You forgot to include the complete console output from your ffmpeg command as requested. What exactly is wrong with the localtime output?

I can NOT upload picture file.

1.command line 1
When -c:v libx265,the second is very very FAST.

2.command line 2
"Sometime" the second is fast,it is not stable.

Please reopen this ticket if you can provide (paste) the command you tested together with the complete, uncut console output.

localtime is the "time at which the filter is running". If your process is not occurring at realtime then the printed output will be faster or slower depending on the speed of the filter process. This is the documented and expected behavior so I believe this is not a bug.

Feel free to ask the ffmpeg-user mailing list if you need help to print whatever timestamp you need.
