To stream webxr content and save to a file:

GST_PLUGIN_PATH=target/gstplugins \
gst-launch-1.0 -e servowebsrc url=... webxr=left-right \
! video/x-raw\(memory:GLMemory\),framerate=50/1,width=512,height=512,format=RGBA \
! glvideoflip video-direction=vert \
! glcolorconvert \
! gldownload \
! queue \
! x264enc \
! mp4mux \
! filesink location=test.mp4
```
This requires the webxr content to support the `sessionavailable` event for launching directly into immersive mode.
Values for `webxr` include `none`, `left-right`, `red-cyan`, `cubemap` and `spherical`.
