At the beginning of playing the network stream with GStreamer, a black screen will occasionally appear for about 6 seconds
I use GStreamer to play RTP video stream. I first set the playing pipeline to the playing state, and then open the streaming server. The video will occasionally appear black screen (without any picture), which will last for about 6 seconds, and then a normal picture will appear.
Then I used the VLC player to test the video stream. When there is a black screen for 6 seconds, there will be the following error message.
I think it may not be the problem with my GStreamer pipeline, but the problem with video streaming. But I don't know what's wrong with the video stream, or what tests I should do.
