Thank you for your faith in our abilities. We have been live streaming for 15 years. And stream on 2 CDNs, with 15 TB monthly.
The stream is playing fine on version 7.2.0 build 4113.
We also had the support team from one of our CDNs looking into this as well (for 3 days!)
The streams played fine in iOS, desktops, Android devices. Not on Sharp - Roku TV 5316x, Software version 7.2.0 build 4143. I have received a report on another Sharp - Roku TV box with the same Software version 7.2.0 build 4143, having the same problem.
h.264, (tested both main and high), AAC, Keyframes (tested 2, 5 and 10 seconds), transcoded from Wowza Media Engine, supplied directly to the player for testing, from our CDN for production. Tested with default and optimized transcoding settings from Wowza to Roku's Stream/RAF Tester Tool. I have a 1080p Live stream ready that airs 24/7 that works on version 7.2.0 build 4113.
Broadcasting on Roku, live and VOD since 2014.
