[Libav-user] AudioToolbox AudioBufferList to/from AVFilter

[Ronak]

Hi,

I'm trying to build a graphic equalizer using the ffmpeg library for iOS, wrapping the AVFilter library in an AUAudioUnit.

I'm having trouble figuring out how to convert an AudioBufferList's data to an AVFilter and back. The input buffers are in stereo, so I'm also unsure how to pass in both data arrays.

Does anyone know how to do this?

Thanks,

Ronak
