FFMpeg: feeding the video

	Of course you should substitute your own FFServer in the above example. At this point, FFMpeg will begin capturing video from your camera. It'll do the transcoding to the proper format locally and send that off to your server. Leave it to encode for about half a minute and then hit your server's stream URL using Windows Media using this URL: 78.47.18.19/cam1.asf The player will buffer for a bit and your video will start playing. Congratulations, you're done.		Of course you should substitute your own FFServer in the above example. At this point, FFMpeg will begin capturing video from your camera.

	As part of a new hobby project involving real live mice, a couple of webcams and a laptop, I got to spend some time setting up a more or less robust live streaming service. At this point in time the whole setup is offline due to dust accumulating inside the laptop as well as the mice gnawing through too many USB cables. The setup should work in more forgiving environments, though.

	Webcams


			==Webcams==

	This web stream from the inside of a mouse tank needed to be cheap. Mice are very active rodents so they tend to chew on just about anything. Especially at first I didn't want to invest in expensive webcams only to have them chewed to bits in a few hours. My fears were quickly confirmed. As I'm typing this, there's a wireless webcam on the table next to me. Except, this cam actually does need the USB wire so it's broken now thanks to our subjects.

	The cheap model webcam I picked is branded "Tecknet" and is available from Amazon. The biggest selling point to me on this specific model is the group of bright white LED lights installed in the front of the cam. This makes a huge difference in a shady environment like a mouse tank. The LED intensity is controlled by a knob in the wire, so it's independent from the PC control.

	While waiting for a friend's soon to be genrously donated half-broken first generation Acer Aspire One netbook, I decided to hook up a laptop from work. It's a Lenovo T60p, which is much too powerful for this purpose. A simple netbook booted off a USB stick will do just fine.

	Essentially what I needed was a device that can pull video from USB at 640x480x15fps, MPEG4-encode this in real time and push that over WiFi to a remote multiplexer for use by viewers.

Out of the box Ubuntu doesn't ship with any non-free codecs in FFMpeg, but luckily I didn't need those anyway (yet) so I could get away with a simple:

	#apt-get install ffmpeg		apt-get install ffmpeg

	It is actually important to have the exact same FFMpeg package on both the encoder laptop and on the multiplexing server. The FFMpeg and FFServer compontents are very picky about their communications between particular versions. Assuming you have FFMpeg installed on both your server and the laptop, you should begin with the server. The server is the compontent that will later dictate the encoding parameters to the laptop, so make sure you have that set correctly.
