I have already tried to convince Jolla developers to implement x265 HEVC in the design of the new Jolla Tablet and they told me to announce the idea here...
I strongly believe x265 codec is the future one and successor to x264 so anyone who shares the same belief please feel free to submit your view here. It is in the community hands now :-)

I requested HEVC implementation for recording a while ago https://together.jolla.com/question/14402/bad-codec-video-recording-filesize/ encoding something does for a mobile device also mean that it should be able to decode it. Jolla does not seem to be interested in putting effort in what is becoming a requirement of today phones and tablets multimedia wise.
from Ardeno 305 specs I read that it support h264 encoding and HEVC decoding, nothing about encoding support, but a step up from 263->264 could make a huge difference as you could use the freed juice for additional processing - but yes, by the size of jolla... and for the tablet the specs are equally bad, did not find anything more promising, otoh the camera is just above the resolution of the display so not to expect much at all no matter what codec - no HDMI out means also no need for 4k output... which is actually supported

I completely agree. Within the next months hevc will be the most used codec in the web.

ApB ( 2015-04-27 16:13:34 +0300 )editI'm not too sure if HEVC is the future. Isn't the MPEG LA competing with another body to handle licenses? VP9 is a strong contender, with much easier licensing. And Xiph's Daala codec is also still being worked on, which should be totally free of potential patent issues.
A HEVC HW decoder license might be worth the price, depending on the price. But I'd strongly prefer to use VP9 (or even VP8) for encoding, and save some license money.
Also, the CPU will be too weak to handle HEVC in software at full HD, or at least to inefficient. But what about a GPGPU (OpenCL) software solution?
Fuzzillogic ( 2015-04-27 16:21:21 +0300 )edit@Fuzzillogic The phone can't handle it and doesn't have HW for it. You cannot do certain video staff with gpgpu so it won't be possible.
However i expect the tablet to support them through HW.
ApB ( 2015-04-27 16:41:49 +0300 )edit@ApB There certainly are decoders for AVC and HEVC using GPGPU. Heck, ARM wrote one for Mali GPU's. OpenCL on Jolla might be possible.
