• "Pixel format 'yuvj420p' is not supported" when converting image to video using CUDA hardware acceleration

  11 février 2020, par laurent

  I’m trying to convert an image to a video using CUDA hardware acceleration but I can’t get it to work.

  The basic command I have is this one :

  ffmpeg -y -hwaccel cuvid -i tests/MediaSamples/portrait_0.jpg -t 10 out.mp4

  And I’m getting this error :

  [AVHWFramesContext @ 0x32d3f00] Pixel format 'yuvj420p' is not supported
  
  [mjpeg @ 0x2d18480] Error initializing a CUDA frame pool
  
  cuvid hwaccel requested for input stream #0:0, but cannot be initialized.
  
  Error while decoding stream #0:0: Invalid argument

  I’ve tried setting the pixel format like so, but that didn’t help :

  ffmpeg -y -hwaccel cuvid -pix_fmt yuv420p -i tests/MediaSamples/portrait_0.jpg -t 10 out.mp4

  I’ve also tried many other flags but can’t get anything to work. Any idea what the issue might be ?

  For information this is the full log :

• FFMPEG not found because FFMPEG-binaries is no longer supported

  17 novembre 2019, par brenan patrick

  I have been attempting to create a Discord bot, but it cannot connect to a voice channel because it gives the errorError: FFMPEG not found. Is there a way to get around using FFMPEG-binaries or an older version that I can install manually ?
