Hi; i tried for current trunk version
same problem continues.
i changed clutter_texture_unrealize function clutter-texture.c as given
below
i comment out this part
if (priv->local_data == NULL)
{
clutter_texture_save_to_local_data (texture);
CLUTTER_NOTE (TEXTURE, "moved pixels into system mem");
}
then every thing works fine on the given platform?
what can be the matter?
The whole function is given below
static void
clutter_texture_unrealize (ClutterActor *actor)
{
ClutterTexture *texture;
ClutterTexturePrivate *priv;
texture = CLUTTER_TEXTURE(actor);
priv = texture->priv;
if (priv->texture == COGL_INVALID_HANDLE)
return;
/* there's no need to read the pixels back when unrealizing inside
* a dispose run, and the dispose() call will release the GL
* texture data as well, so we can safely bail out now
*/
if (CLUTTER_PRIVATE_FLAGS (actor) & CLUTTER_ACTOR_IN_DESTRUCTION)
return;
CLUTTER_MARK();
if (priv->fbo_source != COGL_INVALID_HANDLE)
{
/* Free up our fbo handle and texture resources, realize will
recreate */
cogl_offscreen_unref (priv->fbo_handle);
priv->fbo_handle = COGL_INVALID_HANDLE;
texture_free_gl_resources (texture);
return;
}
if (clutter_feature_available (CLUTTER_FEATURE_TEXTURE_READ_PIXELS))
{
/* Move image data from video to main memory.
* GL/ES cant do this - it probably makes sense
* to move this kind of thing into a ClutterProxyTexture
* where this behaviour can be better controlled.
*
* Or make it controllable via a property.
*/
/*if (priv->local_data == NULL)
{
clutter_texture_save_to_local_data (texture);
CLUTTER_NOTE (TEXTURE, "moved pixels into system mem");
}*/
texture_free_gl_resources (texture);
}
CLUTTER_NOTE (TEXTURE, "Texture unrealized");
}
