• 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;

  


• Node Media Server not stream when i try to pass the argument "transpose=1" to ffmpeg

  28 mai 2020, par joao.jlf4

  I'm using node-media-server to stream to instagram, and i need to rotate the original vídeo, to be portrait. I know that there is a flag on ffmpeg called transpose (there is rotate too), but when i pass it on node_relay_session.js on 24 line at the argv array, it returns me a "[Relay end]" on console, and it does'nt stream. When I remove the transpose flag from argv array it backs to stream normaly. Here is my config to nms :

  



  import NodeMediaServer from 'node-media-server';
import removeBarOfRtmpUrl from './utils/removeBarRtmpUrl';
import path from 'path';
import { remote } from 'electron';

export default function(data) {

const streams = data.map(stream => ({
endpoint: removeBarOfRtmpUrl(stream.endpoint),
key: stream.key,
}))

const config = {
rtmp: {
port: 1935,
chunk_size: 60000,
gop_cache: true,
ping: 30,
ping_timeout: 60
},
http: {
port: 8000,
allow_origin: '*'
},
relay: {
// C:\Users\Usuario\Desktop\multistream\node_modules.bin\ffmpeg.exe
ffmpeg: path.join(remote.app.getPath('appData'), '..', 'Local', 'Programs', 'multistream', 'app', 'ffmpeg', 'bin', 'ffmpeg.exe'),
tasks: streams.map(stream => ({
app: 'live',
mode: 'push',
edge: ${stream.endpoint}/${stream.key},

  }))
},
};

const nms = new NodeMediaServer(config);
return nms;
}

// {
// app: 'live',
// mode: 'push',
// edge: 'rtmp://a.rtmp.youtube.com/live2/keyyoutube',
// },```


  


• Android native runtime fails to load symbols even though they are actually found in the loaded .so files

  25 octobre 2017, par Gopinath

  I have compiled ffmpeg v3.4 using NDK v15.2 and I’m creating a wrapper lib called ffmpeg-jni.

  static {
  
      try {
  
          System.loadLibrary("avutil");
  
          System.loadLibrary("avcodec");
  
          System.loadLibrary("avformat");
  
          System.loadLibrary("swscale");
  
          System.loadLibrary("avfilter");
  
          System.loadLibrary("ffmpeg-jni"); // Exception here line#101
  
          loadedLibraries = true;
  
      } catch (Throwable e) {
  
          e.printStackTrace();
  
      }
  
  }

  Below is the exception thrown when loading my wrapper library.

  10-24 11:12:13.819 21499-21499/com.myeglu.android.canary.staging W/System.err: java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "av_register_all" referenced by "/data/app/com.myeglu.android.canary.staging-2/lib/arm/libffmpeg-jni.so"...

  But, to my surprise, this function is defined in libavformat.so, which loaded successfully ; This is clear from the nm tool outputthat the av_register_all() function is defined (T) in libavformat.so

  Here is a link of all the pre-built libraries that are troubling to make peace at runtime. (There are a few other libraries as well apart from the ffmpeg libs)

  Somebody help me understand what I could be missing in this case. Thanks for your time.
