which_recorder.pl parses the backend log file and outputs information on which capture card was used to record shows, formatted for inclusion in the backend status page.

Usage

which_recorder.pl /path/to/backend/log/file

Because which_recorder.pl displays information about all recordings in your log file, you'll probably want to rotate your log files occasionally.

If you have multiple backends, which_recorder.pl will only show information about shows recorded on the backend that runs the script (or, technically, only shows information about shows described in the log file specified, so you could have a slave push its log file to the master occasionally and run the script twice--once for each log file--but that's an exercise left for the reader).
