[FFmpeg-user] How can I solve multiple audio + video mixing and overlay problem

[Jeromy]

Hi, please excuse me for bad english.
I need to create six overlayed video (and it included six mixed audio, too).

And I wanna that 
1. Input is 12 audio and videos 
(6 are only audio stream included, and 6 are only video stream included
files).
2. Output is 4 RTP stream 
(1,2 is same thing - mixed all audio stream 3,4 is same thing - overlayed
all video).
3. Output video structure is below.

In order to do this I use following command:

./ffmpeg -i 1.mp3 -i 2.mp3 -i 3.mp3 -i 4.mp3 -i 5.mp3 -i 6.mp3 \
-i video1.mp4 -i video2.mp4 -i video3.mp4 -i video4.mp4 -i video5.mp4 -i
video6.mp4 \
-filter_complex \

[base][iv0]overlay=1 \

[tmp1][iv2]overlay=1:x=852[tmp2]; \
[tmp2][iv3]overlay=1:y=360[tmp3]; \
[tmp3][iv4]overlay=1:x=426:y=360[tmp4];\
[tmp4][iv5]overlay=1:x=852:y=360[tmp5]; \
-map [a1] c:a mp3 -f rtp -y rtp://111.111.111.111:11111 \
-map [a2] c:a mp3 -f rtp -y rtp://222.222.222.222:22222 \
-map [v1] c:a libx264 -f rtp -y rtp://333.333.333.333:33333 \
-map [v2] c:a libx264 -f rtp -y rtp://444.444.444.444:44444

but It doesn`t work...
