Comment:
I have a different opinion to this issue.[[BR]]
I see "creation_time" as the time, when the video was originally recorded.
This time should not change on transcoding, so could be preserved. The
file creation time is anyway saved from the underlying OS in the file
system.[[BR]]
If ffmpeg sees the "creation_time" as time of encoding, why doesn't it set
to the current time, but leaves it empty?
Linux tool "mediainfo" distinguishes between "Encoded date" and "Tagged
date". Which one is interpreted as "creation_time" by ffmpeg?
As another distinction in JPEG EXIF we find "DateTimeOriginal" and
"DateTimeDigitized".
The current behaviour prevents -f ffmatadata to report the global
"creation_time", see #8552
