[FFmpeg-user] Is time-stamping report lines possible?

Thank you this explains why I couldn't find anything. I'm stuck with binaries at the moment. I have a workaround of sorts, instead of using report I launch it from another process with a detailed enough loglevel and read stderr there and can time the log lines as they are printed, imprecise but better than nothing.

No, there's no such feature included yet.

A newer, better patch was submitted, but never completed during review:

Unfortunately, the submitter seems to have lost interested, and the
feature never made it into ffmpeg. If you build your own, you can apply
that patch. I do it in my builds, and it works for me.
