libx264 - Setting up AVCodecContext for HD & SD capturing

I'm trying to configure the AVCodecContext properly in order to capture HD in real-time (1080i) and SD (720 x 576) - also interlaced. I'm using libx264 with the ffmpeg static lib on Windows OS. If anybody can help with flags, gop_size, max_b_frames and all other AVCodecContext's members...

For example, I guess I should have CODEC_FLAG_INTERLACED_ME | CODEC_FLAG_INTERLACED_DCT flags set. However, what I need is the whole story on how to set all this up.

If you are aiming for real time encoding, just use:

x264_param_default_preset(&param, "ultrafast", "zerolatency");

This will set what you need. You may want to set VBV parameters on top of this if you have bandwidth requirements.

Don't set any options unless you know they're already not right for you. libav 0.8 sets everything correctly by default.
