• Could not write header for output file #0 (incorrect codec parameters ?) : Broken pipe

  23 mai 2020, par Laura

  I'm trying to generate audio waveform from an mp4 file as described here : https://github.com/bbc/audiowaveform.

  



  My mp4 file looks like

  



  <?xml version="1.0" encoding="UTF-8"?>


  



  http://www.w3.org/2001/XMLSchema-instance' ;>
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 


  



  <format filename="/cache/1268.mp4" duration="40.112000" size="10610125">&#xA;    <tag key="major_brand" value="isom"></tag>&#xA;    <tag key="minor_version" value="512"></tag>&#xA;    <tag key="compatible_brands" value="isomiso2avc1mp41"></tag>&#xA;    <tag key="encoder" value="Lavf58.20.100"></tag>&#xA;</format>&#xA;

  



  



  I wrote this command line :
/ffmpeg-4.1.1/ffmpeg -i /cache/1268.mp4 -map 0:1 -f wav - | /opt/audiowaveform/audiowaveform —input-format wav —pixels-per-second 25 -b 16

  



  But it fails with the folliwing error :
Could not write header for output file #0 (incorrect codec parameters ?) : Broken pipe
Error initializing output stream 0:0 —
Conversion failed !

  



  Complete log is :

  Can anyone help me ?

  



  Note : I read the answer here ffmpeg Could not write header for output file #0 but I need to preserve audio codec.

  


• 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 !!

  I tried messing about with the line of code but no success so I turn to you for additional support
