using cefsrc in a docker container with GPU acceleration

[Sid Sethupathi]

Has anyone run cefsrc in a docker container with Nvidia GPU acceleration
working? I have a Docker setup that works for using other Nvidia
accelerated gstreamer elements (like nvenc) but I'm unable to get cefsrc to
be hardware accelerated using a similar setup. When I load "about://gpu",
this is what I see:

I'm guessing it is because xvfb-run is being used as the X environment that
CEF needs, and xvfb-run doesn't support hardware acceleration. Has anyone
gotten something like x11docker to work?

For reference, I'm running the container with `--gpus all` and can use
nvidia-smi from within the container. I've set "gpu=true" on cefsrc as
well. This is the entrypoint I'm using

"xvfb-run -s '-screen 0 1920x1080x24' gst-launch-1.0 rtpbin name=rtpbin
mpegtsmux name=mux ! rtpmp2tpay ! rtpbin.send_rtp_sink_0
rtpbin.send_rtp_src_0 ! udpsink host=$MCAST_GROUP port=$RTP_PORT ttl-mc=16
rtpbin.send_rtcp_src_0 ! udpsink host=$MCAST_GROUP port=$RTCP_PORT
ttl-mc=16 audiotestsrc wave=4 ! avenc_mp2 ! mux. cefsrc gpu=true
sandbox=false do-timestamp=true log-severity=1

Thanks,
