguments("-vcodec", "copy")
 .addArguments("-af", "asetrate=22050")
 .addArguments("-acodec", "aac")
 .addArguments("-b:a", "96k" )
 .addOutput(PipeOutput.pumpTo(os)
 .disableStream(StreamType.AUDIO)
 .disableStream(StreamType.SUBTITLE)
 .disableStream(StreamType.DATA)
 .setFrameCount(StreamType.VIDEO, 100L)
 //1 frame every 10 seconds
 .setFrameRate(0.1)
 .setDuration(1, TimeUnit.HOURS)
 .setFormat("ismv"))
 .addArgument("-nostdin")
 .execute();
 });
 }
</streamingresponsebody>

And this is the html part :


<video width="100%" height="auto" controls="controls" autoplay="autoplay" muted="muted" src="http://localhost:7500/***/1/video">
 Sorry, your browser doesn't support embedded videos.
 </video>


What is it missing for the TCP negotiation ?

Joining/Concatenating more than one video files in Java Spring Boot
7 décembre 2020, par Rohan ShahI am trying to join/concate multiple files in Java, so far the procedure that I was following (
https://github.com/bramp/ffmpeg-cli-wrapper) was going alright, but in this procedure, there were a couple of lines that I could not understand.

Code I am following :


FFmpeg ffmpeg = new FFmpeg("/path/to/ffmpeg");
FFprobe ffprobe = new FFprobe("/path/to/ffprobe");

FFmpegBuilder builder = new FFmpegBuilder()

 .setInput("input.mp4") // Filename, or a FFmpegProbeResult
 .addInput("input2.mp4") // <-------------------------------- Second file that I added
 .overrideOutputFiles(true) // Override the output if it exists

 .addOutput("output.mp4") // Filename for the destination
 .setFormat("mp4") // Format is inferred from filename, or can be set
 .setTargetSize(250_000) // Aim for a 250KB file

 .disableSubtitle() // No subtiles

 .setAudioChannels(1) // Mono audio
 .setAudioCodec("aac") // using the aac codec
 .setAudioSampleRate(48_000) // at 48KHz
 .setAudioBitRate(32768) // at 32 kbit/s

 .setVideoCodec("libx264") // Video using x264
 .setVideoFrameRate(24, 1) // at 24 frames per second
 .setVideoResolution(640, 480) // at 640x480 resolution

 .setStrict(FFmpegBuilder.Strict.EXPERIMENTAL) // Allow FFmpeg to use experimental specs
 .done();

FFmpegExecutor executor = new FFmpegExecutor(ffmpeg, ffprobe);

// Run a one-pass encode
executor.createJob(builder).run();

// Or run a two-pass encode (which is better quality at the cost of being slower)
executor.createTwoPassJob(builder).run();


These are the lines throwing error :


FFmpeg ffmpeg = new FFmpeg("/path/to/ffmpeg");
FFprobe ffprobe = new FFprobe("/path/to/ffprobe");


In these lines, I am providing a path like this,


FFmpeg ffmpeg = new FFmpeg("D:/");
FFprobe ffprobe = new FFprobe("D:/");


which leads to an error


java.io.IOException: CreateProcess error=5


I believe the
ffmpegin/path/to/ffmpegandffprobein/path/to/ffprobeare files, not directories, which is why it threw an execution permission error, but as I looked into the repository (link given above) I was not able to find this particular file in the given link.

There were a couple of Java files named
ffmpeg.javaandffprobe.java, but when I tried using them in the code then I got the same error, so I want to know which files am I supposed to have in these paths

How to split the Video into Frames using FFMPEG in Spring-Boot ?
8 octobre 2020, par Abhinay KTo fetch Frames from Video with 5fps rate with specified Start and end Time in video with following FFMPEG command,


ffmpeg -i input.mp4 -ss 00:00:54 -to 00:01:53 -r 5 -f image2 image-%13d.png,


I want to implement the same in the Spring-boot application,


I found the following code snippet to fetch frames from Video,


public static void main(String[] args) {
 Java2DFrameConverter bimConverter = new Java2DFrameConverter();
 FFmpegFrameGrabber g = new FFmpegFrameGrabber("input.mp4");
 try {
 g.start();
 for (int i = 0; i < 50; i++) {
 ImageIO.write(bimConverter.convert(g.grab()), "png", new File(
 "image-" + System.currentTimeMillis() + ".png"));
 }
 g.stop();
 } catch (IOException ie) {
 ie.printStackTrace();
 } catch (Exception e) {
 e.printStackTrace();
 }
}


but I required logic to implement as output from following command,


ffmpeg -i input.mp4 -ss 00:00:54 -to 00:01:53 -r 5 -f image2 image-%13d.png,


Please help me out the logic need to implement,
