How to use DirectVobSub and Morgan Stream Switcher programmatically? posting, anything, personal, several, success

andy

Hi there!

I'm developping DivX player for my personal use (no pop-up menus,
no skins, no green text displayed on screen while viewing the
movie whenever I do anything...).

After several days trying to find out how to code a certain
functionality without success  I'm posting here hoping you
guys will help me.

Let me explain what I want to do:

For each movie file I have several audio tracks and subtitles,
and I would like to -while watching the movie- hit quot;Equot; key and
hear people talking in english, quot;Squot; and hear spanish, and so on.
The same on subtitles.

The only way I can think of to achieve those functionalities is
by controlling Morgan Stream Switcher Filter and and DirectVobSub
filter programmatically.

My problem is that I have absolute no idea of how to control those
filters from Delphi. I'm begining to learn how to build a graph
programmatically, but when it cames to add those filters and set
them I get quot;doomedquot;. Therefore I would very much appreciate any
kind of guideline about this subject.

Of course I will be happy to know other ways to implement those
features.

Many thanks in advance,

UNICO

I don't know if it's the same with Delphi, but in C/C++ I do the following :

1-Find the correct filter (quot;Morgan Stream Switcherquot;)

2-Query the interface IAMStreamSelect (pMSS is a IBaseFilter):
IAMStreamSelect *pStrm = NULL;   pMSS-gt;QueryInterface(IID_IAMStreamSelect, (void**)amp;pStrm);

3-Now you can access the filter's info   pStrm-gt;Info(...)To enable a quot;streamquot;, you do steps 1 and 2 and :   pStrm-gt;Enable(index, AMSTREAMSELECTENABLE_ENABLE);

where index is the stream you want.If you want some part of my code that query/change Morgan Stream Switcher, just ask.

Hope it help.

Many thanks NoWoL  

Although I'm not a C++ developer, your post has given to me A Lot of information about quot;how it worksquot;.

After taking a look at the DirectX help file I think I have seen quot;the big picturequot;.

Many thanks again, I would have never discovered it by myself.

Bye,
