cannot use 3d_mode sidebyside in android

[josedavid]

This is an issue in the android version. I have a "poor man's" VR set similar to google cardboard. I tried to set 3d_mode to "sidebyside", but it failed with a black screen (text and HUD were rendered OK, tough). When set to "none", it works OK.

Is the bug reproducible?

Yes

How can you reproduce the bug?

Yes, every time I edit minetest.conf to include the line "3d_mode = sidebyside", or use the "Advanced settings" button to do the same.

What is your operating system?

android 5.0

What is your version of Minetest?

0.4.14.14 (latest on f-droid)

What game do you use? (e.g. minetest_game, MiniTest, dwarves)

The stock one included in the Android version, so it must be minetest_game



The error output is:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

2016-09-11 19:58:57: ERROR[Main]: Irrlicht: Your driver claims to support GL_BGRA but fails on trying to upload a texture, converting to GL_RGBA and trying again

This error comes from line 179 in build/android/patches/irrlicht-texturehack.patch (https://github.com/minetest/minetest/blob/master/build/android/patches/irrlicht-texturehack.patch#L179). Note, however, that message in line 184 (informing that textures could not be uploaded after retrying) is never shown.

I have no idea about OpenGL nor OpenGL ES. Any ideas about how to solve this?
