• How to disable switchable graphics ?

  20 juillet 2021, par Hab-Land0

  Recently, I've updated my graphic drivers for a new system I built, a mix between an amd apu and an nvidia quadro. But I stumbled upon a rare problem, every time I tried to use OpenCl acceleration on ffmpeg for libx264 encoding, ffmpeg notifies me with the next line :

  


  [libx264 @ 0000028149222780] OpenCL acceleration disabled, switchable graphics detected


  


  My obvious step was to search everything I could around this "switchable graphics", but almost all the tutorials on websites told me that I should search around the driver's settings, but literally either Radeon Software or Nvidia's control panel don't display any option about it (It is worth to say that almost all of the tutorials refer to laptops with dedicated graphics and were very outdated).

  


  Another way I use OpenCL is for vapoursynth's filters, such as KNLMeansCL. And, when I make use of this filter, task manager detects that both AMD's APU and Nvidia's gpu are being used simultaneously (I guess that's how the switchable graphics actually works).

  


  My main complain with this is that I attempt to use AMD as a display driver and let Nvidia do the hard work, and I actually was able to do that before updating my drivers. And, talking about the "updates" more in-depth, I updated nvidia's from "462.59" to "471.11" and, unfortunately, I can't remember what versions were my AMD drivers.

  


• ffmpeg adts streaming with ezstream for icecast

  18 avril 2015, par Roberto Arosemena

  I’m trying to use ezstream to stream to an icecast server, my problem is while encoding the audio, I decode it from mp3 with madplay and I’m trying to encode it with ffmpeg so the output is aac, someone told me to use adts to be able to stream aac the problem is that the encoding doesn’t stream the audio, it shows the timer on the console but it goes from 0:00:00 to 0:00:40 to 0:01:30, etc until the song ends instead of going second by second, this is my config :

  <ezstream>
  
     <url>http://localhost:8100/t</url>
  
     <sourcepassword>password</sourcepassword>
  
     <format>MP3</format>
  
     <filename>/home/vybroo/server/audio/play.m3u</filename>
  
     <reencode>
  
        <enable>1</enable>
  
        <encdec>
  
           <format>MP3</format>
  
           <match>.mp3</match>
  
           <decode>madplay -b 16 -R 44100 -S -o raw:- @T@</decode>
  
           <encode>ffmpeg -f s16le -ar 44.1k -ac 2 -i - -b:a 32k -ar 44.1k -f adts -</encode>
  
        </encdec>
  
     </reencode>
  
  </ezstream>

  is the enconding config wrong ?, what should i change so it streams second by second correctly
