Convene a dual stream conference, the main meeting place use 8036 terminal, the sub stream play slides, and the main stream has two video sources, switch between the meeting place picture and the film picture. There are 26 meeting place join into the conference.
After playing 5 minutes advertisement film, switches into meeting place picture, found some meeting place pictures turned into blue screen of death. But the others meeting places can see the main meeting place picture.
Disconnect the meeting, and re-convene meeting appear the same problem, but the meeting places that appear blue screen of death are variable.
Because the cause analysis says it is media stream transmission problem, so need to rebuild streaming media connection:
First time appear blue screen of death, inform the other end to reset terminal, then it is normal.
Second time, disconnect the other end, then call it again, it will be OK.
1. The other end sent blue screen, but there is no person operate termination and have no subtitles prompt, unlikely.
2. The main meeting place see other ends pictures are blue screen of death, but they can see our picture, so it may occur problem when MCU send video stream to the main meeting place.
3. There may appear problem when the other ends meeting places send video stream to MCU.
During conference, because of media source switching, there appear media stream transmission problem, you can disconnect meeting then join again, rebuild connection.
