  • SNAP : Simulation and Neuroscience Application Platform [closed]

    19 avril 2024, par S_S

    Is there any documentation/help manual on how to use SNAP (Simulation and Neuroscience Application Platform)1.

    



    I wanted to run the Motor Imagery sample scenario with a .avi file for the stimulus instead of the image. How can that be done ?

    



    The following error is obtained when using the AlphaCalibration scenario which gives code to play an avi file.Any help appreciated

  • OpenCV linux how to install FFMPEG

    19 janvier 2017, par Thandi Ngamu

    Can someone please help me with a working method on how to install FFMPEG on linux, I have followed several tutorials and they seem to work except after everything FFMPEG is never found in the system, even after several system reboots my last try was from this link Compile FFmpeg on Ubuntu, Debian, or Mint

    I did everything in the tutorial but when i run the man ffmpeg it tells me no manual found and OpenCV too does not detect it, I tried calling the Core.getBuildInformation() and the output was :
