• PHP Create video thumbnail with FFMPEG - returns error code 1

  27 février 2013, par Light

  I am trying to create a video thumbnail with FFMPEG using the following script.
  However I am getting return value of 1. What does it mean ? What is error code 1 ? I have Googled it and didn't find and answer. Thanks.
  Here is the code :

  <?php
  
  
  
          //thumb path should be added in the below code
  
          //test for thumb
  
          $dir_img='uploads/';
  
          $mediapath='thumb.jpg';
  
          $file_thumb=create_movie_thumb('test.mp4',$mediapath,$mediaid);
  
  
  
          $name_file=explode(".",$mediapath);
  
          $imgname="thumb_".$name_file[0].".jpg";

• Shaka Player returns 4001 error - Node.js local web server playing MPEG-DASH

  27 mai 2020, par salgarji

  I've used Chrome inspection tool to access 'Console' and analyze what is happening. Complete error information :

  



  D {severity: 2, category: 4, code: 4001, data: Array(1), handled: false}
category: 4
code: 4001
data: Array(1)
0: "http://localhost:8080/dash_segmentos/video.mpd"
length: 1
__proto__: Array(0)
handled: false
severity: 2
__proto__: Object


  



  My Server.js file :

  



  var http = require('http');
var fs = require('fs');

console.log(__dirname);

var path='dash_segmentos/video.mpd';
fs.access(path, fs.constants.R_OK | fs.constants.W_OK, (err) => {
    if (err) {
        console.log("%s doesn't exist", path);
    } else {
        console.log('can read/write %s', path);
    }
});

const PORT=8080; 

fs.readFile('./player.html', function (err, html) {

    if (err) throw err;    

    http.createServer(function(request, response) {  
        response.setHeader("Access-Control-Allow-Headers", "authorization, content-type");
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
        response.writeHeader(200, {"Content-Type": "text/html"}); 
        response.write(html);  
        response.end();
    }).listen(PORT);
});


  



  As you can see I've added CORS (I guess it's correct) and a console.log to see if it's in the proper location. Furthermore, I've verified that file is accessible with fs.access and it returns can read/write dash_segmentos/video.mpd For this reason, I'm sure I am in the correct path and referencing the right file.

  



  The HTML code (player.html) provided to Server.js :

  



  &#xA;&#xA; &#xA; <code class="echappe-js">&lt;script type=&quot;text/javascript&quot;&amp;#xA;src=&quot;https://cdnjs.cloudflare.com/ajax/libs/shaka-player/2.5.11/shaka-player.compiled.js&quot;&gt;&lt;/script&gt;&#xA; &#xA; &#xA;

  I've tried changing the URL to an online resource and the player is properly working.

  



  My fluent-ffmpeg command which generates the video is :

  



  var ffmpeg = require('fluent-ffmpeg');

var grabacion = new ffmpeg();

grabacion.addInput('0')
.inputOptions(['-y -nostdin', '-f avfoundation', '-video_size 1280x720', '-framerate 30'])
.outputOptions(['-vcodec libx264', '-keyint_min 0', '-g 100', '-map 0:v', '-b:v 1000k', '-f dash',
 '-use_template 1', '-use_timeline 0', '-init_seg_name video0-$RepresentationID$-$Number$.mp4',
 '-media_seg_name video0-$RepresentationID$-$Number$.mp4','-single_file 0', '-remove_at_exit 0', '-window_size 20', '-seg_duration 4'])
.output('/path/to/files/dash_segmentos/video.mpd')
.run();


  



  The mpd manifest file is :

  



  &lt;?xml version="1.0" encoding="utf-8"?>&#xA;<mpd xmlns="urn:mpeg:dash:schema:mpd:2011" profiles="urn:mpeg:dash:profile:isoff-live:2011" type="static" mediapresentationduration="PT26.7S" maxsegmentduration="PT4.0S" minbuffertime="PT13.2S">&#xA;    <programinformation>&#xA;    </programinformation>&#xA;    <servicedescription>&#xA;    </servicedescription>&#xA;    <period start="PT0.0S">&#xA;        <adaptationset contenttype="video" startwithsap="1" segmentalignment="true" bitstreamswitching="true" framerate="30000/1001" maxwidth="1280" maxheight="720" par="16:9">&#xA;            <representation mimetype="video/mp4" codecs="avc1.7a001f" bandwidth="1000000" width="1280" height="720" sar="1:1">&#xA;                <segmenttemplate timescale="1000000" duration="4000000" initialization="video0-$RepresentationID$-$Number$.mp4" media="video0-$RepresentationID$-$Number$.mp4" startnumber="1">&#xA;                </segmenttemplate>&#xA;            </representation>&#xA;        </adaptationset>&#xA;    </period>&#xA;</mpd>&#xA;

  



  Is something about ffmpeg ? Permissions ? Pixel format ? Encoding ? I've tried with other mpd file provided by my Raspberry Pi using video4linux (v4l) and it returns the same error !

  



  I know that's a lot of code, but maybe you find it quicker than me. I guess it's a Shaka Player thing with the XML, but I can't explain how ffmpeg is wrongly creating XML code.

  



  Thank you in advance !!

  


• Streaming to YouTube using FFmpeg Problems

  9 mai 2016, par jason

  I am trying to stream to a live event I have created inside of YouTube. I am trying to stream a already created video. The command I am using is noted below.

  The problem I have is that YouTube is showing the Streaming status as good (picture attached) and it seems to be receiving the data. But there is no sound and no picture in the live event. I’m not sure what the issue could be.

  ffmpeg -re -y -i input.mp4 -vcodec libx264 -b:v 600k -r 25 -s 640x360 -filter:v yadif -ab 64k -ac 1 -ar 44100 -f flv "rtmp://a.rtmp.youtube.com/live2/KEY"

  Edit -

  I have now tested the following codes but I still dotn get any picture or sound.. but the health status in youtube still shows good

  I ran this command first

  ffmpeg -i input.mp4 -vcodec libx264 -preset medium -maxrate 3000k -bufsize 6000k -vf "scale=1280:-1,format=yuv420p" -g 50 -acodec libmp3lame -b:a 128k -ac 2 -ar 44100 file.flv

  and then I ran this

  ffmpeg -re -i file.flv -codec copy -f flv rtmp://a.rtmp.youtube.com/live2/<key>
  
  </key>

  I still didnt get any picture

  I also tried the full command in 1

  ffmpeg -re -i input.mp4 -vcodec libx264 -preset veryfast -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv rtmp://a.rtmp.youtube.com/live2/<key>  
  
  </key>

  still no joy
