Can't set time values by GPMFWriteStreamStoreStamped() when using more than 2 sensors

[p51lee]

Hi, I'm trying to make a gpmf mp4 file using pre-existing sensor data (e.g. GPS, Accelerometer, Gyroscope).
By using for loops for each sensors, I succeeded in putting the streams of three sensors in one file, but the rest of the streams except the first stream did not contain the time(cts) value I put in the GPMFWriteStreamStoreStamped(...,tick) function. Actually, there were cts data such as 4004, 5005, 6006.
Is there any way to solve this problem?
