Video Streaming in SharePoint 2007/Media Player in SharePoint 2007

The idea came that I need to do video streaming in SharePoint 2007, I did small research and found 2 ways to do such a thing:

Method1:

1. Add Content Editor Web Part into your page.
2. Edit the properties of the web part.
3. Click the “Source Editor”
4. Simply copy and paste this code:

<\OBJECT id="VIDEO" CLASSID="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" type="application/x-oleobject">
<\PARAM NAME="URL" VALUE="http://sitename:42875/Documents/CocaCola-Jump.wmv">
<\PARAM NAME="animationatStart" VALUE="true">
<\PARAM NAME="transparentatStart" VALUE="true">
<\PARAM NAME="SendPlayStateChangeEvents" VALUE="True">
<\PARAM NAME="AutoStart" VALUE="false">
<\PARAM name="uiMode" value="mini">
<\PARAM name="AutoRewind" value="true">
<\param name=enableContextMenu value=false>
<\OBJECT>

Explanation: the idea behind this code is simply you create an object with a classid that indicates windows media player version 7. This code will create an embedded instance of windows media player and plays the video you uploaded in your document library.

Method2: Media Player Web Part

It’s a readymade media player web part that runs an instance of windows media player and plays all the type of files the player can play, and the credit for this web part goes to the owner who built it as you will see in the link.

1. Download the web part from this link: http://www.sharepointblogs.com/files/folders/ajp/entry3059.aspx
2. Copy the mediaplayerwebpart.dll to the bin folder of your MOSS web site.
3. Open the web.config of your site and add SafeControl entry like this: <\SafeControl Assembly="MediaPlayerWebPart, version=1.0.0.0, Culture=neutral, PublicKeyToken=4907dffeafb11512" Namespace="NFWebParts" TypeName="*" Safe="True" />
4. Inside your site, go to Site Actions > Site Settings > Modify All Site Settings > Gallery > Web Parts
5. Click New > select the media player web part > populate gallery
6. Now your web part is there, you can use it in any page and play videos

Hope this article was useful for all.

form submission exceeded the maximum length error message when you upload a file to your Windows SharePoint Services Web site

Problem:
I was trying to upload a file of a 50 MB size in a SharePoint document library and I got this error due to exceeding the maximum allowed file size: “Unhandled Exception: Microsoft.SharePoint.SPException: The form submission cannot be processed because it exceeded the maximum length allowed by the Web administrator. Please resubmit the form with less data”.

Cause:
This problem happened due to exceeding the maximum upload size limit.

Resolution:
You can resolve this problem by raising the max allowed upload limit in one of 2 ways:
First method:
1. Go to SharePoint Central Administration.
2. Go to ” Application Management”.
3. Then go to “Web Application General Settings”
4. Go to the property “Maximum Upload Size” and change the max upload size to whatever you want.

Second method:
This way I found it in the web but personally it didn’t work with me but you can try it also and see if it reflect .
1. Go to your web.config file of your SharePoint site.
2. Change the value of the property maxRequestLength to whatever size you prefer as: <\httpRuntime maxRequestLength="51200" />

The service did not respond to the start or control request in a timely fashion, you need administrator privileges to be able to start the service

Problem:

I was trying to access my SharePoint site and it wasn’t opening, I found that the SQL Server services was not running and when I tried to run it, it failed and generated the error: “The service did not respond to the start or control request in a timely fashion, you need administrator privileges to be able to start/stop this service. (SQLSAC)”

Cause:

I have searched the even log and found the error: “The file "C:\Program Files\Microsoft SQL Server\MSSQL.3\MSSQL\DATA\mastlog.ldf" is compressed but does not reside in a read-only database or file group. The file must be decompressed.” I did search the web and found that the cause of such error happens because all the files related to the SQL under the path “C:\Program Files\Microsoft SQL Server\MSSQL.3\MSSQL\DATA\” was all compressed. This could happen due to many reasons but in my case it happened because I run the windows disk cleanup tool to clean temporary and unused files and this service compressed few files and part of them was the SQL data files.

Resolution:

Simply go to the path “C:\Program Files\Microsoft SQL Server\MSSQL.3\MSSQL\DATA\” or any other reported paths, then right click the file and remove the compressed property then try to run the service again and it will work smoothly.

I guess it’s an interesting one and hope this helps too.
