• Unbound variable error when installing ffmpeg on openshift online

  31 août 2016, par sinabakh

  I followed the steps on https://forums.openshift.com/ffmpeg but when performing make install I got this error :

  And It’s the install file(which gives error) :

  #!/bin/bash -eu
  
  
  
  source $OPENSHIFT_CARTRIDGE_SDK_BASH
  
  
  
  case "$1" in
  
       -v|--version)
  
       version="$2"
  
  esac
  
  
  
  echo "$version" > ${OPENSHIFT_PYTHON_DIR}env/OPENSHIFT_PYTHON_VERSION
  
  
  
  mkdir -p ${OPENSHIFT_PYTHON_DIR}template
  
  
  
  # Call the version specific install script
  
  exec ${OPENSHIFT_PYTHON_DIR}usr/versions/${version}/bin/install $version

  So what is the problem ? And how can I solve it ?
  thanks

• HTML5 Progressive Streaming — no follow-up range requests

  20 septembre 2023, par user2333829

  I'm working on an embedded device that is recording video on the fly. I'd like to stream that to an HTML5 video element, using our own custom server. I have this almost working and would like some help.

  



  So far as I can tell, I've got libav / ffmpeg doing their job right. I encoded an mp4 in RAM with the moov atom at the start of the file. I've written this file to disk and it plays everywhere it should.

  



  The problem, I think, lies with how I'm responding to HTTP range requests. When I try to do a live stream, I get an initial range request from the browser / player (currently tried Chrome, Firefox, and VLC) for bytes:0-. I responded with some initial bytes. The browser / player actually plays this fine, but never asks again. So the live stream doesn't work, just the first 3 seconds or whatever.

  



  I've looked at the RFC spec of partial content, and my understanding is I'm doing what I should be... Clearly I'm not though. Here is an example of a request / response with Chrome as the requester :

  



  ---

  



  
get /live.mp4 HTTP/1.1
host: localhost:1235
connection: keep-alive
accept-encoding: identity;q=1, *;q=0
user-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.167 Safari/537.36
accept: */*
dnt: 1
accept-language: en-GB,en-US;q=0.9,en;q=0.8
range: bytes=0-


  



  
HTTP/1.1 206 Partial Content
Accept-Ranges: bytes
Content-Type: video/mp4
Content-Length: 182400
Content-Range: bytes 0-182399/*


  



  ---

  



  Again, with that request / response pair, Chrome plays the first 182400 bytes but never makes a second request. I thought having the '*' in Content-Range would make this happen...

  


• Video encoding and decoding by the player during online playback [closed]

  10 janvier 2024, par rahkarenovin

  I made a player to stream the video.

  


  I want to do 32-bit encoding on the video with the help of ffmpeg.
so that the video will only play in my player.

  


  The problems I have :

  


  


  1. I want to put my 32-bit password in the player, the player will check this password while playing the video, if the password is the same, the video will be played.

     


  


  2. I don't know how to decode the video with the below player.

     


  


  


  What code is needed ? What command can I use to decode the video ?

  


  My player code :

  


  <div class="grid">&#xA;    <main>&#xA;        <div>&#xA;            &#xA;            &#xA;        </div>&#xA;    </main>&#xA;</div>&#xA;&#xA;<code class="echappe-js">&lt;script&amp;#xA;    type=&quot;text/javascript&quot;&amp;#xA;    src=&quot;https://cdn.polyfill.io/v2/polyfill.min.js?features=es6,Array.prototype.includes,CustomEvent,Object.entries,Object.values,Math.trunc&quot;&amp;#xA;    crossorigin=&quot;anonymous&quot;&amp;#xA;&gt;&lt;/script&gt;&#xA;&#xA;&lt;script type=&quot;text/javascript&quot; src=&quot;https://cdn.plyr.io/3.5.2/plyr.js&quot;&gt;&lt;/script&gt;&#xA;&#xA;&lt;script type=&quot;text/javascript&quot; src=&quot;https://cdn.jsdelivr.net/npm/hls.js@latest&quot;&gt;&lt;/script&gt;&#xA;&#xA;&lt;script&gt;&amp;#xA;    const source = &amp;#x27;https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8&amp;#x27;;&amp;#xA;    const player = new Plyr(&amp;#x27;#player&amp;#x27;);&amp;#xA;    var video = document.getElementById(&amp;#x27;player&amp;#x27;);&amp;#xA;    if(Hls.isSupported()) {&amp;#xA;       var hls = new Hls();&amp;#xA;       hls.loadSource(source);&amp;#xA;       hls.attachMedia(video);&amp;#xA;       hls.on(Hls.Events.MANIFEST_PARSED,function() {&amp;#xA;           video.play();&amp;#xA;        });&amp;#xA;    }else if (video.canPlayType(&amp;#x27;application/vnd.apple.mpegurl&amp;#x27;)) {&amp;#xA;       video.src = source;&amp;#xA;       video.addEventListener(&amp;#x27;loadedmetadata&amp;#x27;,function() {&amp;#xA;           video.play();&amp;#xA;        });&amp;#xA;    }&amp;#xA;&lt;/script&gt;&#xA;
