[FEATURE] GPU/Hardware Acceleration

[cmfc31]

Description

Hi Boris! I love your program but I think it's missing a critical feature.

1. GPU/Hardware Acceleration

What problem does this solve?

1. Currently users depend 100% on CPU to generate screenshots and video preview. Users with GPU can't take advantage of their hardware to accelerate these processes. Working to support something like this will make the Hub generation way faster to users with capable hardware.

Proposed Solution

1. For GPU acceleration, not sure if will be possible to implement due to the electron framework.

Thank you @cmfc31 for the suggestion. The screenshot extraction depends entirely on FFmpeg

I don't know enough, but it seems like, from my quick research, "to extract a screenshot from a video using GPU acceleration with FFmpeg, you need a version of FFmpeg compiled with the appropriate hardware acceleration support" 🤔

I could play around to see if there's a way to get an Nvidia FFmpeg and if it works faster on my machine than the CPU version. If so, perhaps I could do two different PC releases 🤔

Apologies for just emailing you moments ago about this same enhancement before even considering there would be a github!

VideoDuplicateFinder has hardware acceleration (both for discrete and iGPU) implemented - maybe worth peeking at how they've done it?

Thank you @fireworksordie - I'll glance at the repository you shared to see if I can improve VHA 👍
