RE: Should I always add wl_display_sync() before wl_display_dispatch_queue()?

Then application is blocked. So, I still think the padding wl_display_sync is required.

Should I always add wl_display_sync() before wl_display_dispatch_queue()?

Video player use frame callback on an event queue, sometimes there is synchronization issue. After looked at other usage of event queue, I found: In order to avoid blocking by wl_display_dispatch_queue(), a padding callback of wl_display_sync is added on purpose. Is my understanding correct? Here

erver in webkit. Seems mesa requires wayland server send wl_buffer_send_release upon attach. From: wayland-devel-bounces+halley.zhao=intel@lists.freedesktop.org [mailto:wayland-devel-bounces+halley.zhao=intel@lists.freedesktop.org] On Behalf Of Zhao, Halley Sent: Monday, September 02, 2

how to deal with the last video frame buffer (wl_buffer)?

When a wl_buffer (of video frame) is committed to wayland server, this buffer keeps being used by server until a second buffer is committed. It means a wl_buffer isn't ready to destroy in frame callback, but wl_buffer_send_release(). And the buffer (in media pipeline) should also be retained for

Fail to bind wayland interface after a shell surface is created

Some debugs show, after a shell surface is created, the future registry_handle_global (of wl_registry_listener) doesn't receive any interface. There are some wl_registry_listener in the stack, if I skip wl_shell_get_shell_surface from the previous bind, it will be ok. It seems: after one shell s
