 Summary of the bug:

 FFmpeg can produce periodic progress information using e.g. "-progress
 pipe:1", which produces key=value pairs like below. The value for key
 "out_time_ms" however is not in milliseconds (ms) but in microseconds,
 which is abbreviated with "μs" - sometimes "us" may be used for
 convenience but "ms" means something else.

 frame=391
 fps=97.0
 stream_0_0_q=28.0
 bitrate= 162.8kbits/s
 total_size=262192
 out_time_ms=12885333
 out_time=00:00:12.885333
 dup_frames=0
 drop_frames=0
 speed= 3.2x
 progress=continue

 The key out_time_ms is incorrect as "ms" is the abbreviation for
 milliseconds but the value shown is actually in microseconds. The correct
 abbreviation for microseconds is μs or one might use "us", as the Ancient
 Greek μῦ [mŷː] might be inconvenient for people to use.

 Or you change the value to a float showing milliseconds instead. Either
 way, a correction is needed.

 How to reproduce:
 You can reproduce that with any transcoding operation.
