How to get encoding time per frame using x265 v1.7?

Using -log-level 4 on x265 v1.4 I get encoding time and elapsed time per frame.

Now using v1.7 I don't get these values in csv. Instead I get DecideWait (ms), Row0Wait (ms), Wall time (ms), Ref Wait Wall (ms), Total CTU time (ms), Stall Time (ms), Avg WPP, amd Row Blocks.

I tried -log-level values 3,4 and 5 and still no luck.

can you help me please?

Solution

  • I found the solution.

    x265 v2.5 now gives the Total frame time (ms) in the csv log file.

    When you run an x265 encoding add the following flag and csv created file location:

    --csv-log-level 2 --csv info.csv

    More info can be found here and here.

    For x265 earlier versions, a rough estimation of the elapsed time per frame is calculated by the summation of DecideWait (ms), Row0Wait (ms), and Wall time (ms).
