Since you are not the first one who tries this:
Why do you think this should work? (It does not.)
Is this documented somewhere?
I am not saying it cannot be made to work but since 
two working alternatives exist, I don't think 
this should have a high priority, but maybe I am 
missing something?

Please use ffmpeg -start_number 3556 -i 0%4d.sgi 
for 1_CrowdRun_1080i25_CgrLevels_SINC_FILTER_SVTdec05_

(It also works with the rawvideo demuxer and -video_size 
but using image2 as in my example is recommended.)
