Description Jean-François Fortin Tam 2012-01-03 18:58:01 UTC
Initially in pitivi as bug #432661, with the port to GES now it would make more sense for gst discoverer to be the one to actually generate video thumbnails according to the fdo spec [0][1].

Perhaps totem-video-thumbnailer could be called, or perhaps totem's code could be upstreamed.

Comment 1 Vincent Penquerc'h 2012-01-17 18:00:22 UTC
That doesn't seem like a good fit for discoverer to me, though I heard that floated before.
FWIW, I believe ges-launch has that ability, which may be better for you since you mentioned a port to GES ?
Comment 2 Tim-Philipp Müller 2012-01-17 18:12:56 UTC
It plugs decoders anyway, so it may just as well support screenshots/thumbnails ..
Comment 3 Jean-François Fortin Tam 2012-03-03 15:49:36 UTC
The port to GES uses pbutils.discoverer. "ges-launch" is not used in applications such as pitivi.

Technically, individual applications like pitivi could do the thumbnailing themselves... but really, I think the discoverer might as well do it (it's kind of the point of its existence: doing less work in applications downstream).
Comment 4 Jean-François Fortin Tam 2013-06-19 04:24:09 UTC
I doubt you folks would use this particular tech, but just for the record: it seems that Nautilus, in nautilus-thumbnails.c, calls "gnome_desktop_thumbnail_factory_generate_thumbnail" which means it's offloading that work to the libgnome-desktop library, which would be https://developer.gnome.org/gnome-desktop3/stable/GnomeDesktopThumbnailFactory.html
