[HDMI2USB #14] Supporting Marvell Ethernet chip on Digilent board about getting-started HOT 5 CLOSED

I think we should rename this to HDMI to TCP/IP.

The device needs to be assigned an IP (I would hope dhcp) and a connection to another process running on another network device.

Currently dvsource-firewire connects to dvswitch. DV data is read from firewire and sent to dvswitch. http://dvswitch.alioth.debian.org/wiki/

When I pug a webcam into a PC, I can run an app (like xawtv or camorama) to view the video stream the webcam is generating. There are drivers that the OS manages to take data from the usb port and expose it as a generic video devcie. the app will read from that API.

We need something similar. My idea of a test would be using
pngenc (from http://gstreamer.freedesktop.org/documentation/plugins.html ) which implies that there is a gstreamer plugin (best if existing, but custom if needed) that will read data from the network connection. for instance uridecodebin might be an appropriate plugin.

Here is a reference example of something that sends video on 127.0.0.1

gst-launch-1.0 videotestsrc is-live=true pattern=18 ! avenc_mjpeg ! rtpjpegpay ! udpsink host=127.0.0.1

And something that connects and receives:

gst-launch-1.0 udpsrc uri=udp://127.0.0.1:5004 caps="application/x-rtp" ! queue ! rtpjitterbuffer ! rtpjpegdepay ! queue ! avdec_mjpeg ! videoconvert ! videoscale ! autovideosink

The goal is for the hdmi hardware to replace the first command, and the 2nd command should be able to connect to the device and display the video stream.
