Can you play videos with Alfresco?

[zebra]

Hello everyone,

I discover now Alfresco and I wonder if it is possible to play streaming videos from the interface of Alfresco share.

Thank you in advance for your answers.

Yes.

You'll need to do some custom configuration. Change the default preview page to load a video player such as http://flowplayer.org/. They can then progressively download flv files from Alfresco. You can also configure ffmpeg (http://ffmpeg.org/) to convert video files to flv using http://wiki.alfresco.com/wiki/Content_Transformations.

Thanks a lot for your answer, I'll see that.

I tried to change the webpreviewer per the flowplayer but it don’t work. How do you do for custom this page. If it works, can I preview all documents .doc, .pdf, and .flv ?

Otherwise, it may be easier to put videos in the blog or wiki and customize TinyMCE.

Can you help me?

Best regards.

Modify web-preview.get.html.ftl to check the mime-type of the content to render the Alfresco Web Preview component or Flowplayer.

I did a little customization of web-preview.get.html.ftl file. I do not know if it is good practice, but it works.

Now, I try to configure ffmpeg to convert flv to wmv file.
I put the Ffmpeg folder in the Alfresco root , I added the bin folder in the path.
I created a file my-transformers-context.xml with the following script:

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

The error contains the solution: you're missing a wrapper element, "<beans>"

A 'sneaky' way to solve this in v3.2 would be inserting a webview dashlet and uploading your video elsewhere  :wink:

[zebra]

I just saw in the path "share\WEB-INF\classes\alfresco\site-webscripts\org\alfresco\components" a content-viewer folder with inside different templates (video, audio, test …). How can I activate these templates?

Best regards
