Hi,
I have run My USB Tuner from DirectX filter graphs. My Tv Tuner Card has no FM support and does not provide I/Q samples(Low frequency) as Realtek RTL2832u based USB Tuners, so i need to get RF samples directly from TV Tuner Analog Audio out pin and store it in hard disk for digital signal processing. I am unable to find any information on this topic also the Directx (Graphedit) application does not allow TV Tuner output pins to be connected to its Sample Capture filter. Please provide info with source code example for capturing Tv Tuner output through filter or any other API.

Your best course of action is to purchase a USB tuner that provides IQ sampled data. Your TV tuner's driver likely doesn't support IQ samples and I don't think Direct-X was ever designed for this.

A Realtek RTL2832U USB tuner device can be purchased for USD $20 or less (and there are over a dozen free programs that support them). Keep your USB tuner for watching TV.
