I was trying to get Cedrus/libvdpau-sunxi running on mainline. Now, I have something running that remove /dev/ion. I’m using the libvdpau-sunxi (from mosterta) merged with the disp2 featurues from the libvdpau-sunxi (from main sunxi repository). It runs on the legacy H3 kernel (with disp2 enabled). On mainline kernel the video decoder is running without the ability to display anything in realtime.

noblock: yeah, display on the H3 is very much a work in progress at the moment

I have something that can be useful for testing; I've merged the 'de2' driver and the 'disp2' driver (from the kernel 3.10) to run on the mainline kernel. It compiles, it starts without crashing but it does nothing yet...

noblock: wouldn't it make more sense to work on adding the video layer support to de2 ?
<mripard>
at least, it would be upstreamable, and not eventually wasted

<rellla>
noblock, mripard: and adapt libvdpau-sunxi to work with mainline display driver ...
<noblock>
MoeIcenowy: I'm still interested in the patches to run the mali driver on mainline H5. If you have something, I will give a try.
<mripard>
rellla: well, yeah.
<rellla>
but also, this would probably be wasted effort, too. because it would be better to take libva on the userspace side. it seems to be more future-proof
<rellla>
but as a meantime solution ...

Mripard : Indeed, adding this feature is something that is 'upstreamable' on the linux kernel, and is helpful, for one other functionality: Adding a xvideo layer on top of the X11 driver.

rellla: Today we have 3 standards: va, vdpau and the m2m; And, vdpau is still well implemented on the player side.
<rellla>
noblock: it is. but i think va is implemented on the same players, too. if the kernel side is ready, it should not be too hard, to code in the mainline display engine, i think. so libvdpau-sunxi does not have to be abandoned ...
