While raspberry pi license keygen may prove more of an interest for those that understand the math behind it, it is still something of a curiosity for other users. This key will enable a single Raspberry Pi to decode VC-1 video in hardware. Sedra Smith Microelectronic Circuits 6th Edition more. You will need to provide your device's internal 16-digit serial number as part of y.

I've had a bit of a struggle getting this post written, because I have been fluctuating between: 'Wow, Look, that's really great!' And 'Why the heck doesn't that work?' But I think that I have enough of it figured out now to make it useful to others — so here we go.

A bit of explanation is needed first. The creators of the Raspberry Pi initially decided not to include MPEG-2 and VC-1 codecs with every unit. The decision was based on a combination of the cost involved — the licences required would have raised the unit price significantly — and their belief that the Pi would be primarily an educational tool, so there wouldn't be a lot of demand for these codecs. It didn't take long before it was clear that both of those assumptions were wrong; the Pi was wildly popular not only for educational purposes, and especially with the various Media Centre packages the demand for codecs was substantial. My first question when I heard about these codecs was, 'what do I need or want these codecs for'? As I have said many times, I am not a multimedia expert or even enthusiast, so the various formats and decoders often baffle me.

Fortunately, there are a couple of good explanatory posts on the Raspberry Pi website — first, the, and then a, including a nice table that shows what plays and what doesn't with which decoder(s). For my purposes, the important fact was that I needed an MPEG-2 codec to play commercial DVD movies. I know that there are various ways to rip/copy/convert such things so that they might play another way, but besides the fact that I will always choose the path of least resistance — especially when the cost involved is $2 — I simply don't do that kind of thing. My next question was, 'how do I use these codecs'? Obviously they have to be installed somehow/somewhere, but where and how? Figuring that out, and getting it done, turned out to be a bit more trouble than actually buying them.

Read on for details. If you want/need these codecs, all you have to do is go to the and spend a very small amount of money.

You will need the serial number of your Raspberry Pi, because the licence is keyed to it; the order page explains how to read that from the system. The MPEG-2 codec costs £2.40, and the VC-1 codec costs £1.20, including VAT. In fact, the codecs only cost me £2 and $1 — I suppose because I am outside the UK or EU and they removed the VAT from my order. I got an email confirming the order, and another confirming the payment (via PayPal) almost immediately, along with a statement that the licences would be emailed within 72 hours. It actually took a lot less than that; my first order was for MPEG-2 only, made on a Thursday night, and I got the licence key on Friday; the second order, for VC-1, was made on Monday morning, and I got the key that afternoon. To the very kind order-processing people at the Pi Store, I apologise for not ordering both licences at the same time, I was being a bonehead. To others who are thinking of ordering one or the other licence, I strongly suggest that you splurge and spend the extra pound or two to get both licences.

The cost is minimal and the trouble it might save you and the people at the store is non-trivial. What you get from the Pi store is an email containing the licence key, which you need to enter into the config file on your Raspberry Pi. There are three general ways to do this: • If you are running NOOBS, hold down the Shift key while the Pi boots.

That will take you to the Install/Configure menu, with a list of available/installed operating systems. From there you can choose an operating system and then click 'Edit Configuration File'. • If you have another computer with an SD card slot, you can shut down the Pi, remove the SD card and put it into that system and edit the config file from there.
