Summary: [qtdemux] report creation/modification time via
metadata tag
Classification: Desktop
Product: GStreamer
Version: 0.10.25
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-plugins-good

A QuickTime movie may have metadata indicating a creation time and/or
modification time. The qtdump command-line program (which uses libquicktime)
can reveal these times:
% qtdump '/home/adam/Desktop/sample.mov' | strings | grep time
quicktime_dump
creation_time 2010-11-15 03:32:15 (3372665535)
modification_time 2010-11-15 03:32:15 (3372665535)
...
But it appears that the qtdemux GStreamer element can't report these times via
metadata tags. I built the sample metadata reading program whose source code
appears at
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/chapter-metadata.html
. When I run this program on the same QuickTime movie, the creation time does
not appear:
adam at adam-desktop:~/test$ ./tags 'file:///home/adam/Desktop/sample.mov'
Got tags from element qtdemux0:
video-codec : H.264 / AVC
language-code : en
Got tags from element qtdemux0:
audio-codec : Raw 16-bit PCM audio
language-code : en
Got tags from element qtdemux0:
private-qt-tag : buffer of size 20
container-format : Quicktime
adam at adam-desktop:~/test$
(I recorded this movie using a Canon PowerShot S90 camera. I'll attach it here
if Bugzilla will let me.)
