Disable hardware overlays on Android

[Annie]

Hi,

Is it possible to disable hardware overlays on Android so that it
reverts back to being done in software ?

Thanks
Annie

Hi,

I'm not sure if this is what you need.
You can disable h/w acceleration by setting the system property
debug.sf.hw to 0.

125 // debug: disable h/w rendering
126 char property[PROPERTY_VALUE_MAX];
127 if (property_get("debug.sf.hw", property, NULL) > 0) {
128 if (atoi(property) == 0) {
129 LOGW("H/W composition disabled");
130 attribs[2] = EGL_CONFIG_CAVEAT;
131 attribs[3] = EGL_SLOW_CONFIG;
132 }
133 }
