I spoke too soon, it's still slow. However, not because of anything in thumbnailer, but because gstreamer takes a long time to extract a thumbnail.
The code we use to extract thumbnails is in lp:thumbnailer, in the src /vs-thumb directory. It's only a few dozen lines long. ** Also affects: gstreamer (Ubuntu) Importance: Undecided Status: New ** Changed in: gstreamer (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1428558 Title: Thumbnailing videos taken by camera is very slow (over 5 seconds on BQ) To manage notifications about this bug go to: https://bugs.launchpad.net/thumbnailer/+bug/1428558/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
