Error with RTSP Stream in Node.js : Could not find codec parameters for stream 0 (Video : h264, none)
7 août 2023, par theplaceofburakI have a Node.js application that uses the node-rtsp-stream package to stream an RTSP video from an IP camera. However, when I run the application, I encounter the following errors in the console after a few minutes :


[rtsp @ 000002402795dd80] Could not find codec parameters for stream 0 (Video: h264, none): unspecified size
Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options
Input #0, rtsp, from 'rtsp://fake_test:jksdfhskhdfsomethingfake@111.111.11.1111:50213/cam/realmonitor?channel=1&subtype=1'(fake rtsp link used for privacy)':

[out#0/mpegts @ 0000024027987b80] Output file does not contain any stream
Error opening output file -.
Error opening output files: Invalid argument
RTSP stream exited with error


I am certain that the RTSP stream from the camera is in H.264 - MPEG-4 AVC format, and I can play it in VLC without any issues. However, when I try to stream it using the node-rtsp-stream package, I encounter these errors.


Here is my Node.js code :


const express = require('express');
const Stream = require('node-rtsp-stream');

const app = express();
const port = 4000;


const stream = new Stream({
 name: 'rtsp_server_name',
 streamUrl: 'rtsp://fake_test:jksdfhskhdfsomethingfake@111.111.11.1111:50213/cam/realmonitor?channel=1&subtype=1'(fake rtsp link used for privacy),
 wsPort: 9999,
 ffmpegOptions: {
 '-stats': '', // an option with no necessary value uses a blank string
 '-r': 30, // options with required values specify the value after the key
 },
});

// Middleware to log each request
app.use((req, res, next) => {
 console.log(`${req.method} ${req.url}`);
 next();
});

app.get('/', (req, res) => {
 res.send('Hello World');
});

app.listen(port, () => {
 console.log(`Server running at http://localhost:${port}/`);
});

// Event listener to check if the RTSP stream is ready
stream.on('data', (data) => {
 if (data.includes('frame=')) {
 console.log('RTSP stream is ready and streaming.');
 }
});


I have tried increasing the values for 'analyzeduration' and 'probesize' options, but the errors persist. How can I resolve these errors and successfully stream the RTSP video in H.264 format using the node-rtsp-stream package ? Any help or guidance would be appreciated. Thank you !

Error : ffmpeg exited with code 1 :
16 juin 2022, par jibranI am using the videoshow node package to create straightforward video slideshows based on images using
ffmpeg, with additional features such as audio. I am following the documentation exactly but I get the following error :




Error : ffmpeg exited with code 1 :





Here is the code :



var videoshow = require('videoshow')
 const ffmpeg = require('@ffmpeg-installer/ffmpeg');


 var images = [
 'image1.jpg',
 'image1.jpg',
 'image1.jpg'

 ]
 var videoOptions = {

 size: '640x640',
 audioBitrate: '128k',
 audioChannels: 2,

 pixelFormat: 'yuv420p'
 }

 var videoOptions = {
 fps: 24,
 transition: false,
 videoBitrate: 1024 ,
 videoCodec: 'libx264', 
 size: '640x640',
 outputOptions: ['-pix_fmt yuv420p'],
 format: 'mp4' 
 }
 videoshow(images, videoOptions)
 .audio('nd.mp3')
 .save('/home/jibran/Desktop/video.avi')
 .on('start', function (command) {
 console.log('ffmpeg process started:', command)
 })
 .on('error', function (err, stdout, stderr) {
 console.error('Error:', err)
 console.error('ffmpeg stderr:', stderr)
 console.error('ffmpeg stdeout:', stdout)
 })
 .on('end', function (output) {
 console.error('Video created in:', output)
 })

 and on a console I get

Raspberry crosscompilation in Eclipse
27 juin 2018, par gogoerI want to compile an application for Raspberry in Eclipse (in windows). I installed SysGCC, configured Eclipse for crosscompiling. And if I create something like "Hello world" - everything is ok. Eclipse creates binaries which wonderfully works on Raspberry.
But i need use FFMPEG libraries in my application . Here the minimal code of application :#include <libavcodec></libavcodec>avcodec.h>
#include <libavformat></libavformat>avformat.h>
#include <libswscale></libswscale>swscale.h>
int main(void) {
av_register_all();
return EXIT_SUCCESS;
}I added libraries in project config. Project compiles good, but linker gives a lot of errors :
