Hi,<br> Thanks, Araceli.<br> I have installed 0.8.5 vlc and it works fine for playing H.264 RTP streams.<br>But unfortunately, I find 0.8.5 vlc can't play H.264 bitstream file and other files such as avi file, but
0.8.6 can do this. I'm afraid that we<br>should report a bug. <br> Do you have any vlc that can do these things at the same time? Can you share it with me?<br>thanks<br><br>Jogging<br><br><div><span class="gmail_quote">

<p>Hello,</p>
<p> I have the same problem with the 0.8.6 version. But using the 0.8.5 and adding to the code the changeset 15736, I can stream h264. And using as client the 0.8.6 I get the message "waiting for SPS.</p>
<p>Please let me know if you find the way.</p>
<p>Good luck</p>
