Unexpected output when using -v and -report

[dave rice]

Summary of the bug:

I would like to run ffmpeg with verbosity set to warning but also make use of the -report option.

When I run with only the -v warning option I get the desired brief output.

ffmpeg -v warning -f lavfi -i mandelbrot -t 10 -y -stats test.mpeg
[mpeg @ 0x7f9c8c02a800] VBV buffer size not set, muxing may fail
frame=  234 fps= 66 q=31.0 size=     782kB time=00:00:09.28 bitrate= 690.3kbits/s

When I add -report then the verbose report is generated, but also the terminal output becomes more verbose (from 2 lines of output to 14):

ffmpeg -report -v warning -f lavfi -i mandelbrot -t 10 -y -stats test.mpeg

I propose that use of -report and -v together use the verbosity level set by -v for terminal output, but use the standard reporting verbosity (info, IIRC) for the generated log, like this:

ffmpeg -report -v warning -f lavfi -i mandelbrot -t 10 -y -stats test.mpeg
