Bug ID: 763359
Summary: XDG_RUNTIME_DIR not set in the environment
Classification: Platform
Product: GStreamer
Version: 1.6.0
OS: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: gstreamer-vaapi

GNOME version: ---

I am using gst-rtsp-server-1.2.3 in Ubuntu 14.04 to stream video from webcam to
another laptop. The working gstreamer pipeline that I used is $ sudo
/home/ubuntu/Downloads/gst-rtsp-server-1.2.3/examples/test-launch "v4l2src
device=/dev/video0 ! x264enc tune=zerolatency ! rtph264pay name=pay0 pt=96".
However, the video stream is delayed for 5 seconds. I suspect this might be
caused by CPU encoding, so I try to use gstreamer-vaapi 1.6.0 so that GPU will
do the encoding task. I replace the x264enc with vaapiencode_h264 and the
pipeline becomes $ sudo
/home/ubuntu/Downloads/gst-rtsp-server-1.2.3/examples/test-launch "v4l2src
device=/dev/video0 ! vaapiencode_h264 rate-control=vbr tune=high-compression !
rtph264pay name=pay0 pt=96". But when I run the pipeline, the following error
is shown. Another laptop also not able to open the video stream.

***@ubuntu-lenovo:~$ sudo
/home/ubuntu/Downloads/gst-rtsp-server-1.2.3/examples/test-launch "v4l2src
device=/dev/video0 ! vaapiencode_h264 rate-control=vbr tune=high-compression !
rtph264pay name=pay0 pt=96"

It's libva or the backend that prints this. Please report this against libva,
but it seems more like a setup problem on your system. Ubuntu should've set
this for you already.
