Environment

  • Ubuntu 18.04
  • NVIDIA driver 430.40
  • NVIDIA Video Codec SDK 9.0.20

Steps

  1. Clone the gst-plugins-bad and check out to the same version as GStreamer
git clone git://anongit.freedesktop.org/gstreamer/gst-plugins-bad
cd gst-plugins-bad/
git checkout 1.14.0
  1. Download NVIDIA Video Codec SDK and copy header files
cd /path/to/video/codec/sdk
cp /usr/local/cuda/include/cuda.h /path/to/gst-plugins-bad/sys/nvenc
cp include/nvEncodeAPI.h /path/to/gst-plugins-bad/sys/nvenc
cp include/cuviddec.h /path/to/gst-plugins-bad/sys/nvdec
cp include/nvcuvid.h /path/to/gst-plugins-bad/sys/nvdec
  1. Build plugins
cd /path/to/gst-plugins-bad
NVENCODE_CFLAGS="-I/path/to/gst-plugins-bad/sys/nvenc" ./autogen.sh --with-cuda-prefix="/usr/local/cuda"
cd sys/nvenc
make
sudo cp .libs/libgstnvenc.so /usr/lib/x86_64-linux-gnu/gstreamer-1.0/
cd ../nvdec
make
sudo cp .libs/libgstnvdec.so /usr/lib/x86_64-linux-gnu/gstreamer-1.0/

Thanks for your correction.
These plugins in my PC is fine as follows:

$ gst-inspect-1.0 | grep nvenc
nvenc:  nvh264enc: NVENC H.264 Video Encoder
$ gst-inspect-1.0 | grep nvdec
nvdec:  nvdec: NVDEC video decoder

Could you check the installation location prefix of your GStreamer by where gst-inspect-1.0? Mine is /usr instead of /usr/local, so the plugin directory is /usr/lib/x86_64-linux-gnu/gstreamer-1.0/. Maybe your installation has another location.

Or you can check if these two plugins are blacklisted by gst-inspect-1.0 -b.
