• ffmpeg timeout with rtsp

  17 janvier 2024, par eSlavko

  I have script that capture image from wifi camera with ffmpeg.
It works fine until camera is not reachable due to network troubles.
The script stuck in ffmpeg capture and never exit. Is it possible to have some kind of timeout ? -stimeout (in miliseconds) seems not working.

  


  There is part of script that capture images. (there are some manipulation after that)

  


  #!/bin/bash
week="$(date '+%Y_%U')"
ts="$(date '+%Y-%m-%d_%H:%M:%S')"
ffmpeg -rtsp_transport tcp -y -i "rtsp://192.168.64.101" -frames:v 1 $week/$ts.jpg -stimeout 3000 -y


  


  I did test on other camera and results are :

  


  ffmpeg -y -i "rtsp://192.168.64.112:8554/profile0" -frames:v 1 Ilatest.jpg


  


  Does work OK, but with timeout of 5 seconds as

  


  ffmpeg -timeout 5000000 -y -i "rtsp://192.168.64.112:8554/profile0" -frames:v 1 Ilatest.jpg


  


  doesn't and I got error report as :

• avformat/matroskaenc : Use common function for H.2645 annex B->mp4

  16 janvier 2022, par Andreas Rheinhardt

  avformat/matroskaenc : Use common function for H.2645 annex B->mp4
  Matroska does not have different profiles that allow or disallow
  
  in-band extradata, so one can just use the ordinary H.264 function
  
  for H.265, too. (Both use ff_avc_parse_nal_units() internally anyway.)

• How to use ffmpeg to convert video into the audio format with nodejs and angular in web app

  31 août 2021, par Amir Shahzad

  I want to convert the video into the audio format using ffmpeg in nodejs but I not know how I can implement it in the angular app with nodejs.

  


  This is my nodejs code

  


    const express = require('express');
  const ffmpeg  = require('fluent-ffmpeg');
  const fileUpload = require('express-fileupload');
  const cors   = require('cors')
  const app = express();

  app.use(fileUpload({
     useTempFiles: true,
     tempFileDir: 'temp/'
  }));
  app.use(express.json());
  app.use(express.urlencoded({ extended: true }));
  app.use(cors({ origin: 'http://localhost:4200' }));

  ffmpeg.setFfmpegPath('/usr/bin/ffmpeg');

  // Converting mp4 to audio
  app.post('/mp4tomp3', (req, res) => {
     res.contentType('video/avi');
     res.attachment('output.mp3');
     req.files.mp4.mv("temp/" + req.files.mp4.name , function(err) {
      if(err){
        res.sendStatus(500).send(err)
    }else{
        console.log("Fiel Uploaded Successfully.!");
    }
   });
     ffmpeg('temp/' + req.files.mp4.name)
       .toFormat('mp3')
       .on('end', function() {
            console.log('Done');
    })
   .on('error', function(err){
         console.log('An Error Occured' + err.message)
    })
    .pipe(res, {end: true})
  })

  app.listen(3000, () => {
    console.log('Server Start On Port 3000')
  })


  


  This code is working good when I use index.html file in the nodejs app but its give an error while I remove index.html file and use angular app for frontend then it give error in nodejs mp4 not defined and name mv is not defined Please tell me how I can implement it using angular framework

  


  This is my app.component.html file

  


     <div class="container">&#xA;     <h1>Video Proccessing App</h1>&#xA;     <form>&#xA;        <input type="file" formcontrolname="mp4" />&#xA;         <input type="submit" value="Convert" />&#xA;     </form>&#xA;  </div>&#xA;  &#xA;

  


  This is my app.component.ts file

  


       import { Component, OnInit } from '@angular/core';
     import { FormBuilder, FormGroup, Validators } from '@angular/forms';
     import { VideoConversionService } from 'src/services/video-conversion.service';

     @Component({
        selector: 'app-root',
        templateUrl: './app.component.html',
        styleUrls: ['./app.component.css']
     })
     export class AppComponent implements OnInit {

         submitted =false;
         form! : FormGroup
         data:any


        constructor(private formBuilder: FormBuilder,
        private videoService: VideoConversionService){}


       creatForm(){
          this.form = this.formBuilder.group({
          mp4: ['', Validators.required],
       });
      }
      ngOnInit(): void {
         this.creatForm();

      }


      convertVideo(){
          this.submitted = true
          this.videoService.conversion(this.form.value).subscribe(res => {
          this.data = res;
         // console.log(this.data)
         //console.log(this.form.value)
     })
     }

     }


  


  This is my service file for handling the backend api in my angular app

  


  import { Injectable } from '@angular/core';
import { HttpClient  } from '@angular/common/http';
@Injectable({
  providedIn: 'root'
})
export class VideoConversionService {

constructor(private httpClient: HttpClient) { }

conversion(data: any){
   return this.httpClient.post('http://localhost:3000/mp4tomp3', data)
}
}


  


  This is Screenshot of chrome error

  


  

  


  This is the screenshot of the nodejs app error while I click on the convert button
