• Combining Video and Audio of different length in bulk

  25 mai 2017, par user2981223

  I am going through a tv series right now and editing the files to be to my liking. I have one set which has the video I want and one set that has the audio. I have a batch file that I can run that takes the video from every file in folder "A" and the audio from every file in folder "B" and outputs it to a folder named "output." But with this particular series, that is only half of what I need done.

  At the end of every episode of the files in the "B" folder there are some extra things. What I would like to do is take the audio and video from "A" and the audio from "B", combine it all into one file and also take the "A" and "B" files, compare the time stamps, and add the extra video from "B" to the output file.

  Let me put it another way. Let’s say "A" is 1080p with Japanese audio and is 20 minutes long. Let’s say "B" is 720p with English audio and is 23 minutes long. I want the whole 1080p video with both audio tracks, plus the 720p video spliced onto the end. Both files start at the same spot so syncing isn’t an issue. The issue is that the difference in time is different for every episode. So some episodes are 3 minutes longer, some only 30 seconds. Is there a way to make ffmpeg or another tool look at the difference in times and just add the excess to the output file ?

  Sorry for being long winded. Thanks for any help and guidance.

• getting errors from FFMpeg when spawned from .NET

  18 mars 2014, par Brannon

  When I run FFMpeg from the command line like this

  ffmpeg.exe -hwaccel auto -re -i "C:\Users\Public\Videos\Sample Videos\Wildlife.wmv" -an -sn -c:v bmp -pix_fmt bgr24 -f rawvideo - > junk.bin

  it works fine. However, when I spawn the exact same thing (minus > junk.bin) I get this nasty "bad header" error after a few seconds of playback. What is causing this ? I have trouble believing my process blocks the pipe longer than the filesystem does, but it should be able to block the pipe indefinitely without defeating the decoding. The truncated stderr is below. My code to spawn the thing is here.

• Error with RTSP Stream in Node.js : Could not find codec parameters for stream 0 (Video : h264, none)

  7 août 2023, par theplaceofburak

  I 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

[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 !
