You might like to know that I've improved the RPi OpenMAX decoder by<br>
reducing the number of frame buffer copies - saving almost 100MB/s on a<br>
1920x1080p@30Hz stream. This should (hopefully) allow you to play your<br>
HD streams without jerkiness. It's not as good as Kodi (yet), but it's<br>
getting closer.<br>

The jessie build will also run on a Pi Zero. The Zero can only cope<br>
with small SD material (memory constraints), but at $5 what do you<br>
expect? I'm working on reducing the memory footprint of the OpenMAX<br>
video renderer and hopefully will have standard SD broadcast TV working<br>
<span>on the Zero.<br>
