Player has issues with Firefox and IE 11

We setup this test page to play around with Viblast player:


http://listinform.com/vblast/playerIE.html


It works fine in Chrome but fails with Firefox and IE 11. Look at the attached screenshots. Please advise what we are doing wrong here. With IE 11 its weird, it worked on Win 7 but fails on Windows 2008 and 2012 servers.


Also advice on what CDNs to use for production use.


Thanks.


Hi Jasdeep,


We tested with IE11 and Firefox.

If you click the button "play", the player will play the stream.

You see the error messages because your video tag initially contains empty src element.

If you don't want to see these messages just remove the source tag from the page:

<video id="vplayer" class="video-box-shadow video-js" width="640" height="360" autoplay controls data-viblast-key="T4XhMVs2Fm">

<source src="" type='application/x-mpegURL' />

</video>


should become:

<video id="vplayer" class="video-box-shadow video-js" width="640" height="360" autoplay controls data-viblast-key="T4XhMVs2Fm">

</video>



Firefox is happy now but removing the source tag from the page did not fix the problem for IE 11 on Window Server 2008/2012. Also, confirm if CDN refs used on the page is good for production use. Thanks.

Hi,


Viblast Player is verified to work on IE11/win8/win10 without flash and on IE11/win7 with flash fallback via video.js framework.

We didn't test it with Windows Server XXXX. Check if the windows server you tested with has flash installed. Anyway, we don't officially support it.

Ok. Pls, confirm if CDN refs used on the page is good for production use. Thanks.

Hi,

It is not clear enough what do you mean, but if you mean the src address of the Viblast library:

<script src="https://viblast.com/player/free-version/sdqsdx86/viblast.js"></script>

You have to choose:

<script type="text/javascript" src="https://cdn.viblast.com/vb/stable/viblast.js"></script> as it is suggested by our embed code generator.

If you want to serve the library from your own cloud or data centre, you can download the latest version from here:

https://cdn.viblast.com/vb/stable/viblast-player.zip

and serve it from your own infrastructure.


Best regards,

Stefan

Thank you that helps :)

Player performs very poorly on IE 11. It takes forever to get started even on high speed internet. Please advice how to improve it. http://listinform.com/vblast/playerie.html


Even on your website, http://viblast.com/player/demo-user-stream/, it performs bad.


Hi,


Tested  with your page on IE11/Win7 Core2Duo with 8GB RAM and IE11/Win10 i3 6GB RAM - works as expected.

Can you clarify what do you mean by "very poorly" because we didn't notice any lag or performance issue.


"very poorly" means it takes a long time to load the video and then playback is not continuous, buffers a lot, where as same page on same machine performs great on Chrome and Firefox. Using Win 7 professional/4 GB RAM.

Hi,

As of v.35, the flash fallback is improved. Can you test again?

Also we saw that your stream is 640x360 with  29fps, but the bandwidth is 3-4mbit/s. You definitely have to check the encoder settings.
