Re: running windows on the raspberry

<t>I tend to agree with Grumpyoldgit.  In the same vein as "If you have to ask the price, then you can't afford it" my opinion is that people who ask if it will run Windows will not  initially have the ability to install an emulator, plus figure out how to load it with Windows from their CD/DVD.<br/...

I expect the bosses at MS can sleep more easily now they know that their plan for continued world domination will not be wrecked by billions of RPs not running their software.

Re: Raspberry Pi Video Encoding...

<t>The key point will be the motion vector estimation.  Apart from that, H.264 is fairly symmetrical - ie encode and decode have similar complexity, operations per second etc.  The encoder processing needed to calculate good motion vectors is massively more than just using them in the decoder.  Non-...
