C#

Read your tutorial for DirectShow and c++. It was great.

I am basically gathering information to develop a player for an in-house channel. Googling lead me to DirectShow .net library. Is this library enough for my requirements. What i need is:

We have a in-house channels of Movies. We want to play ads in that channel. The ads can be a:
1) standalone ad
2) A strip (like news headlines in various channels)
3) An L-shaped ad (like shown in some sports channels)

these ads will be in swf/avi/wmv/mp4 etc formats.

In addition, we want to have a scheduler for playing movies(basically a queue)/ads(managed on timely based)/Logo(for the in-house channel i.e an image or an animated image or video format).

These are the basic requirements for the project.

I am waiting for your kind response.
Regards.
