Google.XR.ARCoreExtensions.ARRecordingManager

Provides access to session recording functionality.

Summary

Inheritance

Inherits from: UnityEngine::MonoBehaviour

Properties
`RecordingStatus`	`RecordingStatus` Gets the current state of the recorder.

Public functions
`RecordTrackData(Guid trackId, byte[] data)`	`RecordingResult` Writes a data sample in the specified external data track.
`StartRecording(ARCoreRecordingConfig config)`	`RecordingResult` Starts a new recording, using the provided ARCoreRecordingConfig to define the location to save the dataset and other options.
`StopRecording()`	`RecordingResult` Stops the current recording.

Properties

RecordingStatus

RecordingStatus RecordingStatus

Gets the current state of the recorder.

Details
Returns	The current RecordingStatus.

Public functions

RecordTrackData

RecordingResult RecordTrackData(
  Guid trackId,
  byte[] data
)

Writes a data sample in the specified external data track.

The external samples recorded using this API will be muxed into the recorded MP4 dataset in a corresponding additional MP4 stream.

For smooth playback of the MP4 on video players and for future compatibility of the MP4 datasets with ARCore's playback of external data tracks it is recommended that the external samples are recorded at a frequency no higher than 90kHz.

Additionally, if the external samples are recorded at a frequency lower than 1Hz, empty padding samples will be automatically recorded at approximately one second intervals to fill in the gaps.

Recording external samples introduces additional CPU and/or I/O overhead and may affect app performance.

Details

Parameters

`trackId`	The unique ID of the track being recorded to. This will be the TrackData.Id used to configure the track.
`data`	The data being recorded at current time.

Returns

RecordingResult.OK if the data was recorded successfully, or a different RecordingResult if there was an error.

StartRecording

RecordingResult StartRecording(
  ARCoreRecordingConfig config
)

Starts a new recording, using the provided ARCoreRecordingConfig to define the location to save the dataset and other options.

If a recording is already in progress this call will fail. Check RecordingStatus before making this call. When an ARCore session is paused (unless ARCoreRecordingConfig.AutoStopOnPause is enabled), recording may continue. During this time the camera feed will be recorded as a black screen, but sensor data will continue to be captured.

Session recordings may contain sensitive information. See documentation on Recording and Playback to learn which data is saved in a recording.

Details

Parameters

config

ARCoreRecordingConfig containing the path to save the dataset along with other recording options.

Returns

RecordingResult.OK if the recording is started (or will start on the next Session resume.) Or a RecordingResult if there was an error.

StopRecording

RecordingResult StopRecording()

Stops the current recording.

If there is no recording in progress, this method will return RecordingResult.OK.

Details
Returns	RecordingResult.`OK` if the recording was stopped successfully, or RecordingResult.`ErrorRecordingFailed` if there was an error.
