Hi, Araceli<br> I have written a program that send H.264 RTP packet stream to a IP/Ports. Vlc on a pc with the IP as a client reads a SDP file first and then receive h.264 RTP stream from the port where H.264 RTP packets been sent to.
<br>Then I find:<br>vlc 0.8.5 can work well But vlc 0.8.6 stops after printing <br><span class="q">packetizer_h264 debug: found NAL_SPS<br>packetizer_h264 debug: found NAL_PPS
.<br><br>Further, I find vlc 0.8.5 can't play vidoe files, such avi files and H.264 AnnexB file with extension file name *.264, but vlc 0.8.6 is fine.<br><br>Best Regards<br>Jogging<br></span><br><div><span class="gmail_quote">

<p>Hi Jogging,</p>
<p>You´re welcome.<br> I think that I didn´t understand the mail correctly. You mean that you can use vlc 0.8.5 as client and server to stream h264, but you cannot use it as a player?</p>
<p>regards</p>
<p>Araceli</p>
