With loglevel verbose, I get:

I wonder why ffmpeg doesn't trip over this first. Whatever.
-f is paired with -i and file.ts is interpreted as output URL so
-filter_complex gets correctly paired with its arg.
Well understood. However I was wondering about the order of evaluation,
and somehow expecting

[NULL @ 0xbdaf800] Requested output format '-i' is not a suitable output format
but ffmpeg certainly has its reasons for this order.

-filter_complex is a global option, so parsed first, then input files, then the complex filtergraphs are set up, then output files.
