Many of you might have noted that your WinCE 6.0 DirectShow camera application was not working with Windows Embedded Compact 7(WEC7). The reason is "In the newly launched Windows Embedded Compact 7 OS, the Video Mixing Renderer (VMR) filter replaces the DirectShow Video renderer filter as a default video renderer".

In this post I will try to give basic idea to start writing the Simple DirectShow Camera application on WEC7 and also "How to" start with the newly added component in WEC7 (i.e., Video Mixing Renderer (VMR)).

One more important thing is Windows Embedded CE 6.0 DirectShow camera Application will not work on Windows Embedded Compact (WEC7) without the changes which I had done in this post.So check out the post here.

Also check out this codeplex project for the application source code which I mentioned in the above post.

This is the same application which I uploaded before for  post Working with display controller using DDraw APIs in WinCE / Windows Mobile with the modifications done to work on WEC7.

Working with display controller using DDraw APIs in WinCE / Windows Mobile

I had seen few questions in the wince newsgroups about drawing text or drawing any bitmap over the camera video stream output render.I had thought of sharing my experience for this requirement.So I wrote this article with sample demo application and I hope this will help the community who are searching for a solution.

And also take a look at the application source of the sample which is described in the article.I had also created a project for this sample application in Codeplex server.If you have any comments or issues with this application please post it in this blog comments or in codeplex project discussion page,I will try to fix it.
