I cannot build it in ubuntu 20. I use the docker install. However, I find the rtsp can published successfully, the brower client cannot subcribe it. when I try to use it open mkv files.

[fengmao31]

I think there are some requests on the rtsp streams and based on vp8.

[fengmao31]

where you get the information, I cannot get the print in the docker terminal. maybe I can compare our debug infromation.
