related

Writes data for a custom track to file.

Parameters

recording_handle	The handle of a new recording, obtained by k4a_record_create().
track_name	The name of the custom track that the data is going to be written to.
device_timestamp_usec	The timestamp in microseconds for the custom track data. This timestamp should be in the same time domain as the device timestamp used for recording.
custom_data	The buffer of custom track data.
custom_data_size	The size of the custom track data buffer.

Returns

K4A_RESULT_SUCCEEDED is returned on success

Remarks

Custom track data must be written in increasing order of timestamp, and the file's header must already be written. When writing custom track data at the same time as captures or IMU data, the custom data should be within 1 second of the most recently written timestamp.
