[Android] Why i cant use all options for 3d stereoscopic shader?

[MarceloMachadoxD]

At Xiaomi Redmi Note 7 why I just can use the 3d shuttering from 3 different 3d stereoscopic avaliable shaders?

Android 9
Retroarch 1.8.9
The same issue to 32 and 64 bits version
Just woking with open gl vídeo driver

Tested cores

So, are you experiencing an error when you try to load the stereoscopic (3D) shaders? I don't understand this issue very well.

Follow the screenshots

Just the shuttering shader option load

The normal side by side shader did have a missing path. Not sure why the others wouldn't load for you, they did on my iphone, but the defaults were definitely not designed for my phone. Submitted a fix for the bad path here.

#130

I think some of the parameter names were poorly decided. y_loc was good but then the other axis ended up being called "BOTH" in all caps when I was expecting x_loc... based on logic before having looked at the source.

thanks guy, i need wait until it merge to master branch to test?

I don't actually know, depends on what their upstream process is like - it has been merged on this particular repo, but I have no idea how frequently they then rebuild the beta or stable builds of RetroArch itself. It might be there and it might not.

If not you can go through the trouble of finding the install path of your shaders and create the files themselves, however you want to go about doing that.. email, adb, a messenger app.. snapdrop.net, etc.

The files with the full update were actually on #132 and was merged 11 days ago, but again no idea when RetroArch rebuilds.

If this does solve your problem though then this ticket might be as good as closed.

You will need to change your emulator's core aspect ratio to 16x9 in the settings otherwise it will possibly squash your output to 4:3. Not aware if it is possible to update the shader to reset a core's aspect ratio.

Shaders can't set the frontend's aspect ratio, no. It would be nice, though.
