[Libav-user] AVFilter modify parameters

[Ronak]

Hi,

As I mentioned earlier, I'm trying to use the AVFilter libraries to build a graphical equalizer in an iOS app.

The user will have the ability to manipulate the equalizer settings while audio is playing back. However, I don't see an API on AVFilter so I can manipulate the gain settings.

Therefore, it feels like I would have to recreate an equalizer AVFilter and rebuild the graph.

Is that the recommended way to go about this?

Thanks,

Ronak
