Re: Regarding the demo shown at CES 2019

[developers-linux@xxxxxxxxxxxxx]

Hi Ohiwa-san

I have additional questions.
I'm afraid of asking these kinds of basic questions,
but that is because I don't have much experience with h264-live-player and JavaScript.

<List of questions>
　1. Is this done based on the sample code of server-tcp.js ?
　　 * https://github.com/131/h264-live-player/blob/master/server-tcp.js

　2. The decode of H.264 is performed inside javascript of h264-live-player.
     Does that mean it does not use anything like FFmpeg or GStreamer ? 

Regards,
Kikugawa
