I tried to encode video using open h264, and push stream to rtpengine, rtp engine will do the encryption for rtp packet. chrome will pull stream from rtpengine and can play stream.

The problem is that the stream is not as smooth as expected, i enabled the log and got the following warn logs, can anyone help explain what will make this happen? Thanks a lot.
