问题 I'm playing video on Android using media player via RTSP. The player takes about 12s to buffer before it starts playing. Anyone know how I can convince the player to buffer less? I have full control over the RTSP server and the SDP it returns. 回答1: As per usual, as soon as I decide I should ask a question I work out the answer. I have a line "b=AS:91" in my SDP. If I reduce the number the amount of buffering decreases - so b=AS:2 gives about 4 or 5s buffering. 来源： https://stackoverflow.com
