hello
I am looking for an example or some code in pascal
 To connect a USB TV capture card with bda driver.
it isn't wdm driver and not in video capture directshow
I've seen codes are in c but do not understand this language
What I want is to find a channel digital tvl and see the quality and
signal level
And if you can see that channel would be better still
Thank you very much

Is there any API header and lib for C for your tv tunner? If yes, then
you can use h2pas to convert the header (prepare to face many syntax
errors).

Hello,

BDA is not very compatible between manufacturers, you can have a lot
of troubles specially initializing the card and tunning a frequence.
Almost all available codes are for Delphi or C. You can take look at
http://www.progdigy.com/forums/viewforum.php?f=1 but it is 100%
Delphi.

PS: Quality and signal meters are not reliable and not compatible
across hardware and driver. BDA is a very bad design

I'm very new to lazarus. I tried it on but I did h2pas error in the
first line in the declaration of class
I have seen these components dspack
I've been testing some things but I have not gotten anything yet
Thank you very much
