Variant 1:

Writes the next video frame.

Positional Arguments

• self: Evision.CUDACodec.VideoWriter.t()

• frame: Evision.Mat.

  The framet to be written.

The method encodes the specified image to a video stream. The image must have the same size and the same surface format as has been specified when opening the video writer.

Python prototype (for reference only):

write(frame) -> None
