Remote video is returned by the MCU, because video images are damaged when being decompressed by the codec. Therefore, remote video has a lower quality than local video.
The possible causes and solutions.
Cause 1: A loopback test is being performed.
Solution: Check the local and remote loopback status and disconnect all local and remote loopback tests.
Cause 2: Check call statistics. If the video bandwidth is 0, no video is sent from the remote site.
Solution: Contact the administrator of the remote site to solve this problem.
Cause 3: If the remote video is displayed as a blue screen, the remote site hides its video by sending a blue screen.
Solution: Contact the administrator of the remote site to solve this problem.
Cause 4: The current video output interface is set to display the local video.
Solution: Set the current video output interface to display the remote video.
The possible cause is that the temporary view information file for storing video wall operations is damaged. The solution is as follows:
Step 1 Log in to the C/S client. Access C:\Users\OS account\AppData\Roaming\IVS\ server IP address\IVS_IVS account\.
Step 2 Delete the ScenarioFavorite.xml file in the directory.
Step 3 Exit the C/S client and log in again.
Step 4 Check whether the fault is rectified.
If the fault is rectified, no further action is required. If the fault persists, contact Huawei technical support engineers.
