• FFmpeg with multiple output streams

  22 novembre 2018, par William Blake

  I am using ffmpeg to combine an rtsp stream with an audio stream from a usb mic. I would like to stream the combined audio and and video to an RTMP stream and just the audio to an icecast stream simultaneously. I have them working separately but am having difficulty finding the magic combination using the -f tee parameter. It seems like that would be the best way. This was the reference I was trying to use : https://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs

  Here are the separate commands :

  ffmpeg -rtsp_transport tcp -use_wallclock_as_timestamps 1 -thread_queue_size 1024  \
  
  -i "rtsp://RTSP-SERVER-ADDRESS" \
  
  -f alsa -thread_queue_size 1024 -ac 1 -itsoffset 00:00:01.2 -i hw:1,0 \
  
  -vcodec copy -acodec mp3 -ar 44100 -ab 32k -map 0:v -map 1:a -bufsize 12000k \
  
  -f flv 'RTMP-SERVER-ADDRESS'
  
  
  
  ffmpeg -ac 1 -f alsa -i hw:1,0 -acodec mp3 -ab 32k -ac 1 -content_type audio/mpeg -f mp3 icecast://ICECAST-ADDRESS

  However my attempts to combine them have been futile. Any thoughts ?

• SRT protocol not found - Raspbery Pi 4 via ffmpeg

  12 août 2021, par Tim Martin

  We tried to stream from a rasp Pi 4 via SRT, but we got a error : "protocol not found". Our command line is :

  


  ffplay srt://127.0.0.1:9500?mode=listener&latency=20000


  


  We tried the following guides :
https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
how to compile ffmpeg with enabling libsrt
https://www.undergroundnews.dk/index.php/item/107-rtmp-eller-srt-streaming

  


  Those guides worked so far and compiled but we still got the error message.

  


  Do you have any ideas how to get the srt protocol working on a pi via ffmpeg ?

  


• Anomalie #4569 (Nouveau) : Accessibilité, boutons et javascript

  5 octobre 2020

  Il y a 2 types de boutons qui ne répondent peut-être pas aux critères d’accessibilité, à vérifier.

  Bouton « Détails » dans le modèle document_desc¶

  Ce bouton sert à afficher ou masquer les détails complets d’un document.
  Actuellement c’est juste un lien <a></a> sans href et du javascript inline :

  <span class="CodeRay"><span class="tag">span> <span class="attribute-name">class</span>=<span class="string"><span class="delimiter">"</span><span class="content">lien_details bouton link</span><span class="delimiter">"</span></span> 
  
      <span class="attribute-name">onClick</span>=<span class="string"><span class="delimiter">"</span><span class="predefined">$</span>(<span class="local-variable">this</span>).parent().next(<span class="string"><span class="delimiter">'</span><span class="content">.detaillees</span><span class="delimiter">'</span></span>).toggle(); <span class="keyword">return</span> <span class="predefined-constant">true</span>;<span class="delimiter">"</span></span> 
  
      <span class="attribute-name">title</span>=<span class="string"><span class="delimiter">"</span><span class="content">&lt;:medias:details_document_afficher_masquer|attribut_html:</span></span><span class="error">></span>"<span class="error">></span><span class="tag">&lt;:medias:details_document:></span><span class="tag"></span>
  
  </span></span>

  Boutons pour changer le mode d’affichage¶

  Il s’agit des 3 boutons ajoutés en javascript qui permettent de changer le mode d’affichage de la liste des documents liés.
  Ils sont générés en javascript dans gestion_listes_documents.js.
  Là il s’agit d’un simple <span></span>. Un clic dessus toggle des classes sur une cible.

  <span class="CodeRay">
  
  <span class="tag">span> <span class="attribute-name">class</span>=<span class="string"><span class="delimiter">"</span><span class="content">affichages</span><span class="delimiter">"</span></span><span class="tag">></span>
