Video Transcoding shows CPU consumption error

Hello experts,
This video transcoding gives me this error and it says that it consumes all CPU time. I have an Intel i3 CPU with 3.2GHz and I don’t think this program requires a better CPU. Please can anyone help me to fix this error? Why it says that is a problem with my CPU? Thanks !

The encode thread seems to be blocked. If you are not running other program that consumes all CPU time, this may indicate that the encoder has encountered an error and stopped working. Do you want to interrupt the task?
