How to merge three videos on one screen with ffmpeg

I want to merge 3 videos using ffmpeg. My new video should be similar to this: enter image description here

Videos have no sound at all.

My video resolution is 560x448 with frame rate 25fps.

My script is: 

ffmpeg -i C_L_560x448_40_static_maxSSIM_QP23_B2.avi -i maxSSIM_realTime_C_L_560x448.avi -i C_L_560x448_40_static_maxSSIM_QP31_B4.avi -filter_complex "[0:v][1:v][2:v]hstack; format=yuv420p[v];" -map "[v]" -map "[a]" -ac 2 output.avi

but I get [AVFilterGraph @ 00000000007335c0] Too many inputs specified for the "hstack" filter. Error initializing complex filters. Invalid argument

You need to specify inputs for these multi-input filters if the number is different than the default value, typically 2.

-filter_complex "[0:v][1:v][2:v]hstack=3,format=yuv420p[v]"

(I see no filter output labelled [a]. I assume you've omitted that)
