Now I run in ssh session
uv4l --auto-video_nr --driver raspidisp --server-option '--enable-webrtc=yes'I can see on my desktop
As you can see that remote and local window is empty .
How do I debug this issue ?
Thanks.

I saw that on choosing '640x480 30fps' in remote peer options and choosing green call button at the bottom.
I am able to see and listen hdmi output of my raspberry.
To send keystrokes my web browser I had to choose 'send key codes' in data channels.
The best tutorial I found for this is at http://www.linux-projects.org/uv4l/tutorials/play-retropie-in-browser/ . Just use http instead of https in wget commands .
Now my problem that remains is that my gamepad is not detected via web browser ?
Can anybody help me in this.
Thanks.

As said above that my gamepad is not detected when it is connected to laptop instead of raspberry pi .
But when I close emulation station and restart it then screen says ' 1 gamepad detected ' , unfortunately I am unable to configure it as pressing any key on gamepad for long time still has no effect .Has anybody been able to use gamepad on laptop via web browser ?
It is strange that I do not get any response on my posts . I thought there are experts on this forum who can provide helpful suggestion.

I have not connected any gamepad directly to pi.
I found that after bootup the emulation station says no gamepad detected .
Then I connect to it via web browser and choose 'send keycodes' then I press f4 on my laptop keyboard then emulation station exits .
I restart emulationstation - this time it says 1 gamepad detected . Please note that currently my usb gamepad is nowhere in picture . So I assume that emulation station is calling my laptop keyboard as gamepad . The problem is that on pressing any laptop key for long time nothing happens.
I was thinking that at least my keyboard is detected by retropie via browser . So once if I map laptop keyboard to game pad then I will think of mapping my usb gamepad to laptop keys for same effect .
Can you suggest ?Thanks.

I notice that when I connect to pi via web browser
