DirectShow Win10

[Vic666]

Hello to all i need to convert the code bellow to a more modern aproach to DirectShow to make a old app work in Win 10 , the ancient code used DirectDraw in the video surface, can this be done in another renderer or DX texture? the app is working in DX8 and the video surface used to be displayed inside DirectX8 in a DirectDraw surface but it stopped working. Can someone help. Thanks a lot.

#include <stdio.h>

Your code is very hard to read/understand. It's because you missed using the CODE tags.
Please, read the Announcement: Before you post....

Sorry about that, i think this is better.

No! Don't you see it is almost the same!?
Code snippet has to be formatted to have the proper indentations, what is not in your post!

[2kaud]

[Code should be properly indented (using spaces or tabs) and formatted before being inserted. I've indented the code in post #3]

Cheers!
