plugin nvenc problem while building gstreamer 1.14.4 from source

[Rand Graham]

Hello,

I can give you two suggestions that you will have to adapt to your specific installation.


1)      IIRC, Nvidia provides documentation and instructions on how to build their plugins. Please check the Nvidia documentation.

2)      On one of my systems I had to specifically set the following environment variable in order for gstreamer to find third party plugins I built from source. Assuming you have compiled the nvidia plugin and gstreamer just needs to find the plugin. Set this appropriately for your system:

export GST_PLUGIN_PATH=/usr/lib/x86_64-linux-gnu/gstreamer-1.0/

Hi, I build gstreamer 1.14.4 plugin bad from source like below:

NVENCODE_CFLAGS="-I/usr/local/cuda/include/" NVENCODE_LIBS="-L/usr/local/cuda/lib64/stubs/" \
    ./configure --prefix=/usr --enable-orc --enable-webrtc \
    --enable-nvenc --with-cuda-prefix=/usr/local/cuda
  time make -j$(nproc)
  make install
The configure is like below:
