    .net fm radio/tv tunar

    Hello all, I did a search in the forum to see what other developers had to say about implimenting FM radio into thier applications and I didnt get too much.


    I'd love to write a tv/am/fm app. I started at MSDN looking at directshow and I didnt get too far. basically i'm at a stand still as far as looking for what I need.

    Anyone caaaare to point me in the correct direction ??

    The way I did it was create classes wrapping the DirectShow technology I needed in managed C++ and then call those from C#. It is working out great and seems to be very fast. I am actually surprised at the performance. Way better then the first way I did it, which is wrap DirectShow using COM interop wrappers.

    So I would recommend this way. Just my .02 cents.

    Thanks

    DirectShow is the way to go, but it is probably one of the most complicated SDKs you'll ever work with. Particularly when you get into tuners. Radio tuners are very poorly supported in directshow, however, I don't know of any other sdk that isn't hardware specific for them so your pretty much stuck.

    Theres only two books, that I know of written on DirectShow. This is the one you want:
    http://www.microsoft.com/MSPress/boo...=0-7356-1821-6 the other one is garbage.
    Your not going to find too much documentation or help on directshow or even programming TV applications. I almost never buy programming books cause I can find all the stuff online, this was the exception and is the only book I ever had to buy just for reference purposes.

    You can use directshow in VB, but you'll be extremely limited in what you can do. The best language for directshow is probably C++, I don't even thing the newer .Net languages allow the same level of access to directshow, particularly if your writing filters. If all you want to do is a very simple app, i.e. show TV, change channles, you can probably get away with VB. There are also some OCX controls that you can use for this, hauppage has one specifically for thier cards.

    .net tv/fm

    Yea, I've been browsing the directshow sdk and it really is aweful. Not much support and little to no examples.

    I basically want a simple app to listen to FM radio and watch some basic tv channels. I'm considering that book though for referance usages that was so very helpful !

    One thing I can curse .net for is that its so new not much support is out there for anything..

    I'm kinda frustrated with the switch, from vb6 to .net the learning curve was rough but I really do like .net and its something I want to make this project work with.
