Gstreamer 1.16 missing nvdec/nvenc

The news gstreamer 1.16 should include nvdec and nvenc plugins (https://gstreamer.freedesktop.org/releases/1.16/#1.16.0)

But they seems to not be present in the archlinux packages

phas@Hyperion ~> gst-inspect-1.0 nvdec
No such element or plugin 'nvdec'
phas@Hyperion ~> sudo find / -name "*nvdec*"

Afaik it should be in gst-plugins-bad. I remember from 1.15 times that it's a bit tricky to get it compiled, so maybe it wasn't?

It wasn't and from the looks deliberately so https://git.archlinux.org/svntogit/pack … a71918#n45 though I don't know the reasoning

Re: Gstreamer 1.16 missing nvdec/nvenc

Probably because it's not simple to get gst-plugins-bad compilation processo to actually detect and use cuda and cudart.

I posted about this on gst-devel mailing list http://gstreamer-devel.966125.n4.nabble.com/

Anyone here that knows how to write a pkg-config file for cuda and cuda-rt?

Re: Gstreamer 1.16 missing nvdec/nvenc

UP. This is still a problem afaik.

After the post on the mailing list, i opened a ticket on the gst-plugins-bad tracker https://gitlab.freedesktop.org/gstreame … issues/966
this was closed but I think that it will be relevant for the next release.

To get nvdec and nvenc compiled for 1.16, I think that we need proper pkg-config files for cuda
