Expected Behavior

When OBS_USE_EGL=1 used, XSHM appear in list of sources, XComposite doesn't apper.

Current Behavior

XSHM and doesn't apper in sources list, but works fine in EGL under X11 with little patch. Xcomposite don't work and should not work, so this patch only for XSHM.

linux-capture.c

if (obs_get_nix_platform() == OBS_NIX_PLATFORM_X11_GLX || obs_get_nix_platform() == OBS_NIX_PLATFORM_X11_EGL) {
	obs_register_source(&xshm_input);
}

Steps to Reproduce

1. Open OBS Studio with OBS_USE_EGL=1 parameter
2. Don't notice any XSHM appearance
3. Make little patch to linux-capture.c file
4. Recompile
5. Now XSHM works fine under EGL
