[FFmpeg-user] How to use nvida GPU

[hans gerte]

Hi, need some help. i read a lot of forums and googled it, but i got more
confused.
i have a Ubuntu 14.04 running ffmpeg 3.4 (From add-apt-repository
ppa:mc3man/trusty-media).
and now i just bought 2 Nvidia Quadro P5000.
the part that i don't know and need some help on is:
for it to work is it enough that i install the drivers Linux X64 v. 410.78 (
https://www.nvidia.com/Download/driverResults.aspx/140135/en-us)
or do i also need to install the NVENC SDK 8.2
and do i need to build ffmpeg from scratch. and some guide tells that i
also need the CUDA Utillty.

so could some please help me out or even write me a step by step?

Hi,

1) Yes, you need to install the nVidia Linux driver.
2) Yes, you need too to install the CUDA SDK (I recommend a the recent version).
3) And Yes, you need to compile ffmpeg from scratch.

After you installed all, it's quite simple to compile from scratch:
- "export PATH=$PATH:/usr/local/cuda-8.0/bin" (or your newer version).
- "./configure --enable-cuda --enable-cuda-sdk --enable-nonfree --enable-cuvid --enable-nvenc --extra-cflags=-I/usr/local/cuda/include/ --extra-ldflags=-L/usr/local/cuda/lib64/ .." (add here your specific flags).
- "make"

Enjoy!

You don't say what you want to do with FFmpeg and your GPUs.
"to work" is not very precise...
