Lower latency

I have tried my best with cmdline:
omxplayer -o hdmi -s --live --audio_fifo 0.1 rtsp://..............   (local network streaming)
However I only get to 1.10 seconds of delay. Video is 720x576p50 H.264 @ 1200 kbps + Audio AAC 96 kbps.
On my PC I can make ffplay -analyzeduration 0 rtsp://.......... and get 0.1 seconds of delay at my SDL output, and I have also tested the /opt/vc/src/hello_pi/hello_video.bin omxil example with no delay on output at all.
So why I am not able to reduce delay on omxplayer is using both avformat and omxil components ?
At least to be neared to the one I get with ffplay

Thanks in advance
