Creation_time extracted from video container

[jackson80]

Greetings,

I am trying to determine if I can get creation_time from a video file using gstreamer.

I know I can get it using ffprobe but I cannot seem to find a way using gstreamer.

Searching the code, I know the gst-libav library has the ffmpeg library.

Can this be done in gstreamer through a program call? (Not command line).

I want this to display the clock capture time of a video, not just 0 counting up to X minutes.

Thanks,

Jack

Hi Mikl,

Yes, I was able to get that to work for me, but including all the necessary libraries makes my program grow from 50k to 79Mb. So my problem is solved, I just want to figure out how to simply open the file and read the data.

I can tell you it is pain - different formats store it in different places.

Lucky for me I have a limited number of formats to deal with, here is what I currently use:

discoverer = GstPbutils.Discoverer()
d = discoverer.discover_uri('file://{}'.format(pathname))
tags= d.get_tags()
dt=tags.get_date_time("datetime")[1]
