ReplayCameraProvider ¶

ReplayCameraProvider(
    replay_folder: Path, replay_interval: float = 0.01
)

Bases: CameraProvider[ReplayCamera]

This module collects and simulates cameras by looping over images in a drive.

NOTE: The first image of each camera will be emitted at any time before the timestamp of the second image. Therefore, setting the time to 0.0 will cause all cameras to emit their first image.

Parameters:

Name	Type	Description	Default
`replay_folder`	`Path`	path to the root replay folder containing the camera folders	required
`replay_interval`	`float`	the interval at which the provider checks for new images (in seconds)	`0.01`

create_ui ¶

create_ui(
    *,
    skip_time: float = 2.0,
    time_label_format: str = "%d.%m.%Y %H:%M:%S"
) -> None

Create a simple UI for controlling the replay.

Parameters:

Name	Type	Description	Default
`skip_time`	`float`	the amount of time to skip when pressing the skip buttons (in seconds)	`2.0`
`time_label_format`	`str`	the format to be used for the current time label (used by `datetime.strftime`)	`'%d.%m.%Y %H:%M:%S'`

jump_to ¶

jump_to(percent: float) -> None

Jump to a specific point in the replay.

Parameters:

Name	Type	Description	Default
`percent`	`float`	a value between 0.0 and 100.0, where 0.0 is the start and 100.0 is the end	required

jump_to_time ¶

jump_to_time(time: float) -> None

Jump to a specific time in the replay.

Parameters:

Name	Type	Description	Default
`time`	`float`	time in seconds	required

set_speed ¶
