Describe the bug
I've trying downloading the AppImage version of 6.4.0 and running it on your standard-test.mp4 lusing realesrgan as well as realcugan and libplacebo. Only libplacebo produces imagery, the other two I just end up with a really small video of pure black screen.

To Reproduce
Steps to reproduce the behavior:

1. Download the AppImage version 6.4.0 and standard-test.mp4
2. Execute Video2x with this command: ./Video2X-x86_64.AppImage -i standard-test.mp4 -o Upscaled.mp4 -p realesrgan -s 4 --realesrgan-model realesr-animevideov3 (strictly speaking the realesrgan-model doesn't matter, it produces the same either way)

Expected behavior
I'd expect a upscaled video.

Actual behavior
The video is pure black screen.

Environment:

• OS: Fedora 42 KDE
• GPU: AMD RX 9070 XT
• Video2X Version: 6.4.0

Full command
./Video2X-x86_64.AppImage -i standard-test.mp4 -o Upscaled.mp4 -p realesrgan -s 4 --realesrgan-model realesr-animevideov3

Additional context
I did try this with realcugan as well with exactly the same result.
