Hi all,

I'm looking into vlc modules development and am trying to include a simple delay module into vlc player. I looked through "hacker's guide" and got the basics there but I have some questions, hoping someone can help me.

So I understand, following the simple example, I can just write a delay.cpp where I specify by the template the capabilities, Open, Close, doWork and so on.
The thing is, I have my algorithm already in a static lib. I have a delay.lib (or .a) and fft.lib (or .a) for doing fft transform I need (it's in frequency domain, nevermind that now).

My question is, how can I use my libs directly. I didn't quite get the story with plugins vs modules? Do I need to have a dynamic lib? If so, why is rebuilding of vlc player necessary? Can I just specify an interface file and put the libs there together with header files? with of course adjusting the Modules.am---or what's the general procedure in this case?

Thanks for all the help

You can link a VLC plugin against a static library, but you need to ensure that the library is built as PIC.

See a52tofloat32 for example.

Thanks for the reply Remi,

but I'm not sure I get it.

In the audio_filter/converter folder, a52tofloat32 is no different than other examples? I see some dll's in the libs folder. How exactly can I link my static libs? what would be the correct procedure...

Other thing is, so If I link my libs dynamically, say I have a final dll to use, could I just drop it in the folder there? why would I need to rebuild the vlc player again, which I understood from wiki and some tutorials...(unless I'm wrong)

Thanks for the help

a52tofloat32 links with liba52, which is static (Windows) or dynamic (Linux, usually) depending on the platform.

I'm not getting far hear. Can someone please help me by answering a simple thing..or pointing to the right direction.

How can I add a filter without recompiling it's code..How do I use my existing libs to add an audio_filter, whether it's static lib or dll. If I have a dll what do I do with it?

Thank you very much
