FFmpeg debug verbosity

I'm debugging ffmpeg with -loglevel debug, and I want the debug messages (which are basically just printing to terminal the value of different variables) but in front of each line is the file offset in blue text, and I don't want to see that, because it's useless to me.

How can I do this?

Here's an example screenshot:

I want the blue text [dca @ 0x7fe86c80f000] to be removed, but the green text to stay

I tried -nostats and -hide_banner together and apart, and that didn't work either.

As Nifle commented, you can use sed like this. Without sed, if your output is:

$ ffmpeg -i input.avi -b:v 64k -bufsize 64k output.avi -loglevel debug
here is a line without any brackets and stuff, it should display too
[dca @ 0x7fe86c80f000] leave this stuff here
[dca @ 0x7fe86c80f000] and this
[dca @ 0x7fe86c80f000] this stuff too
another line that should just be printed plainly.

Then you can add

| sed 's/\[.*\] *\t*//'

to the end, like this: (ran on my linux, osX sed may be ever-so-slightly different)

$ ffmpeg -i input.avi -b:v 64k -bufsize 64k output.avi -loglevel debug | sed 's/\[.*\] *\t*//'
here is a line without any brackets and stuff, it should display too
leave this stuff here
and this
this stuff too
another line that should just be printed plainly.

Look good?
