gstreamer-vaapi

Hi,

I miraculously got it to compile, replacing everywhere it said

# include <GL/gl.h>

with

# include <GL/gl.h>
# include <GL/glext.h>

"sudo make install" put the libraries in /usr/local/lib/gstreamer-1.0

however, simply copying the files libgstnvenc.la  libgstnvenc.so into
/usr/lib/x86_64-linux-gnu/gstreamer-1.0/
or /usr/lib/x86_64-linux-gnu doesn’t seem to install the plugin:

gst-launch-1.0 fakesrc ! nvenc


WARNING: erroneous pipeline: no element "nvenc"

Hi

So you'd have to compile gst-plugins-bad yourself - it's enough to
configure it and then cd sys/nvenc; make; make install in there - no
need for all the other plugins.

Then by default the plugin will be installed into a different prefix,
so you either need to copy it into /usr/lib/../gstreamer-1.0/ manually
or set the GST_PLUGIN_PATH variable to where it was installed, so that
GStreamer finds it.

I’m stuck again, sorry :( . I configured with the nvidia libraries:

LDFLAGS="-L/usr/lib/nvidia-367" ./*configure*
--with-cuda-prefix='/usr/local/cuda’


But building nvenc fails when it tries to make the gl module. Here is the
error when I try to make gl directly:

For what it’s worth, there is a libGL.so in the /usr/lib/nvidia-367
