• Video Encoding Apps with GPU Accelleration?
    5 replies, posted
I am curious because I have a GTS 450 in my Linux Mint box, and want to encode videos to x.264 (AVC, m2ts, etc.) but I want to take advantage of the GPU's power like Windows users can. Is there any apps that can do GPU-assisted video encoding? I rather not spend 7 hours shrinking a blu-ray movie to DVD-R.
One week and no replies... Bump.
Can't Handbrake use CUDA? [editline]12th January 2011[/editline] It does not. :sigh:
Handbreak isn't an encoder. It's a graphical front-end for ffmpeg/x264. The actual encoders have not been written for CUDA/OpenCL because it's too much work for too little gain and much of the code that would benefit from being massively parallel as its written makes up a fractional amount of the total computation. Badaboom is the only encoder I know of at the moment (ATI probs has one too, but w/e) and it isn't really that good in terms of quality or relative speed to x264.

I have having to wait over 6 hours for Linux to recode x.264... So much for Linux having an alternative for everything. :jerkbag:

The video card you need to buy rivals the price of the CPU you can get for a comparable speed.
