how to use "--record-and-pipe"?

[raekuul]

Description

I'm trying to use the --record-and-pipe flag to both save a stream to disk and watch it as it's being saved (the cli invocation is streamlink <url> <quality> --record-and-pipe "./test.ts" | ffplay -i -, but it's throwing a "cannot use record options with other file output options" error. Do I just have the options in the wrong order, do I need more/less/different options, or is this actually an option that cannot be used?

It works exactly as described here:
https://streamlink.github.io/cli.html#cmdoption-record-and-pipe

Are you by accident loading a config file which sets other arguments?

Post the --loglevel=debug output.

Thank you, that got me to find the problem - since this config is reused across multiple machines with different players, I had added "stdout" as one of the options in the main config (and forgotten that I had done so).
