Traffic Cameras of ".m3u8" file type - Anyone embedded?
I would like to display the South Carolina DOT traffic Camera live video feed - preferably in the MapTip dialog or Short Description.
I have camera locations and the urls for the streaming videos but am running into walls using the videos. Especially on the desktop.
Sample urls to try:
rtmpurl: (http://rtmp://8.15.251.56:1935/rtplive/40033) rtmp://8.15.251.56:1935/rtplive/40033
httpurl: http://8.15.251.56:1935/rtplive/40033/playlist.m3u8
The above file type I cannot get to play on desktop with anything (even outside GE/HTML 2.6.1). I CAN get the httpurl to open a new tab using a "link" within the short description but it only works on iPADS and some Android tablets. I cannot get it to play within the map tip or results panel.
Has anyone had any luck with this file type?

Hi Carmen! The protocol for streaming media via .m3u8 is HTTP Live Streaming, or HLS. It looks like browser support for it is pretty hit-and-miss outside of iOS/OS X, Windows 12 using Microsoft Edge, and Chrome on Android (so: Android 4.0 and higher): https://en.wikipedia.org/wiki/HTTP_Live_Streaming#Clients
On my Windows 8 machine, I can play your sample URL in Chrome or IE via https://www.hlsplayer.net/ but not in Firefox. I can also open it in iTunes by opening a stream (CTRL + U) and entering this address: (http://itls://8.15.251.56:1935/rtplive/40033/playlist.m3u8) itls://8.15.251.56:1935/rtplive/40033/playlist.m3u8
Until this protocol is more widely supported across browsers, you may have to document a workaround for users who aren't using a compatible browser.
Hope that helps!0 -
Thank you Jordan for your reply. I was coming to a similar conclusion but you provided additional helpful information. I should eventually have access to a Wowza server/app that may solve some problems. Also, there would mostly be a limited number of devices (laptops and tablets) needing access so if we have to to the "workarounds" for some laptops at least there won't be that many.
Thanks,

Happy to help!
I did some further reading, and it appears that I was overly optimistic about desktop browsers being able to support this in future. The (https://bugzilla.mozilla.org/show_bug.cgi?id=577084) Mozilla and (https://bugs.chromium.org/p/chromium/issues/detail?id=54198) Chromium open-source projects appear to be a firm "no" in favor of Dynamic Adaptive Stream over HTTP (MPEG-DASH) and, while Edge does support HLS, (https://blogs.windows.com/msedgedev/2015/07/02/moving-to-html5-premium-media/) Microsoft is also recommending DASH . Apple, who was the major driver behind HLS, (https://developer.apple.com/app-store/review/guidelines/#software-requirements) continues to require that any app that streams video longer than 10 minutes must use HLS , so it's not clear if or when they'll get behind DASH as well.
Of course, this doesn't help you unless you have some say in how SC DOT hosts their media. I guess if there's a take-away from this, it's that it may be some time before everyone agrees on a streaming video standard. Which, sadly, seems pretty standard.
...y'know, for standards.0
