Hi,
I'm happy to announce that we now partially support the Raw Sockets API
[1] on Crosswalk upstream. TCPSocket and TCPServerSocket are very
functional at the moment, UDP will come next.
There is a nice demo based on jsmpeg [2] that I was using to test the
API throughput. It will open a TCP server on your browser and will
render any MPEG1 stream you pump to it. Yeah, it will decode the MPEG1
using JavaScript and render in a canvas element. I was surprised with
the almost "realtime" performance even when testing on a phone.
You can try it by yourself on Linux, using the latest Crosswalk:
$ xwalk http://tmpsantos.com.br/stuff/jsmpeg
Stream from a webcam if you have one:
$ ffmpeg -s 320x240 -f video4linux2 -i /dev/video0 -f mpeg1video
tcp://127.0.0.1:6668
Or stream from your X root:
$ ffmpeg -f x11grab -s [your screen resolution] -i :0.0 -s 320x240 -f
mpeg1video tcp://127.0.0.1:6668
Enjoy and please report the bugs. Most important, don't reply telling me
there are better ways of implementing realtime video communication in a
browser, keep in mind this is a just "why not?" type of demo. :)
