When my multi-media api program starts, there is a chance that the following print will appear and it will not work properly.It will have a kernel syncpoint error

I started a multi-channel encoder\decoder thread in my process, but added a thread lock when initializing the encoder/decoder device.
What is the cause of the problem and how to avoid it ?
Thanks a lot !
