I can not easily check right now, but this should do:

ffmpeg -i test.idx -filter_complex 'testsrc[v];[v][s]overlay[out]' -map '[out]' -f null

The basic condition is that the graph must have a single input from ffmpeg.
For sub2video, that limits the use a lot: on the above example, the moral
input for the output stream is testsrc, not the subtitles.
