My point was that I first claimed -t was only an output option. It was an output-only option until 2014. As such, specifying "-t x -i file" only worked "by chance" (actually because if only one output file was specified FFmpeg interpreted the -t as if it was specified as output option for the first output file). A warning was shown at least for some time. I then realized that -t used to be an input option until around 2011 (iirc).
