H264 dynamic targetbit rate BUG. Doubling output rate.

On a DM368 system using the h264 encoder ( main profile, probably also other profile), with different rcAlgo's etc.

when I change the dynamic targetBitrate every frame (with 1 bit) the output bitrate   DOUBLES.

It seems that changing the bitrate does something like doubling the target allocation of bits for a frame.

Also changing once with 1 bit will give a local noticable peak in the bitrate .

And as said changing the bitrate every frame (+-1 bit) doubles the output bitrate.

Could there be something counted double in the TI code?

Note bitrate must be different at least one bit from the last update to have this behaviour.
