• ffmpeg covert yuv to mp4 failed :"Invalid buffer size, packet size"

  3 janvier 2020, par Sean

  Hi I am trying to convert YUV video to a avi formt with the following command :
  "ffmpeg -f rawvideo -vcodec rawvideo -s 512x512 -r 25 -pix_fmt yuv420p -i output3.yuv -c:v libx264 -preset ultrafast -qp 0 output.avi"

  Then I got an error

• lavfi/spp : add "quality" option in runtime change path

  lavfi/spp : add "quality" option in runtime change path
  it's stranage to use option "level" in runtime change path but used
  
  "quality" in option, add "quality" in runtime change path, it's more
  
  intuitive and keep the "level" for compatibility.

• "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 ?
