<br>
yes. ffplay, vlc, mpv, mplayer - all work fine, that's what this<br>
update was about:<br>
<a href="https://www.crowdsupply.com/eoma68/micro-desktop/updates/cedrus" target="_blank">https://www.crowdsupply.com/<wbr>eoma68/micro-desktop/updates/<wbr>cedrus</a><br>
<br>
basically by using the full capabilities of the A20's accelerated<br>
hardware (both CEDAR and G2D), the CPU usage is somewhere around the<br>
10% mark. peanuts in other words.<br>
<br>
the reason why those work is, through vdpau plugins there's two<br>
parts: "decode" part and "actual on-screen display" part. all those<br>
video players have an option to do *both* things, and the vdpau-sunxi<br>
plugin that the Cedrus team wrote goes "okay, we're configured to use<br>
G2D, let's just go for it".<br>
<br>
that's why you end up with the overlay issues, btw, because the G2D<br>
hardware is told to write direct to an area on-screen, bypassing the<br>
X11 protocol.<br>
<br>
anyway, it's *ASSUMED* in the webkit and xulrunner engines that the<br>
"on-screen display" bit can be handled by OpenGL or...<br>
something-else-don't-know-don'<wbr>t-care-but-basically-it's-not.<br>
<br>
and that means a bit of rewriting of both webkit and xulrunner so<br>
that they hand over the display bit to G2D. that's going to require<br>
some specialist work.<br>
