[IDEA] Raspberry Pi 2 and H.265/HEVC?

Most UK users cannot use Torrents for fear of the Internet Police.

My thoughts are that behind the scenes most processing is done in H/W without us knowing it, whilst H.265 is new and not included in the H/W and thus has to be done in S/W. As it has double the compression ration of H.264 there's a lot more processing power required. I'm sure this was true when DTS was announced.

For now, you'd be better off transcoding them to something else. Handbrake is supposed to be able to handle H265.

Off topic: Police really goes after bittorrent client users in the UK? wow thats really petty of them

On topic: H.265 is well documented on this site so if anyone wants to learn a little more about it just follow the link .

And yes it requires dedicated hardware decoders (like the ones on the new GPU's) to free up the CPU... The same goes for the current H.264 (AVC) as we use it on the VideoCore 4 GPU on the Pi (or at least i have that impression lol).

My question here is: is it possible to write code for the VideoCore 4 (is a GPGPU right?) to handle the computation of the new codec? i mean if is the GPU is partially free it could do some of the job no?

Give us some time, but first we need a legal file to test on. The RPi 2 may work (Suck in breath - just like a builder giving a quote)

On the Site you can find several HEVC legal samples to test
