Problem description

Cameras were not displaying live view on IVS Client and video wall, showing an error code 999115450.

Problem analysis

1. Confirmed the VCN540 version.
   

2. Checked the error code 999115450, which stands for IVS_PLAYER_RET_RTSP_ERR_TIMEOUT.
   

3. Collected and analyzed the MU log and found that there were two threads locked.
   

Root cause

There are two threads waiting for the send stream thread exit semaphore. But there is only one semaphore released, so one thread was freezing until the MU service restart.
