Building nvenc on Ubuntu 16.04

Took me a while to figure out, here’s a guide on building nvenc on Ubuntu 16.04:

  • apt-get install nvidia-cuda-dev nvidia-361 git pkg-config bison flex
  • apt-get build-deps gstreamer1.0-plugins-base gstreamer1.0-plugins-bad
  • download the 6.0 version of the nvidia video codec sdk (the Ubuntu 16.04 most recent driver is currently too old for the 7.0 version), unzip the sdk, copy the headers to /usr/local/include (sudo cp nvidia_video_sdk_6.0.1/Samples/common/inc/* /usr/local/include)
  • build a gst-uninstalled environment (see arun’s guide for instance), compiling gstreamer, gst-plugins-base should suffice
  • compile gst-plugins-bad with:
LDFLAGS="-L/usr/lib/nvidia-361/" ./configure --disable-gtk-doc --with-cuda-prefix="/usr"

Check that it’s working:

gst-launch-1.0 videotestsrc ! nvh264enc ! fakesink

Remember that the GPU must be Maxwell or Kepler (Fermi only supports decoding).

Many thanks to ystreet for his help on getting this right !

The theoretical proper way is the following, but it does not compile (see #772688) :

NVENCODE_CFLAGS="-I/home/user/src/nvidia_video_sdk_6.0.1/Samples/common/inc" NVENCODE_LIBS="-L/usr/lib/nvidia-361/" ./autogen.sh --disable-gtk-doc --with-cuda-prefix="/usr" && make
