As mentioned before, after we upgraded Kaltura from 11.2 to 12.10, videos can be played (when the player is displayed) but others cannot be played when the player is not displayed. Kaltura is configured to use ssl and https and our internal web server is configured to use http. People in our organization use our internal web server to get information and occasionally play videos. Since our web server uses http, the traffic between a google chrome web browser and our web server is http traffic. When someone plays a video, the web browser communicates with Kaltura using https port 443 for httpd and 8443 for nginx.
Most of our web pages do not use dynamic embed and the videos play fine using VOD, HLS-JS etc.
Now that I have provided this background information and clarification, can you please re-read my first post so you can better understand the root cause and what we did to prove that the problem seemed to be caused by code in the javescript.
To clarify further, when I login to Kaltura Admin Console from another google chrome tab, and use preview and embed to create a standalone page with a player and paste the url into another tab, I can play all the videos. The player works fine and can play all the videos. As mentioned before, if our WEB server page embeds a player statically, there are no problems and videos play using VOD and HLS-JS over Kaltura TCP ports 443 and 8443 using ssl and https. Pages that contain dynamic embed (via kwidget) do not display a player and therefore cannot play videos.
Sorry I can’t provide a url to our internal web server and Kaltura. It is not accessible to the public.
I think that you could probably reproduce the problem on your CentOS AIO CE host by changing code in /opt/kaltura/app/cache/html5/v2.53/l/oader_https.min.2.53.js
This should result in the java script sending a http request to your kaltura system which is configured for ssl and expects https rather than http requests. This is what happens on our system and as a result, the player is not displayed when kwidget dynamic embed is used.
