Re: [clutter] problem with threads and clutter-texture from file: Failed to create COGL texture
load-async is a GObject property, and can be defined using
ClutterScript:
{
type : ClutterTexture,
load-async : true,
filename : /path/to/filename,
}
Hi, I added ' load-async : true, ' to my json entries. This works
only actors without behaviours, but I have behaviours defined in json,
e.g.:
{
id : behaviour-button-press,
type: ClutterBehaviourRotate,
center-x: 40,
angle-start : 0.0,
angle-end : 360.0,
axis: y-axis,
alpha : {
timeline : { duration : 1000, loop : false },
function : sine_wave
}
}
{
name : play,
id : button-1,
type : ClutterTexture,
load-async : true,
filename : buttons/play-button.png,
x : 5,
y : 275,
behaviours : [ behaviour-button-idle,
behaviour-button-motion,
behaviour-button-press ],
signals: [
{
name: show,
handler : stage_start_behaviour,
object : behaviour-button-idle
},
{
name: motion-event,
handler : button_mouse_behaviour,
object : behaviour-button-motion
},
{
name: button-press-event,
handler : button_mouse_behaviour,
object : behaviour-button-press
}
]
},
It is possible to load behaviours async?

2009/12/2 danny tornad...@163.com: Your demo program works normally for me. Thank you very much for this information. I tested this on another computer and it worked. So I'm using clutter and threads in right way. (Maybe there should be little bit more manual than test/interactive/test-threads.c?) Perhaps it a problem related to others such as VGA driver...

Re: [clutter] problem with threads and clutter-texture from file: Failed to create COGL texture
Hi, thanks, I got it working. In test-threads.c there was this row: clutter_threads_add_idle_full (G_PRIORITY_DEFAULT + 30, update_label_idle, update, NULL); So I though it is safe to put my clutter_* code same place. (So is this clutter_threads_add_idle_full also in clutter API or not?) Now I put my code under update_label_idle, which have clutter_actor_* calls, so this might be safe place? I have lots of code using ClutterScript and json files. I realized that my target platform is too slow to load actors when needed, but it has lots of memory. I would like to use existing code, not to rewrite them using 'load-async'. -Aapo Rantalainen -- To unsubscribe send a mail to clutter+unsubscr...@o-hand.com
[clutter] problem with threads and clutter-texture from file: Failed to create COGL texture
Hi, I'm working with actor preloader i.e. main-loop is running and
another thread loads actors. I'm not even plan to add these on stage,
just load them.
In this example application I add them to stage, because now it forms
complete application.
If in thread I make clutterRectangle, it works.
If in thread I try to make clutterTexture from image file, I got
Failed to create COGL texture.
Is this bug, or how I should make this working?
#include clutter/clutter.h
ClutterActor *stage;
void *start_preloader(int parameter) {
g_usleep( 1 * G_USEC_PER_SEC );
ClutterActor *actor;
if (parameter==2)
{
GError* error = NULL;
if (!(actor = clutter_texture_new_from_file(image.png, error))) {
fprintf(stderr, %s\n, error-message);
g_error_free(error);
}
}
else
{
actor =clutter_rectangle_new();
clutter_actor_set_size (actor, 400, 80);
clutter_actor_set_position (actor, 10, 10);
clutter_rectangle_set_border_width(CLUTTER_RECTANGLE(actor),10);
}
clutter_container_add_actor(CLUTTER_CONTAINER(stage), actor);
pthread_exit(NULL);
}
int main (int argc, char *argv[]) {
ClutterActor *actor;
clutter_init (argc, argv);
stage = clutter_stage_get_default ();
actor =clutter_rectangle_new();
clutter_actor_set_size (actor, 400, 400);
clutter_actor_set_position (actor, 40, 40);
clutter_rectangle_set_border_width(CLUTTER_RECTANGLE(actor),16);
clutter_container_add_actor(CLUTTER_CONTAINER(stage), actor);
clutter_actor_show_all(stage);
pthread_t preloader_thread;
pthread_create(preloader_thread, NULL, start_preloader, argc);
clutter_main();
return 0;
}
Usage:
copy any png image to working directory and rename it to image.png
compile: gcc `pkg-config --libs --cflags clutter-1.0` main.c
./a.out
Main loop starts, then preloader waits one second. Move mouse over
stage, so it is refreshed and then second rectangle will be visible.
./a.out BUG
Main loop starts, one second later preloader tries to open png file
and gives error: Failed to create COGL texture and actor is NULL.
This error message is coming from clutter-texture:1976
(clutter_texture_set_from_file), but I do not understand why.

[clutter] clutter_behaviour breaks gnonlinear gstreamer plugin, can anybody confirm this?
Hi, I have problem with clutter1.0.6 behaviours and
gstreamer-gnonlinear-plugin. I think I'm using gnonlinear proper way,
because it works. If I add clutter and clutter_actor it still works.
When I add clutter_behavour, application doesn't work anymore.
Application:
I'm playing two different length wav-clip starting on same time.
Expected:
Shorter ends and another continues playing.
What happens:
When shorter ends, there are silence moment (cap). Sometimes it is
short, sometimes long, and sometimes there are many caps.
If I'm using alsasink, there are no message, with pulsesink I got this:
pulse pulsesink.c:523:gst_pulsering_stream_underflow_cb:sink-actual-sink-pulse
Got underflow
(This message comes even when it works.)
And as I said application works if I disable all clutter_behaviours.
This is the reason I'm posting this to clutter list, not gstreamer
list. Any advice is welcome. (Do this happens to you? Is this
gstreamer's fault? Is this gnonlinear's fault?)
I made simples version which triggers this bug and it is easy to
reproduce, you can download it from here (1.5M):
