Upscale without needing to extract frames

[BankaiNoJutsu]

Hey!

Is it possible to upscale the frames from memory instead of writing to disk? I was thinking using image2pipe may be an option? (The main ESRGAN has a python example for video files), however the ncnn Vulkan implementation only supports images or directories inputs.

This should speed up the process and decrease read/writes on disk

Just wondering if possible, as this would be a nice improvement.
