Instance methods

wpe_buffer_get_release_fence

Get the release fence file descriptor of buffer.

wpe_buffer_get_rendering_fence

Get the rendering fence file descriptor of buffer.

wpe_buffer_get_user_data

Get user data previously set with wpe_buffer_set_user_data.

wpe_buffer_import_to_egl_image

Import buffer into a EGL image.

wpe_buffer_import_to_pixels

Import buffer into a pixels buffer. The returned data is owned by the buffer and it’s not a copy, so if you are not going to use it immediately or need to modify the data, you should make a copy.

Set the release fence file descriptor to use for the buffer. The fence will be used to wait before releasing the buffer to be destroyed or reused. The buffer takes the ownership of the file descriptor.

wpe_buffer_set_rendering_fence

Set the rendering fence file descriptor to use for the buffer. The fence will be used to wait before rendering the buffer when the display supports explicit sync, see wpe_display_use_explicit_sync(). The buffer takes the ownership of the file descriptor.

wpe_buffer_set_user_data

Set user_data to buffer. When buffer is destroyed destroy_func is called with user_data.

wpe_buffer_take_release_fence

Get the release fence file descriptor of buffer and set it to -1.

wpe_buffer_take_rendering_fence

Get the rendering fence file descriptor of buffer and set it to -1.
