• ffmepg always get broken video streaming from rtsp protocol [on hold]

  6 janvier 2014, par poc

  I'm trying to capture rtsp streaming from Ip Camera by the command

  ffmpeg -t 10 -i  rtsp://172.19.1.42/live.sdp  -ss 00:00:02.500  -c:v copy download.mp4

  However I always get the broken streaming, but if I used the VLC or Qucicktime to watch the RTSP streaming, it worked fine , there was no broken streaming.

  Is there any setting or options for ffmpeg can improve the streaming quality ? Thanks

• I need to create a streaming app Where videos store in aws S3

  27 juillet 2023, par abuzar zaidi

  I need to create a video streaming app. where my videos will store in S3 and the video will stream from the backend. Right now I am trying to use ffmpeg in the backend but it does not work properly.

  


  what am I doing wrong in this code ? And if ffmpeg not support streaming video that store in aws s3 please suggest other options.

  


  Backend

  


  const express = require('express');
const aws = require('aws-sdk');
const ffmpeg = require('fluent-ffmpeg');
const cors = require('cors'); 
const app = express();

//   Set up AWS credentials
aws.config.update({
accessKeyId: '#######################',
secretAccessKey: '###############',
region: '###############3',
});

const s3 = new aws.S3();
app.use(cors());

app.get('/stream', (req, res) => {
const bucketName = '#######';
const key = '##############'; // Replace with the key/path of the video file in the S3 bucket
const params = { Bucket: bucketName, Key: key };
const videoStream = s3.getObject(params).createReadStream();

// Transcode to HLS format
 const hlsStream = ffmpeg(videoStream)
.format('hls')
.outputOptions([
  '-hls_time 10',
  '-hls_list_size 0',
  '-hls_segment_filename segments/segment%d.ts',
 ])
.pipe(res);

// Transcode to DASH format and pipe the output to the response
ffmpeg(videoStream)
.format('dash')
.outputOptions([
  '-init_seg_name init-stream$RepresentationID$.mp4',
  '-media_seg_name chunk-stream$RepresentationID$-$Number%05d$.mp4',
 ])
.output(res)
.run();
});

const port = 5000;
app.listen(port, () => {
console.log(`Server running on http://localhost:${port}`);
});


  


  Frontend

  


      import React from &#x27;react&#x27;;&#xA;&#xA;    const App = () => {&#xA;     const videoUrl = &#x27;http://localhost:3000/api/playlist/runPlaylist/6c3e7af45a3b8a5caf2fef17a42ef9a0&#x27;; //          Replace with your backend URL&#xA;Please list down solution or option i can use here&#xA;    const videoUrl = &#x27;http://localhost:5000/stream&#x27;;&#xA;         return (&#xA;      <div>&#xA;      <h1>Video Streaming Example</h1>&#xA;      <video controls="controls">&#xA;        <source src="{videoUrl}" type="video/mp4"></source>&#xA;        Your browser does not support the video tag.&#xA;      </video>&#xA;    </div>&#xA;     );&#xA;     };&#xA;&#xA;    export default App;&#xA;

  


• nginx video mp4 streaming - jwplayer seeking

  18 juin 2012, par abrahab

  As you can see nginx streaming solution works and return different content-length when flv requested with start parameter :
  http://www.hotgirlscompany.com/1.flv?start=0
  http://www.hotgirlscompany.com/1.flv?start=300000

  But the problem that jwplayer v5 can not seek this video to any position. Seems (from http sniffer) player request ?start=0 and then ignore any mouse clicks at loading line, and can not go to position I want).

  Of course, I added provider=http to flashVars.
  You can download the video and see that its converted as H.264/AAC. Then maked mp4box -inter 500 1.flv. But still can not steam it :(

  Any suggestions ?
  Maybe example how to property reconvert this video with ffmpeg to make it playable ?
