echo show show "buffering" when playing rtsp

[yanhui666]

Hi,I have successfully used echoshow to play rtsp video, but I found some problems:

1. There is a delay during playback, about 3s, is this normal?
2. The playback is unstable. When playing for a period of time, echo show will display "Buffering", and the screen will be stuck, sometimes stuck for about 1s, sometimes stuck for about 10s, and when stuck for too long, echo show will send Teardown to disconnect the rtsp connection. Do you know where the problem is and whether it can be solved, thank you,
