title: Using ffmpeg without hardware acceleration (C++)
body: <p>I'm working on an application (c++/Linux) that uses the ffmpeg 3.4 libraries to do video encoding. Since version 3.3 hardware acceleration is enabled by default if the platform supports it. The graphics card in my dev system has hardware acceleration support, but the tool also has to run on older systems that do not.
  How can i configure ffmpeg to disable hardware acceleration for video encoding? There is a ton of info about enabling, but i just cant find how to disable it.</p>
  
  <p>ps.
  There already is a similar question: <a href="https://stackoverflow.com/questions/41448442/how-to-turn-off-ffmpeg-hardware-acceleration">How to turn off ffmpeg hardware acceleration</a> but its a year old and unfortunately still unanswered.</p>
