Method SetPlaybackDataset

SetPlaybackDataset(string)

Sets an MP4 dataset file to playback instead of live camera feed.

Declaration

public ArStatus SetPlaybackDataset(string path)

Parameters

Type	Name	Description
string	path	A file path to a MP4 dataset file or null to use the live camera feed.

Returns

Type	Description
ArStatus	Returns Success if successful. Returns ErrorSessionNotPaused if called when session is not paused. Returns ErrorSessionUnsupported if playback is incompatible with selected features. Returns ErrorPlaybackFailed if an error occurred with the MP4 dataset file such as not being able to open the file or the file is unable to be decoded.

Remarks

Restrictions:

• Can only be called while the session is paused. Playback of the MP4 dataset file starts once the session is resumed.
• The MP4 dataset file must use the same camera facing direction as is configured in the session.

When an MP4 dataset file is set:

• All existing trackables (i.e., anchors and trackables) immediately enter tracking state TrackingState.None.
• The desired focus mode is ignored, and does not affect the previously recorded camera images.
• The current camera configuration is immediately set to the default for the device the MP4 dataset file was recorded on.
• Calls to retrieve the supported camera configurations return camera configs supported by the device the MP4 dataset file was recorded on.
• Setting a previously obtained camera config has no effect.
