Pro Tip:

NVENC is recommended for most setups. It has a dedicated chip for encoding that won't slow down your recording server.

Common FFmpeg Errors

  • "Unrecognized option 'hwaccel'": Your FFmpeg build might be too old or missing CUDA support.
  • "Failed to set value...": This usually means your hardware doesn't support the requested codec (e.g. H.265 on very old cards).
  • "Permission denied": Ensure your script has write access to the output folder.
