glspectrum / projectm doesn't start on win32

Both visu glspectrum and projectm doesn't run on win32 because vlc_gl_surface_Create can't find a "glx" opengl module. I tried to replace "glx" with "glwin32" or "opengl", but this still doesn't work.

Logs from my app, bug they are the same with vlc :

D visualization - core:  looking for visualization module matching "projectm": 4 candidates
D window - core:  looking for vout window module matching "embed-hwnd,any": 1 candidates
D window - core:  using vout window module "drawable"
D gl - core:  looking for opengl module matching "glx": 0 candidates
D gl - core:  no opengl modules
D visualization - core:  no visualization modules matched
E audio output - core:  cannot add user visualization "projectm" (skipped)

added Status::fixed label

closed

still not fixed, there is no "opengl module" available on win32 :

looking for opengl module matching "any": 0 candidates

removed Status::fixed label

reopened

added Component::Video: Direct3D / Win32 Platform::Windows desktop labels

changed milestone to %Features paradize

We need to convert glwin32 to capa "opengl" then.

xilasz: is this 2.2.0 or 3.0.0 or both?

2.2 is worse, it crashs when trying to use glspectrum or projectm (tested with latest NB). The changes that made 3.0 unable to use them (but also prevent a crash) improve the way the visu gets an opengl surface to avoid the crash (i suppose).

Do you have a backtrace with 2.2.0?

In 2.2.0 or 3.0.0 ?

bt are from lastest 2.2 NB. 3.0 doesn't crash, it just refuse to use the visu.

OK. This is correct in 3.0.0, then.

Those visu are now disabled in 2.2.0

added Status::fixed label

changed milestone to %3.0 FF

closed

And this is implemented for 3.0 for Windows.

Milestone renamed
