I am trying to add a vaapienc_h264 based pipeline to my python3 rtsp server.

I get following error:

my launch description for the rtsp server looks like this:

I added myself to the video group. The same pipeline piped to a udpsink
works without any problems.
The difference is that va_getDriverName() returns 0 on the second try...

/vainfo:/ (I am not running an x server ;))

I am on CentOS7
Kernel: 3.10.0-693.5.2.el7.x86_64
CPU:         Intel(R) Core(TM) i5-4250U CPU @ 1.30GHz
GStreamer 1.10.4

Any suggestsions?
