How To Convert .WRF Files To .WMV, AVI, MP4, XVID, or MPEG

Someone sent me a WebEx webcast they wanted me to view this afternoon. The file had a .WRF file ending which stands for WebEx Recording Format which is one of the two file formats that WebEx webcasts are saved as. The other format that WebEx files are saved as is the ARF or WebEx Advanced Recording Format. Typically you could simply download the WebEx Player available by clicking here however you may want to convert this video, which requires the WebEx Recording Editor, to provide to others in a format they can view without having to install an application. It took me awhile to figure out how to convert this file properly since I only seemed to be able to find the older WebEx Editor versions. I finally signed up for a trial account and was able to download version 3 of the WebEx Recording Editor which allowed me to convert to WMV format and from that I was able to convert to any other video format including AVI, MP4, XVID, and MPEG. Follow the directions below to first convert the .WRF to .WMV and then the second set of directions if you want to convert to another video format.

WordPress NextGen Gallery – Add Date Print Out to Compact Album Listings

I was working on my personal blog and wanted to add the date or a date range to the top of each gallery when they are listed out. The blog I am speaking of uses WordPress, WP version 2.7, with the NextGen Gallery plugin, NGG version 1.2.1, for pictures. I list the all of the galleries by using the album compact function so the below howto relates to that function only. What it will do is simply print out anything in the description field right above the image you have highlighted for each gallery. Since I was not using the description for anything else I just add the date or a date range into that field such as 01-01-2009 or 04-16-2009 to 08-10-2009.  Follow the directions below and you can print out anything you like above each gallery listing.

The NextGen Gallery shortcode used to display the galleries:

php

  1. [album=3,compact]

How to Upload Files to a WordPress Post

After WordPress 2.5 uploading files to posts has become much easier. When first looking into this I was confused though because I every time I would upload a file it would not automatically link to the file. I was assuming the file did not upload properly and that was the reason there was no file to link to. I was mistaken though and really uploading a file is exactly like uploading an image but you have to select where the file links to. Follow the simple directions below to upload files to a WordPress post on your WP blog. The directions below are based on WordPress 2.7+ however they are very similar to WordPress 2.5/2.6.

  1. Open WordPress Admin: Obviously the first thing you need to do is login to the WP administration area of your blog which is typically found at your URL followed by /wp-admin.

WordPress JPF Login/Out Plugin Logout Not Working After Upgrading to WordPress 2.7

I use the JPF Login/Out plugin to display text at the top of a WordPress site and after upgrading to WordPress 2.7 the logout link stopped working. After reading in the WordPress Codex it appears that the wp_logout_url was added to provide a nonce-protected URL that can be used during logout.

In the jpf_loginout.php file on line 17 change the below:

php

  1. $link = $before . '<a href="' . get_settings('siteurl') . '/wp-login.php?action=logout">' . $log_yes . '</a>' . $after;
