[11:04:31] stuarta: hmmm, fixing the vaapi under wayland may not be as complex as i first thought.
[11:06:27] stuarta: sample code i've done, shows that if you open a connection to xwayland via the wayland protocol, rather than x protocol, vaapi will initialize correctly
[11:09:37] stuarta: as a proof of concept, it's proved the point
[11:10:36] stuarta: as a proper implementation it sucks. error handling? what error handling
[11:17:22] ** stuarta says "lightbulb" **
[11:21:01] stuarta: great, now the code works for both f25 and f26, uses wayland on f26, x11 on f25, and vaapi initializes in both cases
[11:21:29] stuarta: https://github.com/stuarta/opengl-qt5 <- here is anyone is interested
[12:09:47] stuarta: knew it couldn't be that easy

[14:13:35] ** gigem congratulates stuarta on his perseverance. **
[14:17:38] stuarta: heh
[14:17:48] stuarta: i want my vaapi back
[14:18:33] stuarta: gigem: i'm sure it'll bite more people in the future
[14:19:50] gigem: I wouldn't be surprised. Fix one thing break two others!
[14:20:42] stuarta: nah, they've remove DRI2 support from xwayland in favour of DRI3, but libva via x connection to wayland, needs DRI2
[14:21:00] stuarta: whilst libva to wayland as a wayland client, appears to work
[14:21:37] stuarta: noticed DRI2 had disappeared from the xdpyinfo output on my f26 system where vaapi doesn't work in mythtv anymore
[14:23:33] gigem: Good spelunking.
[14:24:11] stuarta: the more i look into it, the more we have to pull apart some basic assumptions in our code
[14:25:44] stuarta: i have a feeling, i'll end up with an unnatural familiarity with the internals of our graphics stack
[14:29:06] gigem: I think we have our new graphics expert.  :)
[14:33:15] stuarta: pfft
[14:33:28] ** stuarta points at peterbennett **
[14:37:42] stuarta: i'm am absolute beginning at this stuff
[14:41:54] gigem: Well, that far beyond me! :) Although, I'm fighting the urge to pick up an Nvidia Shield. If I lose that battle, there will probably be Openmax in my future.
[14:42:13] stuarta: vulkan for that iirc
[14:43:17] gigem: Really? I downloaded the SDK a while back to see if it included vdpau, but all I saw was openmax. I didn't look for vulcan, though.
[14:44:46] stuarta: https://developer.nvidia.com/develop4shield
[14:45:15] stuarta: also the various opengl*
[14:47:34] gigem: Ah, that is with Android. I think the SDK I downloaded was for going the native, Linux route. Thanks for the link.
[14:47:51] stuarta: see i thought the shield ran android
[14:49:38] gigem: It does, but I saw some instructions on how to dual boot it so you can choose Android or Linux. The latter gives you an ARM system with much more powerful graphics than just about any other SOC.
[14:50:14] stuarta: tbh, i'd love to see us port natively to android on the shielf
[14:50:17] stuarta: *shield
[14:50:37] stuarta: android stuff has been worked on by markspieth
[14:51:44] gigem: I agree. That the much better and more flexible choice. I don't remember offhand who's working on an Android port, but when I checked, it still looked pretty embryonic.
[14:51:55] stuarta: ^^^
[14:52:08] gigem: Okay. I thought markspieth, but wasn't sure enough to say it.
