In grabbing mode the surface should only be locked while writing the data into the back buffer (front buffer should not be locked). Otherwise a flip on the surface would hang until the video is stopped. In DMA mode the surface should not be locked but only have the lock counter increased. -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" Convergence GmbH -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-dev" as subject.
