Set loglevel for written log file

I would like to suppress info in the console, and write a logfile with -loglevel info. But when the -report option is specified, the written log file always uses the verbose log level, and that's more detail than I want.

$ ffmpeg -loglevel warning -stats -report -i 1.mp4
No pixel format specified, yuv422p for H.264 encoding chosen.
Use -pix_fmt yuv420p for compatibility with outdated media players.
$ Lsize=   14492kB time=00:00:49.85 bitrate=2381.2kbits/s

Afair, the reason for the -report option was to simplify bug reports. If you want to use -loglevel for output to a textfile, redirect your console to a file.

But that will completely suppress console output. When ffmpeg is run in a shell script to batch process files, in a supervised environment, it's very useful to have the single line stats readout so the user has some form of progress display.

The documentation for the FFREPORT variable says it uses a ’:’-separated key=value sequence, but file is the only key defined. Would it be easy to add another key for loglevel there?
