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.

: 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 ?
