VIDEO PLAYER 3.x questions:
"I am getting the following error message when I logged in"
- This erorr means that mp4 video format is not added/allowed in your IIS (Internet Information Service) directly for your website. You will need to add .mp4 as a MIME type in IIS.
The article about adding .mp4 MIME type in IIS
Can I get the Video Player version 3 for free if I purchased version 2 before?
- Upgrade from version 2 to version 3 of the module is paid.
I am unable to select file in Video Player. Please advise.
- Please, check whether your video file formats are added into the Allowable File Extensions (Host -> Host Settings page). Then you should synchronize files and folders in the Admin -> File Manager.
After all these steps I think you will see your video files in the settings of Video Player.
Please, note the Video Player 3.x doesn't support flv, it supports only mp4 and movies from YouTube and Vimeo. Other video formats and stream video websites haven't been listed in the feature list. Anyway it might work well.
What kind of links should I put into your module settings to play the video from YouTube/Vimeo?
You should use the embed code to play videos from YouTube/Vimeo.
The link from 
should have the following format:
<iframe width="560" height="315" src="http://www.youtube.com/embed/RFOsppI-QfQ" frameborder="0" allowfullscreen></iframe>
from 
(new embed code):
<iframe src="http://player.vimeo.com/video/8079335?title=0&byline=0&portrait=0" width="400" height="250" frameborder="0" webkitAllowFullScreen allowFullScreen></iframe><p><a href="http://vimeo.com/8079335">Menu Factory - an online DotNetNuke menu customization service</a> from <a href="http://vimeo.com/codingstaff">Coding Staff</a> on <a href="http://vimeo.com">Vimeo</a>.</p>
Tuning Advice:
Our module is developed so that the more video formats you indicated in the module settings (webm, mp4 and flv - the best variant), the faster player works in different browsers.
VIDEO PLAYER 2.x questions:
"I can't see my video files in the dropdown in dnn video player module settings even though I've uploaded them to selected folder"
- Make sure you can see the files in Admin->File Manager. In case you can't, you need to Synchronize files in the folder where you uploaded your video.
"I am getting error when I am uploading .flv video to the server using standard DotNetNuke File Manager"
- Make sure you've added .flv, .mp4 and .mpeg4 as allowed files extensions in Host Settings->Other Settings
"My video is not being played even though I can see it in File Manager"
- Make sure that .flv, mp4 or mpeg4 are allowed MIME types in your IIS configuration. Try to access your files via http protocol using direct url, e.g. http://yourdomain.dom/Portals/0/fileName.flv. In case you are getting 404 error or server drops a connection, please contact your hosting provider asking to add .flv, mp4 and mpeg4 as allowed MIME types. Check this article on more information about adding MIME types.
"When the CS video player module is added, the module shows up to 600x800, and is in front of the module option drop down where the settings are. I have to minimize the module to get at the settings. (I'm using current Firefox on an xp box)"
- Location of the module settings dropdown depends on your dnn module container. You need to work container.css file of the selected container in order to place module settings links on the right spot.
"If a video is not played in you video player and you see buffering and loading going on for a long time."
- You should check whether appropriate MIME types are added to IIS. If you are operating on the basis of Windows 2003 Server but looking for a change in your usual download streaming employing Flash (.FLV), MPEG-4 and H.264 (.mp4) formats, it is necessary for you to add several MIME types to your server before you actually get down to streaming your content. Here you will find a quick tutorial on how to do it.
"I have uploaded MP4 video and try to play in. I can hear the sound but I can't see the video"
- More likely your MP4 video doesn't have properly formatted META information. Try using another video converter or convert this video to FLV.
"DNN video player displays 0:00 as my MP4 video length and shows play button above the video"
- More likely your MP4 video doesn't have properly formatted META information. Try using another video converter or convert this video to FLV.
"Video Player disappears when I hover menu in Safari"
- More likely you are using Sol Part menu or some other custom menu component that throws javascript errors in safari and brakes scripts execution. Only solution in this case is to replace site navigation with a bug-free menu module. Our Menu Box is exactly what you need then.
"I try putting in a size in the fields for width and height in the module settings (default being 800x600), but it does not resize, and when i go back into the settings it is back to the default. It seems I cannot have any other size other than 800x600."
- Seems that the problem in generating thumbnails for a video file. Please, try to uncheck "Generate Thumbnail Automatically" (in the settings), choose thumbnail image, choose necessary size of player and hit "Update". I think it will solve your problem.
