• Use window.innerWidth to detect mobile devices.

  19 avril 2019, par blueimp

  Use window.innerWidth to detect mobile devices.
  Although window.orientation works well to detect mobile devices for now, it is deprecated and might be unreliable.

  Using the viewport size is also a better approach for hiding/showing additional view elements.
  

• How can i specify range of frames in ffmpeg shuffleframes filter [closed]

  26 juillet 2022, par liphone

  I need to duplicate a bunch of seconds in video and in official docs you can only input frames into shuffleframes filter like so

  


  ffmpeg -i  INPUT -vf "shuffleframes=0 1 2 3 4 5 6 7 ... 592 593 594 595 596 597 598 599 600" OUTPUT


  


  Is there any way to put it like in array ? Or maybe other method of shuffling frames in ffmpeg

  


• How to load a custom java module into Wowza Streaming Engine ?

  27 octobre 2018, par kw3rti

  I’ve followed the tutorial below step by step, however, the module I’ve created does not appear to load or execute, as I’m not seeing any log entries relating to the getLogger calls in the Wowza Streaming Engine. More specifically, I have created a new Wowza project containing a new module (see code below). Eclipse has then created a jar file in the lib folder of the install directory. I have added the module to a live application on the streaming server. I have also edited the Application.xml file to include the new module.

  To hopefully run the module I’ve written, I am streaming an mp4 file using ffmpeg (according to documentation here) to the streaming engine (via the live application), which I can see in the test players. My understanding was that this would trigger at least one of the event listeners in the module. However, nothing appears to come up in the logs. The only entries related to the stream that I can see are shown below.

  I’ve been trying to debug what’s going wrong for quite a while now, so I’d appreciate any suggestions of what might fix the issue.
