[libav-api] Extract RTCP stats from AVFormatContext

I work on an open source Audio/Video communication software sending/receiving RTP streams. RTCP is enabled and RTCP reports between peers are successfully exchanged over network and given to ffmpeg.
I would like to regularly extract RTCP report in my app to monitor for example packet dropping. RTPStatistics struct looks to be good.
I looked to ffmpeg code and could not find a way to expose it from AVFormatContext . I would like to do something like this :
RTSPState* rtsp_state = (RTSPState*) <my AVFormatContext struct> ->priv_data;
RTSPStream* rtsp_stream = rtsp_state->rtsp_streams;
RTPDemuxContext* rtp_demux_context = (RTPDemuxContext*) rtsp_stream->transport_priv;
RTPStatistics stat = rtp_demux_context->statistics;
But all those struct are not exposed.
Could someone tell me if I am wrong ? Would it be a good idea to expose it by av_dict_set ?
