What steps will reproduce the problem?
1.Audio codec is opus and video codec is h264
2.chrome receives video stream
What is the expected result?
Chrome send and receive audio and video streams normally and video can play normally.

What do you see instead?
Probability (about one percent to five percents），once chrome received video stream,the remote video is still，the tab page is also still , all the buttons have no response。Browser stops sending and receiving audio and video streams. After about one minute，the tab page crashes. If I open a new tab page,it is OK.

I test on M57，M59，M60，the problem has not appeared yet.


What version of the product are you using? On what operating system?
M58,windows7
