If you use the current CVS you can use the existing CIF definition  and add

codec.SetMaxBitRate()

to <yourEndpoint>::OpenVideoChannel() 

on the encoder side there is a call back to the codec to limit the sending bitrate to 256k (which will limit the CIF frame rate in this case)

on the decoder side there is a flow control request sent after the OLC to limit the remote sending to 256k

Subject: Re: [h323plus] H264 PLUGIN In H323Plus

Hi All,

Currently, I am working on H.264 codec to limit it's maximum video rate always less than 256kbps.

I use the settings as below:
----------------------------------------
Profile: baseline profile
Level: 1.2
resolution: CIF resolution
frame rate: 10fps.

However, In the H.264 Recommendation, the level 1.2 has default value maximum bit rate with 384kbps.
So, anyway to customize my H.264 codec (or do setting on my x264 encoder) to produce the video size
always less than 256kbit / sec.

Thanks.
