I have a video website on Mac Os X. I can watch these videos on my iPhone through Http Live Streaming with wifi.I have divided the source video into 10 seconds of media per file. When I watched the video using one iPhone, there's no buffering tip.However, using three more iPhones to watch the video at the same time, it always show buffering tip. I think I have someting wrong with my website or Apache's configuration, but I don't konw how to configure. Who can tell me better ways to work seamlessly.
