[FFmpeg-user] Adding user-defined SEI messages thru libavcodec/libx264

I am searching a way to insert private SEI messages before each picture when encoding with x264. As far as i see from the libx264.c code, it is not supported up to now.
Am i correct ?

If yes, i am willing to push patch to support this, but do you have a preferred way to do this (ie thru medata field of AVFrame ? thru sidedata of AVFrame ? ...)

Thanks for your hints, 

Regards, SF
