Failed to initialize axoverlay: GDBus.Error:com.axis.Graphics2.Error.Unauthorized: Unauthorized Access

[rywager]

I am on a AXIS P3268-LVE Dome Camera running Current version: 11.9.60

I am using pretty much exactly the examples i see everywhere and i get the error in subject line whenever i start up.

Anyone have insight as to what "Failed to initialize axoverlay: GDBus.Error:com.axis.Graphics2.Error.Unauthorized: Unauthorized Access" means?

`static void
render_overlay_cb(gpointer render_context, gint id,
struct axoverlay_stream_data *stream,
enum axoverlay_position_type postype, gfloat overlay_x,
gfloat overlay_y, gint overlay_width, gint overlay_height,
gpointer user_data)
{

GError *error = NULL;
// Get maximum camera resolution
gint camera_width = axoverlay_get_max_resolution_width(1, &error);
gint camera_height = axoverlay_get_max_resolution_height(1, &error);
if (error) {
    syslog(LOG_ERR, "Failed to get camera resolution: %s", error->message);
    g_error_free(error);
    return 1;
}

static gdouble pie_angle = 0.0;

cairo_t *cr = render_context;
gdouble x = camera_width/2;
gdouble y = camera_height/2;
gdouble radius = PIE_RADIUS;
gdouble angle1 = 0;
gdouble angle2 = pie_angle*(M_PI/180.0);

/* Clear background */
cairo_set_source_rgba(cr, 0.0, 0.0, 0.0, 0.0);
cairo_set_operator(cr, CAIRO_OPERATOR_SOURCE);
cairo_rectangle(cr, 0, 0, camera_width, camera_height);
cairo_fill(cr);

/* Draw a filled pie shape */
cairo_set_source_rgba(cr, 1.0, 0.0, 0.0, 1.0);
cairo_set_operator(cr, CAIRO_OPERATOR_SOURCE);
cairo_set_line_width(cr, 5.0);
cairo_arc(cr, x, y, radius, angle1, angle2);
cairo_line_to(cr, x, y);
cairo_line_to(cr, x+PIE_RADIUS, y);
cairo_fill(cr);

}

int main() {

GError *error = NULL;

axoverlay_reload_streams(&error);
if (error) {
    syslog(LOG_ERR, "Failed to reload streams: %s", error->message);
    g_error_free(error);
    return 1;
}

if (!axoverlay_is_backend_supported(AXOVERLAY_CAIRO_IMAGE_BACKEND)) {
    syslog(LOG_ERR, "AXOVERLAY_CAIRO_IMAGE_BACKEND is not supported");
    return 1;
} else {
    syslog(LOG_INFO, "AXOVERLAY_CAIRO_IMAGE_BACKEND is supported");
}

syslog(LOG_INFO, "Starting up...");
/* Initialize the library */
struct axoverlay_settings settings;
axoverlay_init_axoverlay_settings(&settings);
settings.render_callback = render_overlay_cb;
settings.adjustment_callback = NULL;
settings.select_callback = NULL;
settings.backend = AXOVERLAY_CAIRO_IMAGE_BACKEND;
axoverlay_init(&settings, &error);
if (error != NULL) {
    syslog(LOG_INFO,"Failed to initialize axoverlay: %s", error->message);
    g_error_free(error);
    return 1;
}`

U forget Manifest entry for dbus Ressource right?

[pataxis]

Yes, as @Cacsjep says, to use axoverlay you need to add the the D-Bus resources to the manifest.json when using a dynamic user.

That absolutely did it, thank you as always @Cacsjep !
