Apparently ffmpeg can't correctly decode/demux the version 10 SWF file.
Please show us the complete, uncut console output of the above command.

Can you share a sample?

You don't have to; if you give "something%d.jpg" with a recognized
image extension, them image2 demuxer for said image format is
automatically chosen.

That format specifies that a series of single images is to be output
(instead of e.g. just one image).
