Gstreamer 1.16 NVDEC compile, CUDA path

[RiccardoCagnasso]

How can you compile gstreamer 1.16 with a custom CUDA path to enable
NVDEC/NVENC?

It seems that even the mantainers of archlinux cannot figure out this.

One way might be to create the pkg-config files for cuda and cudart. I tried
and with the correct files, the compiler detects cuda and cudart but I don't
know how to write pkg-config files so that cuda libraries are actually
included.

Also, this might not be ideal for a distribution mantainer.

You have to set CUDA_PATH while building gst-plugins-bad. That should
work. We use that in Cerbero and it works fine:

ubuntu ships with the extra .pc files for cuda/cudart/etc however I have
not seen them available anywhere else.

Cheers

export CUDA_PATH=/opt/cuda definitely doesn't work.

This makes sense because the only occurrence of CUDA_PATH in the whole
repository is

If that doesn't work, please file a bug.
