FFMPEG - Get creation and/or modification date

Question

I'm trying hard to get the modification date from a MP4 file hosted on my server.

I tried the following library:

ffmpeg -i video.mp4

Without any luck. All I get is duration and a few other fields but I'm not able to get modification date. I tried ffprobe as well and it is not there either.

Any suggestions??

Thanks a lot

Answer 1

Get creation_time with ffprobe:

ffprobe -v quiet input.mp4 -print_format json -show_entries stream=index,codec_type:stream_tags=creation_time:format_tags=creation_time

To view all tags:

ffprobe -v quiet input.mp4 -print_format json -show_entries stream_tags:format_tags

I can't find any reference to modification_time so consider using exiftool or mediainfo.

Answer 2

A simpler alternative to aergistal in terms of output is

$ ffprobe -v quiet -select_streams v:0  -show_entries stream_tags=creation_time -of default=noprint_wrappers=1:nokey=1 input.mp4

which will just print the creation time like so:
