Hi there,<br><br>A few questions about this topic:<br><br>- You are streaming unicast flows, aren't you?<br>- Have you check that all packets (#seq. numbers) are both sent and received in the wireless environment?<br>- Have you tried applying different codecs and/or using different players such as VLC or gst-launch itself to check it is not a player issue?<br> - How your wireless environment is set? Mode (a/b/g/n/(+e)), QoS mapping, beacon interval, channel uniqueness, adaptive bit rate selectio?<br><br><br>Regards,<br>Javi<br><br><div class="gmail_quote">2009/5/28 Zhiqiang Liu <span dir="ltr"><<a href="mailto:liuzq2002@126.com">liuzq2002@126.com</a>></span><br> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div><br>Hi ScreenName01,</div> <div> </div> <div>Thanks for your help:-) </div> <div> </div> <div>The "ideal environment" refer to transport the udp packets in the wire communication. In this case, The possiblity of losing the packets is very small.</div> <div></div> <p>There seems to be no encryption problem since we can send the raw mpeg streams over the air to the target and play on it. </p> <p>It's really an unusual problem since we know that the the underlying medium is hidden to the protocol. The only possibly problem can occur in the MAC layer. The WLAN may lose some packets (About 10% packets are lost). But in the wire communication almost very packets are delivered normally. The problem may be related to the ts stream format. That's because it may be hard to play an ts stream when some packets are lost.</p> <p>Thanks for your suggestion. I will try to analyse the traffic using wireshark.</p> <p>I would like to keep in touch with you. When we get any progress, I will contact you.</p> <p> </p> <p>Best regards,</p> <p>Zhiqiang Liu</p><pre>ScreenName01 wrote: >Hi Zhiqiang, > > I'm unclear of what the problem is.
