I did not read the "live555 proxy server" yet. But from the name I guess this server will work as a proxy. But I am expecting to do a little different. I'd like the live555 will support the source to publish the video directly. I suppose the supporting of "RECORD" and "ANNOUNCE" in RTSP shall be added. I wander if there is any special consideration that the live555 does not support them.</span></div><div><span><br></span></div><div><span><span class="Apple-tab-span" style="white-space:pre"> </span>And for the </span><span style="font-size: 12pt; ">H264VideoStreamDiscreteFramer thing, you are right.

eliminated.</span></div><div><span><br></span></div><div><span>Regards,</span></div><div><span>Lan Zang(Sander)</span></div><div><br></div> <div style="font-size: 12pt; font-family: 'times new roman', 'new york', times, serif; "> <div style="font-size: 12pt; font-family: 'times new roman', 'new york', times, serif; "> <div dir="ltr"> <font size="2" face="Arial"> <hr size="1"> <b><span style="font-weight:bold;">From:</span></b> Ross Finlayson <finlayson@live555.com><br> <b><span style="font-weight: bold;">To:</span></b> LIVE555 Streaming Media - development & use <live-devel@ns.live555.com> <br> <b><span style="font-weight: bold;">Sent:</span></b> Saturday, April 28, 2012 5:32 PM<br> <b><span style="font-weight: bold;">Subject:</span></b> Re: [Live-devel] The question on how to handle the incoming H.264 RTP data of live555 server<br> </font> </div> <br>

Because the data source (a "H264VideoRTPSource") delivers discrete H.264 NAL units (i.e., one at a time), rather than a byte stream, you must use a "H264VideoStreamDiscreteFramer", not a "H264VideoStreamFramer".</div><div><br></div><div>Everything else looks correct, as far as I can tell.</div><br><br><div>
