title: Why does a video player loose some of the first frames of a live RTP stream?
body: <p>I have written an RTSP server. It sends an h246/AAC stream data over RTP/UDP. The RTP send  packet interval for video is 30ms, for audio is 20 ms. Timestamps are extracted from the flv-tag (My server gets video and audio data from flv file). The video player looses the first few video frames. As a result audio is ahead of video by a few seconds. Why is this? Should i do any pause before streaming on server side?</p>
