Original description:

Shotwell 0.8 generates video thumbnails by using GStreamer directly.
Unfortunately we've found that this occasionally hangs for certain obscure
videos. We've fiddled with GStreamer parameters (including the 'flush' flag),
but haven't found a set of parameters that works reliably for all videos.

Nautilus generates video thumbnails by calling totem-video-thumbnailer. Eric
has spent some time trying to tweak our video thumbnailing code to look more
like the code in totem-video-thumbnailer. Unfortunately that code is
complicated and looks like it contains various workarounds for GStreamer bugs,
and I don't think we want to try to duplicate that.

I've become convinced that in the short term, i.e. for 0.9, we should generate
thumbnails by calling totem-video-thumbnailer ourselves. This will have two
benefits:

We can reuse the existing thumbnailing code rather than trying to duplicate
it.

If we find that totem-video-thumbnailer ever hangs, we can put in a timeout
that kills it if necessary. Doing so on GStreamer code running in our own
process would be much more dangerous.

In the long term, I think we should do either of these:

convince the GStreamer developers to fix their bugs (or help them do so) so
that we can simply call GStreamer in-process as we originally tried

enhance the GNOME thumbnailing API (which calls totem-video-thumbnailer behind
the scenes) so that we can ask for a JPEG thumbnail at an arbitrary
resolution; then we could simply retrieve our thumbnails using this API

Done. We're now dependent on totem for those who want thumbnails of their
videos.
