Other: Kaltura Video Package
ainatte inbal, 
Akinsaya DelamarreKaltura's Video Package for Moodle 2.x makes it easy to add the robust capabilities of Kaltura's open
source online video platform to any Moodle site. The package was developed specifically for Moodle
and integrates with other features and modules, such as resources and activities, so that users can
upload and embed media easily.
The package adds the following features for all users:
* My Media: users’ personal media gallery, for uploading, viewing, managing, and sharing media
* Create screen recordings and use them in the Kaltura activities
* Integration as an external repository with the file picker accessible from the text editor: embed your media or media you have access to, anywhere you can author text
In addition, Teachers and Admins have the following features available:
* Video Resource activity: Easily add video content to your course as a specialized resource
* Video Presentation activity: Create a synchronized view of a Document and a Video
* Video Assignment activity: Allows students to submit videos as an assignment submission
* View engagement reports for videos used on your course
Version information:
Please take note of the version of Moodle you have and the version of the plug-in you are installing. The Download page states which version of Moodle the version of the plug-in is for.
Version information example: Kaltura release 3.0.96 (RL: 2.5.1.1)
3.0.96 is the version of the plug-in that Kaltura has release. It does not correspond to any Moodle version number and it should be referenced when contacting Kaltura support.
RL: 2.5.1.1 is our internal version. The first two points (2.5) correspond to the version of Moodle that it has been tested with (Moodle 2.5.x).
Yes the filter plug-in could use some improvement. Curl requests are required for two purposes 1) to generate a session and 2) to ensure the KMC is updated to reflect the context in which the video is being used on the Moodle site.
The latter is possibly the biggest hit; however this should only occur on the first page load, afterwards the entry context information is cached. Subsequent page loads will hit the database, unless a new video was posted to the page.
What happens if you refresh the page? Do you still incur a long PGT?
I haven't measured the PGT, I just injected echo statements right after both curl_exec()'s found in the code, and noticed that at least one cURL request is made on each page load, e.g. course view, even when I refresh the page. This happens even if no videos are found on the page. Any request to an external server will pause the page generation until cURL receives a response from that server, or until the request times out; this may potentially be seconds in case the server is overloaded or inaccessible for whatever reason; and yes, the cURL request itself will increase PGT. That said, this method of session generation/extension is deemed inappropriate.

Regards,
We've implemented this plugin for our Moodle implementation, we can upload any video to My Media and Share it with the site, but when we try to post this video through Moodle Media, Select File or Video we receive the following error when trying to navigate through Kaltura repository:
ERROR: Invalid JSON string.
Fatal Error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 71 bytes) in /usr/local/moodle/moodle_uem/repository/kaltura/locallib.php on line 748.
We've tried the plugin in available Development Moodle Environments and it works fine.
Is this an issue with a Moodle setting??
Any suggestions are valuable, we've ran out of possible solutions and need to solve issue ASAP.
Regards.
First try to upload a file size that is smaller than 200MB. Or even better smaller than 50MB and confirm whether you are still receiving the fatal error.
Also if you are running your development Moodle env on a different server, then there may be a difference in PHP memory limit.
Or if you are running both dev and production on the same server, there may be some other process that is eating up memory.
Which version of the plug-in are you using and list your steps one by one to reproduce the problem.
Thanks
We are using the Kaltura plugin in a Moodle 2.2.4+ environment for a customer of ours with about 40.000 users of which a fair number uses an iPad to watch the video's embedded in the Moodle courses.
We have two problems:
1. Using the latest kaltura plugin version (2012121902) for our Moodle version (2.2.4+) the video's are not displayed embedded on the page. Only a link is shown which redirects you directly to the video on the kaltura server when clicked upon.
2. Problem nr. 1 does not exist when using an older version (2012062600) of the kaltura plugin. But when we use this version the video's are not displayed properly when accessed with an iPad, which is a problem as many users use iPad's as I mentioned above. What happens exactly is: when one accesses a course with embedded kaltura video's for the first time (or with caches cleared locally on the device/iPad) the video's are displayed properly (for most courses). But when the page is refreshed/reloaded the video's are not shown at all. Nothing, not even a link, no trace of the video's at all.
Originally we where running plugin version 2012062600. Tot solve some issues we upgraded to version 2012121902. But becouse of problem nr1 I mentioned (video's not shown embedded, only a link) we went back to version 2012062600.
I hope somebody is familliar with any of these two problems. Any help is much appreciated. Especially the recent courses use a lot of video content. As this is a critical environment with a large number of users trying to access the video's every day we hope to find a solotion soon.
Thanks in advance,
Ron
