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?
