Hi Jeremiah,<br>
<br>
Yes I'd seen the his.js stuff in my Google travels too. I wasn't
able to make it work or understand it, quickly. Credit to Ross's
demo site, it worked, hence my taking the time to post.<br>
<br>
Yes, m3u does look like it's heading in the direction I'm interested
in too. Feel free to ping me off list if you'd like to discuss more
and don't want to noisy up Ross's list.<br>
<br>

<p class="MsoNormal">Speculating a little here based on what you
said, it seems like you’d want scalable video, from an RTSP
camera stream, delivered to the web (and support mobile web
browsers).</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Web RTC is the “right way” to go and
believe Ross is working on something for this. Web RTC can
provide pretty low latency streams. The downside as of
writing this email is that it’s supported on all web browsers
and mobile web browsers EXCEPT Safari on iOS.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Http “LIVE” Streaming (HLS). This is
supported on everything*. IIRC, not “natively” on chrome, but
if you use a JS lib (<a moz-do-not-send="true"
href="https://github.com/video-dev/hls.js">https://github.com/video-dev/hls.js</a>)
It’ll work. The downside is latency is very high.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">You can convert the RTSP stream to HLS with
ffmpeg(.exe). Use a command like this (assuming h264
compatible source stream, vcodec copy does no transcoding).</p>
