A simple program to receive image data from the Lenkeng LKV373 HDMI-extender.

Contents:

setup.sh: Configure specified interface for the TX Unit.

simple_receiver.c: The actual receiver. It provides 25fps of mjpeg via a tcp port configurable with -p. To select the interface that the data should be received on, use the -i command line switch. To compile it, you need libevent-dev. Then, you can use something like this: $ gcc -o simple_receiver simple_receiver.c -levent

fallback.jpg: An image transmitted by simple_receiver when the data received from hdmi grows stale.

Usage:

$ sudo ./simple_receiver -i eth1 -p 81

• -i specifies the interface where the LKV373 is connected
• -p specifies the port on which the mjpeg stream should be served

Troubleshooting: "Could not bind trigger UDP socket: Cannot assign requested address": you must configure the interface first: $ sudo ./setup.sh eth1
