NVIDIA EGLStream controller
wl_eglstream_controller
attach_eglstream_consumer(wl_surface: object<wl_surface>, wl_resource: object<wl_buffer>)
Argument | Type | Description |
|---|---|---|
| wl_surface | object<wl_surface> | wl_surface corresponds to the client surface associated with newly created eglstream |
| wl_resource | object<wl_buffer> | wl_resource corresponding to an EGLStream |
Creates the corresponding server side EGLStream from the given wl_buffer and attaches a consumer to it.
attach_eglstream_consumer_attribs(wl_surface: object<wl_surface>, wl_resource: object<wl_buffer>, attribs: array)
Argument | Type | Description |
|---|---|---|
| wl_surface | object<wl_surface> | wl_surface corresponds to the client surface associated with newly created eglstream |
| wl_resource | object<wl_buffer> | wl_resource corresponding to an EGLStream |
| attribs | array | Stream consumer attachment attribs List of attributes with consumer attachment data It contains key-value pairs compatible with intptr_t type. A key must be one of wl_eglstream_controller_attrib enumeration values. What a value represents is attribute-specific. |
Creates the corresponding server side EGLStream from the given wl_buffer and attaches a consumer to it using the given attributes.
Argument | Value | Description |
|---|---|---|
| dont_care | 0 | Let the Server decide present mode |
| fifo | 1 | Use a fifo present mode |
| mailbox | 2 | Use a mailbox mode |
- dont_care: Using this enum will tell the server to make its own decisions regarding present mode.
- fifo: Tells the server to use a fifo present mode. The decision to use fifo synchronous is left up to the server.
- mailbox: Tells the server to use a mailbox present mode.
attrib { present_mode, fifo_length }
Argument | Value | Description |
|---|---|---|
| present_mode | 0 | Tells the server the desired present mode |
| fifo_length | 1 | Tells the server the desired fifo length when the desired presenation_mode is fifo. |
- present_mode: Must be one of wl_eglstream_controller_present_mode. Tells the server the desired present mode that should be used.
- fifo_length: Only valid when the present_mode attrib is provided and its value is specified as fifo. Tells the server the desired fifo length to be used when the desired present_mode is fifo.
