Troubleshooting Server Data Faults

Symptom

When data on the engine server is damaged before or after encoding, the engine reports a data processing failure event (VMI_VIDEO_ENGINE_ENCODE_ERR) on the server. You can view related messages in logs.

Impact on the System

When this fault occurs, the engine server reports the VMI_VIDEO_ENGINE_ENCODE_ERR event. Then the engine server continues encoding and sends data to the client. When the client decodes damaged frames, frame loss or temporary artifacts occur (if the damaged frames are I frames).

Possible Causes

1. The data that the engine server sends to the encoding engine after capturing images is damaged.
2. An encoding error occurs on the encoder.

Procedure

1. In the logs generated by the engine, search for logs whose LOG_TAG is VMI_VideoEngine and level is error, and then determine the cause based on the logs.
2. If frame loss or artifacts occur on the client for a short time and then recovers, you can continue with the service. If frame loss or artifacts occur for a long time, the capture engine or encoding engine on the server is abnormal. In this case, disconnect the client from the cloud phone, reconnect the client to the cloud phone, and then check whether the encoder is normal.
3. If the fault is caused by an exception of the capture engine, use the mobile phone (access end) to reconnect to the cloud phone. Then the service is recovered. If the encoder is abnormal, rectify the fault, restart the encoder, and use the mobile phone (access end) to reconnect to the cloud phone. Then the service is recovered.
