Vimeo videos don't play using the Widget Connector macro

Summary

Vimeo videos that are added with the Widget Connector macro do not play on any version of Confluence or in any platform or browser.

Steps to Reproduce

1. Create a page, add the Widget Connector Macro and insert a embed link to a Vimeo video.
2. Save and update or publish the page

Expected Results

The video should be embedded and display a thumbnail and the controls for the video.

Actual Results

The screen remains blank.

Notes

Looking at the browser console it's clear that the embed method used in the connector no longer works as the (https://vimeo.com/moogaloop.swf) file returns a 404.

Workaround

For Confluence 6.6+, install Widget Connector 3.1.2: widgetconnector-3.1.2.jar. This will not work in Confluence 6.5 and lower.

For Confluence 6.5 and lower:

There is no workaround in the macro itself, however a user macro can be created instead as an alternative using the below code which will use the iframe embed method instead.

## Vimeo video macro
## @param URL:title=Video URL|type=string|required=true|desc=Enter the full Vimeo URL (e.g. https://player.vimeo.com/video/223136582 )
## @param Width:title=Width|type=int|required=true|default=640|desc=Player width in pixels (e.g. 640)
## @param Height:title=Height|type=int|required=true|default=360|desc=Player height in pixels (e.g. 360)

<iframe src="$paramURL" width="$paramWidth" height="$paramHeight" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
