Hi,<div><br class="webkit-block-placeholder"></div><div>The encoder configuration of your H.264 file is also important besides those two live555 parameters. If you are using hierarchical B-pictures, FFMPEG and therefore VLC do not support them correctly. In my experience GOP up to 8 frames works OK, but larger GOP values with hierarchical B-pictures can create visible decoding artifacts in FFMPEG/VLC, even if you set those parameters correctly.</div><div><br class="webkit-block-placeholder"></div><div>Cheers,</div><div>Engin.</div><div><br><div><div>On 20.10.2007, at 03:50, Raymond Tam wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"> <div class="Section1"><p class="MsoNormal"><font size="2" face="Arial"><span style="font-size:10.0pt; font-family:Arial">Hi,<o:p></o:p></span></font></p><p class="MsoNormal"><font size="2" face="Arial"><span style="font-size:10.0pt; font-family:Arial"><o:p> </o:p></span></font></p><p class="MsoNormal"><font size="2" face="Arial"><span style="font-size:10.0pt; font-family:Arial">I’ve implemented my H.264 framer but my streaming video doesn’t look right on the VLC client, it looks jittery and the picture breaks up. <o:p></o:p></span></font></p><p class="MsoNormal"><font size="2" face="Arial"><span style="font-size:10.0pt; font-family:Arial"><o:p> </o:p></span></font></p><p class="MsoNormal"><font size="2" face="Arial"><span style="font-size:10.0pt; font-family:Arial">From reading the past mailing-list archive, I get the idea that in my h.264 framer I have to only set “fPresentationTime” and “fDurationInMicroseconds” properly, and then the H264VideoRTPSink will take care of setting the RTP timestamp correctly.
