Wirecast stream distorted on Edge browser on laptops and tablets


Hello,

I'm currently wrestling with a problem that's not necessarily due to JWplayer, but hopefully someone here recognizes the problem or can point me in the right direction.

We are currently streaming our webinars using Wirecast 5 and a Premium licensed JWplayer. Our Wowza mediaserver picks up the Wirecast stream and the JWplayer in turn gets an m3u8 link. Generally, we've gotten playout to work on just about all platforms and devices.

However, recently we discovered that Windows 10 laptops and tablets (for example Surface devices) have problems showing the stream in the Microsoft Edge browser.
On these devices the video glitches in the lower part of the screen, showing all kinds of pixelization, artifacts and compression issues. For an example, see a screenshot here: http://bit.ly/2dMNwbd

So far, I think we've narrowed it down to it having something to do with the Intel HD videochip on these devices. A desktop computer or even a bigger laptop with dedicated graphics card has no issues playing the stream in Edge.

Like I said, this issue isn't JWplayer-specific, if I view the stream through a standard HTML5 video player the same thing happens. Upgrading to a Wirecast 7 trial also doesn't change the outcome.

For our encoding settings in Wirecast we use the following:

Video:
Codec: x264
Resolution: 1280x720
FPS: 25
Avg. bitrate: 1500 kbps
Quality: 3 (standard)
Profile: Baseline
Keyframe every: 50 frames
Constant bitrate: Off (seems to have no influence)
Keyframe aligned: Off (same as above)

Audio:
Channels: Stereo
Target bitrate: 128 kbps
Sample freq: 44.100 kHz

Anyone got any ideas? Any help would be much appreciated!

Hi there,

As the issue is not being caused by the player, I am not sure what could be causing it, especially if it only happens on some devices. Hopefully someone on this forum can assist you. You may also want to post your question to StackOverflow.

Thank you.

Hello,

Thanks for the reply. I've filed a support ticket with Wowza, see if we can find anything there.

In the meantime, for people who may run into this problem too: We have found at least a temporary solution by forcing the JWplayer to default to Flash. This causes Edge to switch to its in-built Flash player which renders the video fine. Not exactly my idea of 'native support'

I'll be sure to post again should I find the root cause of the issue.
