• ffmpeg - how to pass all streams audio/tmcd, etc from input->output unchanged

  22 avril 2021, par QRrabbit

  Please help me, with hopefully specific ffmpeg arguments to include in my video encoding.

  


  My work is only related to video stream, so this is the only one I'm changing.
I receive a .mov file(s) that have already been pre-compiled for a specific broadcaster, some of those selfcontained videos have 4 streams (1 video, 2 audio, and some other timecode stream). Others have up to 17 streams : 1-video, 15-audio streams and the final one is unsupported tmcd.

  


  My process pipeline includes only re-encoding/re-processing video stream, and everything else I need to pass along to the output file - all other streams without any changes or alterations.

  


  During this step of encoding, I insert icon.png into position 5:21 from sec 2-3, from 4-5, and from 6-8. To achieve this, I use map option, so my encoding string looks like this :

  


  ffmpeg -i in.mov -i icon.png -i icon.png -i icon.png
    -filter_complex "  [0][1]overlay=5:21:enable='between(t,2,3)'[v1];
                      [v1][2]overlay=5:21:enable='between(t,4,5)'[v2];
                      [v2][3]overlay=5:21:enable='between(t,6,8)'[v3]" -map '[v3]' -map 0:a
    -c:v dvvideo -pix_fmt yuv422p -b:v 115084915 -maxrate 115084915 -minrate 115084915 -r 29.97 -top 1 -color_primaries bt709 -color_trc bt709 -colorspace bt709 -vtag dvh6
    -c:a copy -c:s copy -y out.mov


  


  The problem is that the out.mov only shows with 2 streams instead of 17 (1-video, and 2-audio). All other 15 streams are truncated completely.
Reading some other stackoverflow posts I found a way to transfer all other streams, is by using -map 0 :

  


  But as I tried adding -map 0 on my last line :

  


      ...
    -map 0 -c:a copy -c:s copy -y out.mov


  


  but this doubles the number of streams from 17 to 34 - also double in output file size.
If I remove map '[v3]' -map 0:a from my original encoding string and only include -map 0, I get correct number of streams, but, of course icon.png is not getting inserted at the right time. What should I do ?

  


  If there's a way to re-map my -filter_complex to overlay images without using this -map option ? Or, be specific at what each -map referring to ?

  


  If not, what other arguments/parameters can I use, if such option even exists, to copy all streams, subs and all other audio, potentially some other signal for audio impairment, if such exists.

  


  Please help, so I can finally wrap my output and submit my work.

• Duplicated frames when mering multiple videos with xfade filter (ffmpeg)

  25 février 2021, par tjk

  I'm stuck with merging multiple videos with audio. This used to work on most videos I merged before but with some videos, I get the "More than 1000 frames duplicated" warning, and the output video is broken (some videos won't play, just static picture and the sound is misaligned).

  


  All videos are in the same format afaik. The only difference I see is that some are "yuvj420p(pc)" and most are "yuv420p". But I tried merging without those with "yuvj420p(pc)" and it didn't help.

  


  Already tried adding "-vsync vfr", didn't help too.
Interestingly — if I remove the second or the last input video, no warning is given and it all works.

  


  The command I use :

• I received connection refused error while trying to stream live video through RTMP with FFMPEG

  25 septembre 2020, par Femzy

  I am working on a nodeJs app that can send camera stream to third party plartform i.e Facebook and Youtube using the RTMP protoco ;.. It works well on my localhost but once i deploy to the server, it only give me errors. The error I get is below on this content..
Here is my codes

  


  server.js

  


  


  


  const child_process = require('child_process'); // To be used later for running FFmpeg
const express = require('express');
const http = require('http');
const WebSocketServer = require('ws').Server;

const app = express();
const server = http.createServer(app).listen(4000, () => {
  console.log('Listening...');
});

// Serve static files out of the www directory, where we will put our HTML page
app.use(express.static(__dirname + '/www'));


const wss = new WebSocketServer({
  server: server
});
wss.on('connection', (ws, req) => {
  
  
  
  const rtmpUrl = 'rtmp://a.rtmp.youtube.com/live2/MyStreamId';
  console.log('Target RTMP URL:', rtmpUrl);
  
  // Launch FFmpeg to handle all appropriate transcoding, muxing, and RTMP.
  // If 'ffmpeg' isn't in your path, specify the full path to the ffmpeg binary.
  const ffmpeg = child_process.spawn('ffmpeg', [
    // Facebook requires an audio track, so we create a silent one here.
    // Remove this line, as well as `-shortest`, if you send audio from the browser.
    //'-f', 'lavfi', '-i', 'anullsrc',
    
    // FFmpeg will read input video from STDIN
    '-i', '-',

  On the server.js file i create a websocket to receive stream data from the client side and then use FFMPEG to send the stream data over to youtube via the RTMP url

  


  Here is my client.js code

  


  


  


  const ws = new WebSocket(
             'wss://my-websocket-server.com'

        );
         ws.addEventListener('open', (e) => {
             console.log('WebSocket Open', e);
             drawVideosToCanvas();
             mediaStream = getMixedVideoStream(); // 30 FPS
             mediaRecorder = new MediaRecorder(mediaStream, {
               mimeType: 'video/webm;codecs=h264',
               //videoBitsPerSecond : 3000000000
               bitsPerSecond: 6000000
             });

             mediaRecorder.addEventListener('dataavailable', (e) => {
               ws.send(e.data);
             });
             mediaRecorder.onstop = function() {
              ws.close.bind(ws);
              isRecording = false;
              actionBtn.textContent = 'Start Streaming';
              actionBtn.onclick = startRecording;
             }
             mediaRecorder.onstart = function() {
              isRecording = true;
              actionBtn.textContent = 'Stop Streaming';
              actionBtn.onclick = stopRecording;
              screenShareBtn.onclick = startSharing;
              screenShareBtn.disabled = false;
             }
             //mediaRecorder.addEventListener('stop', ws.close.bind(ws));

             mediaRecorder.start(1000); // Start recording, and dump data every second

           });

  


  


  



  On my client.js file, i captured users camera and then open the websocket server to send the data to the server.. Every thing works fine on local host expect for when i deploy it to live server..
i am wondering if there is a bad configuration on the server.. The server is Centos 7.8 and the app was runing on Apache software
Here is how i configured the virtual host for the websocket domain

  


  


  


  ServerName my-websocket.com

  RewriteEngine on
  RewriteCond %{HTTP:Upgrade} websocket [NC]
  RewriteCond %{HTTP:Connection} upgrade [NC]
  RewriteRule .* "ws://127.0.0.1:3000/$1" [P,L]

  ProxyPass "/" "http://127.0.0.1:3000/$1"
  ProxyPassReverse "/" "http://127.0.0.1:3000/$1"
  ProxyRequests off

  


  


  



  I don't know much about server configuration but i just thought may be the configuration has to do with why FFMPEg can not open connection to RTMP protocol on the server.

  


  here is the error am getting

  I will really appreciate if I could get some insight on what may be causing this issue or what i can do to solve it..Thanks in advance..
