(qtdump is a command-line wrapper around libquicktime which we used for our recent metadata collection experiment at http://trac.yorba.org/wiki/VideoMetadata). I've just done some more investigation about getting metadata from GStreamer. Specifically, I built the GStreamer metadata dumping program at http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/chapter-metadata.htmland ran it on videos from a couple of cameras. It turns out that GStreamer *can* retrieve the creation date of an AVI video from a Canon PowerShot SD1200, but not from a MOV video from a Canon PowerShot S90. I took a quick look at the GStreamer QuickTime source code in gst-plugins-good and it appears that GStreamer should actually be able to return a date tag for some QuickTime videos, though it didn't work for the one MOV video I tried. We'll continue to investigate. adam _______________________________________________ Shotwell mailing list [email protected] http://lists.yorba.org/cgi-bin/mailman/listinfo/shotwell
