Hi there,

on our Moodle site we have a prob with our video player.

Normaly we have an old Moodle 7.1 in use with an old jwplayer.

The videos are embedded by a template in the videoeasy filter 

(HTML5 tag).

If I open a subsite in our Moodle presence with embedded videos , I 

can only see a  black rectangle, where I expect to see a generated preview of a

video (m4v - File) also referred to as poster picture. When I click on the black retangled I can

watch the video. A preview is missing.

So I updated to Moodle 7.2 which allowed me to install a new 

jwplayer from Moodle.org . But the behaviour of the video does not change.

in "lib/medialib.php" I can do some settings for the video5.

Most of all I can set a value for the preload - attribute

<span class="mediaplugin mediaplugin_html5video">

<video idtag controls="true" $size preload="none" title="$title">

    sources

    fallback

...

Values for preload can be "none", "metadata" and "auto". 

I could see no changes of the video behaviour with all values.

What we want is to let the user see a preview

of all embedded videos without loading the videos entirely in order

not to generate too much traffic. In case of many videos on a site

it may block the site, may cause drag and drop probs ..

When the site is loaded the video is in a tag with a class

"jw-state-idle". Which is what we want. If we deactivate this class

while the site is loading a preview is displayed but it also causes

the loading of the video. 

So can anyone get us started in order make some video settings,

that only generates a poster picture without loading the video ?

Do you recommend other players ?

Thanks in advance for your help!

Best,

Benedikt
