ffmpeg开发rtsp live server，欢迎有经验的朋友进来.

最近被这个问题搞疯了。
自己写的一个RTSP小实现:实现RTP传输H.263实时载荷.
，在公司的电脑(double core/1GM)上表现不错，可以对多个连接提供不错的稳定的码流，一般几个小时都没问题,在家里的电脑(性能比公司的茶很多)上一般只能播放16秒钟,VLC, Real player就会断掉session，然后重新发起session:
现在VLC调试信息显示如下：

为了问题，痛苦不堪，我初步估计是pts的问题，这个时间戳，我想了很多办法
我现在是纪录采帧时候的每帧的tick数(11/1000秒)，然后换算成90KHZ的时钟tick(1/90000),请问一下，我这个有什么问题吗？
Real player得信息显示:所有的frame全部dropped掉了
FramesDropped = ***
CurrentFramerate = 0
DisplayFrames = 0
郁闷死了

不懂，帮顶

[Oversense]

不是pts的问题，是其它问题

不过就这点信息也不知道那儿的问题。方便可以看下exe

[benztoy]

楼上留下QQ或MSN吧，请教一下

情况终于有所改善，我在rtp的采样timestamp的基础上，加上一个摆幅为增量1/2的随机抖动。
基本上正常了，但是导致大量的late picture skipped,丢帧10%，不知道解决问题的关键在那里。 我测试了Mplayer完全正常,VLC,Real Player还有这个问题

[benztoy]

终于OK了,丢帧律在1%以内

最讨厌解决了问题不把方案写出来的，看国外的论坛解决方案都详细的很。
