<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>I’m currently a lurker on this list, but hope to eventually include RTSP streaming in our educational presentation Mac app, iQPresenter. Latency is a major factor. We currently produce movies, create HLS variants and segments using Compressor. Talk about latency, “HLS” is a misnomer. Round trip latency could be as much as a minute with HLS. One second might be tolerable but I would hope for less. So we are definitely interested in what latency can reasonably be achieved using RTSP. <BR>

I'm using live555 as our RTSP server on a live camera, which capture and encode video into H.264 stream. Everything works fine, except that the latency is a bit high. I tried different players, including VLC, ffplay, mplayer. The lowest latency is when I set -nocache to mplayer, but still it's over 1 second. <BR>
<BR>
How should I lower the latency? Any suggestion would be appreciated.<BR>
<BR>
Btw, my camera's dim is 2048x1520, frame rate is 25fps, bit rate is 8Mbps, encoder is H.264 without B-frame.<BR>
<BR>
Thanks,<BR>
