Optimal H264 parameters for high speed encoding with P-Frames?

Other Parts Discussed in Thread: OMAP3530

Hello,

I am developing a H264 real-time encoding application with DVSDK4 for OMAP3530. The encoder build ID is 2.01.013.
So far, the encoding process works fine and by only using I-frames, a PAL D1 video signal with 30 fps can actually be encoded in real-time. The resulting file size is - what a surprise - quite high.

I experimented with the extended parameters for quite some time now, but I wasn't able to get the same encoding speed with P-frames enabled. Rate control and encoding presets are both set to user-defined. Can you recommend parameter settings, so that I can use P-frames and still encode at 30 fps? If it is possible...

Best regards,

Andreas
