SDL2 support

[sergio-br2]

Hi, I ported cabrio to SDL2, it seems it's working:

https://github.com/sergiobenrocha2/cabrio/tree/SDL2

The diff: https://github.com/fredbcode/cabrio/compare/master...sergiobenrocha2:SDL2

It's based on the fred fork.

I noticed only an issue with joystick, analog axis is not working.

Steve, it could be nice if you merge stuff from fred and release 0.9 or even 1.0  :)

The joystick issue is related to this:

https://bugzilla.libsdl.org/show_bug.cgi?id=2438

It's losing SDL_JOYBUTTONDOWN events too.

So, if you Alt+Tab and come back to cabrio, joystick will work again.

For some reason, Lazy Foo's example works very well: http://lazyfoo.net/tutorials/SDL/19_gamepads_and_joysticks/index.php

Other workaround for the joystick issue: open cabrio by the desktop entry, in your system menu. It will work on the first try.

Or... wait for SDL 2.0.4.

Things fixed/new:

-- <width> and <height tags> are optional now, if you use <full-screen> tag. Cabrio use SDL_GetDesktopDisplayMode to know the right resolution;
-- added support for filter events, for now it only filters SDL_TEXTINPUT event. So you can add noisy or unusable events in event_filter(), event.c;
-- fixed SDL_PollEvent() call, it was calling once per frame. Change 'while' to 'if' in event_poll(), and you'll see some slowdown in Cabrio right after you mess with an unused input, like joystick analog axis, and try to up or down the list.

Hi Sergio, About your PPA, there is created with libsdl2.0.4 beta ?

[sergio-br2]

No, it uses SDL2 from the system/ubuntu repo, i.e.:

14.04 --> 2.0.2+dfsg1-3ubuntu1.1
14.10 --> 2.0.2+dfsg1-3ubuntu2
15.04 --> 2.0.2+dfsg1-6ubuntu2

There is this PPA: https://launchpad.net/~zoogie/+archive/ubuntu/sdl2-snapshots
Maybe it fixes the joystick issue?

Maybe, but this is not the latest version

libsdl2-image 52 weeks ago

That SDL2 PPA is broken, don't try.

I built here SDL last version (4bab88dd387e, 04/13) and same issue, it seems it's not fixed yet.

Try add this in the code:

In sdl_wrapper.c:

void sdl_focus( void ) {
    SDL_Window *windowTest = SDL_GetKeyboardFocus();
    if ( windowTest == window )
        printf("\nWindow focused!!!\n");
    else
        printf("\nWindow NOT focused.\n");
}


In include/sdl_wrapper.h:

void sdl_focus( void );


In event.c:

while( SDL_PollEvent( &sdl_event ) ) {
    sdl_focus();
    event_num = EVENT_NONE;
    [...]

So after open cabrio, you'll se "Window NOT focused." after each event, then Alt+Tab out and Alt+Tab back, or click in some window and come back to cabrio, you'll se "Window focused!!!"

It seems the window is not focused at first. I tried to get focus with SDL_RaiseWindow(), but it didn't work. Any idea to workaround it?

[sergio-br2]

Finally found an workaround for this issue: just add SDL_JOYSTICK_ALLOW_BACKGROUND_EVENTS=1 as environment variable, or call cabrio with:

SDL_JOYSTICK_ALLOW_BACKGROUND_EVENTS=1 cabrio

I'll update the .desktop file

Ok the bug is fixed on the latest version  SDL_SetHint("SDL_JOYSTICK_ALLOW_BACKGROUND_EVENTS", "1"); in event.c
I will release Livemamecab soon

Thanks Sergio

Ok I'm pushing the new iso with your changes and some fixes, here http://traceroot.c.la

Still works to do

- Fix memory leaks (at least with video)
- Make a theme by list

I have still been wanting to run cabrio on a cubie board, and it is the closest to running other than retroarch. Both are giving me a warning  "libgl error: unable to load driver : mali_drm_dri.so"
then they load but ever so slow. I am assuming that the mali drivers are not doing their hardware enhanced magic. I have a cubieboard 2 and i am working in cubieez a debian based distro. I sure would love it if this started magically working. Any and all tips would be greatly appreciated. Thanks.
