Development request for encoding timings in logs

[digitensions]

Hi Jérôme and all,

During recent timing trails with RAWcooked 4K encoding we've been attempting to capture duration of encodings that includes the RAWcooked analysis and FFmpeg encoding activities. We've used GNU parallel --joblog, but this updates the logs frequently overwriting data, so it's proven a little awkward. Had no luck using time on the GNU parallel command line either, the logs didn't pick it up.

I think it might be useful to have an option for encoding timings to be output to the console at completion of the mux/demux, so they can be captured in our logs.

Many thanks, Joanna
