Why does it prompt that the video is being transcoded after uploading?

Video added to the material library needs to be transcoded. Only after the transcoding is successful can it be uploaded into the service package. The transcoding time varies depending on the length of the video content. If you are unsuccessful for a long time, you can contact management. Warm reminder: The original video file name must be in Chinese and cannot contain characters, etc. The video length should not exceed 1 hour, otherwise the transcoding will not be successful.
