• FFserver : cannot connect via rtsp

  27 avril 2016, par newfoundstory

  so im currrently trying to stream my windows desktop using ffmpeg into a raspberry pi running ffserver.
  The client software im using needs to use RTSP, however i cannot connect to the stream no matter what i try.
  I even used VLC in the messages it just says it cannot connect to the stream.
  Any help would be greatly appreciated !
  Im attempting to access the stream with rtsp :// 169.254.70.227 :8544/test.flv, as soon as i do it stops the ffmpeg feed

• dashjs can't find initialization segment on manifest.mpd

  30 avril 2016, par Abelardo Mendoza

  I am following this tutorial to stream a WebM. I have no issues running the ffmpeg commands to generate the videos/audio/manifest files but when I try to run it locally, there’s no video or audio at all and dashjs floods the console with :

  Searching for initialization.    
  
  Start searching for initialization.     
  
  Perform init search: http://localhost:8080/video_1280x720_500k.webm    
  
  Perform SIDX load: http://localhost:8080/video_640x360_750k.webm     
  
  Perform SIDX load: http://localhost:8080/video_1280x720_500k.webm 

  Writing that to console until I stop the server. I have tried using other mpd files such as this, which is used on the dashjs quickstart and it plays the video without any problems.

  I used this guide to install the latest version of ffmpeg on Ubuntu 14.04 LTS :

  The index.html has a few changes because dash.js changed the way the player gets initialized.

      
  
          
  
          
  
          <code class="echappe-js">&lt;script src=&quot;http://cdn.dashjs.org/latest/dash.all.debug.js&quot;&gt;&lt;/script&gt;
  
              
          
  

  And here is Chromium’s log file. I’m converting this webm from this site.

  If I missed out any other relevant information or if anyone can guide me into the right direction, please let me know.

  Edit :

  Like Will Law mentioned, using the Shaka Player worked without any issues with my current manifest. Hope this helps anyone else.

• FFmpeg freezes during conversion

  3 mai 2016, par Bruno Siqueira

  I am trying to run a merge between a mp4 video and a m4a audio files. Several other were generated properly, but this one starts and freezes at time 00:02:54.08. If I stop it (ctrl+c) several minutes afterwards, the output.mp4 file have 0 bytes. I do not have a lot of clues why it happens. Anybody experienced something similar ?
