pyrealsense2.frame_queue¶

class pyrealsense2.frame_queue¶

Frame queues are the simplest cross-platform synchronization primitive provided by librealsense to help developers who are not using async APIs.

__init__(*args, **kwargs)¶

Overloaded function.

__init__(self: pyrealsense2.frame_queue) -> None
__init__(self: pyrealsense2.frame_queue, capacity: int, keep_frames: bool = False) -> None

Methods

`__init__`(args, *kwargs)	Overloaded function.
`capacity`(self)	Return the capacity of the queue.
`enqueue`(self, f)	Enqueue a new frame into the queue.
`keep_frames`(self)	Return whether or not the queue calls keep on enqueued frames.
`poll_for_frame`(self)	Poll if a new frame is available and dequeue it if it is
`size`(self)	Number of enqueued frames.
`try_wait_for_frame`(self[, timeout_ms])
`wait_for_frame`(self[, timeout_ms])	Wait until a new frame becomes available in the queue and dequeue it.

capacity(self: pyrealsense2.frame_queue) → int¶: Return the capacity of the queue.

enqueue(self: pyrealsense2.frame_queue, f: pyrealsense2.frame) → None¶: Enqueue a new frame into the queue.

keep_frames(self: pyrealsense2.frame_queue) → bool¶: Return whether or not the queue calls keep on enqueued frames.

poll_for_frame(self: pyrealsense2.frame_queue) → pyrealsense2.frame¶: Poll if a new frame is available and dequeue it if it is

try_wait_for_frame(self: pyrealsense2.frame_queue, timeout_ms: int = 5000) → Tuple[bool, pyrealsense2.frame]¶

wait_for_frame(self: pyrealsense2.frame_queue, timeout_ms: int = 5000) → pyrealsense2.frame¶: Wait until a new frame becomes available in the queue and dequeue it.
