Thread: thunar video thumnails

  1. #1

    Default thunar video thumnails

    I am using 13.1 with XFCE. I have tumbler and ffmpegthumbnailer installed. In Thunar I have Preferences -> Display -> Thumnails set to always. I have removed the ~/.thumbnails folder and logged out/in. I can see thumbnails for everyhing except video files.

    Does anyone have suggestions on how to fix this, or suggest a reference or docs.

    Any and all help appreciated.

    Just a thought,
    Have you configured an app association for those types of files? (easiest way to test is to simply click on one of the files and see what app launches to view the file, if any)

    Although not in Thunar, I've observed if you haven't created a file association the File Manager sometimes can't/won't build the thumbnail.

    Guessing,

    File associations are set up, but no video thumbnails.

    I have installed PCManFM and it also does not generate thumbnails for videos.

    OK,
    I did a little experimenting.

    Looks like if you have the proper codecs to play the video locally, then the file manager is able to "open" the video and display a thumbnail. You may also need to specify a specific app to open the video.

    No codecs for that particular video, then no thumbnail.

    Did this testing on 13.1/LXDE/PCmanFM but likely applies to any openSUSE running any Desktop using any File Manager (yeah, in particular generalizing about all File Managers could be YMMV).

    HTH,

    I have a related problem with the shotwell (digital photo organizer),
    which on some installations refuses to display video thumbnails.

    I found an explanation here:

    https://wiki.gnome.org/Apps/Shotwell/FAQ


    +++·································
    I upgraded to Shotwell 0.14.x and now I get bad video thumbnails. This
    used to work. What gives?

    Shotwell uses GStreamer, the standard Linux framework for multimedia
    support, to obtain video thumbnails. Shotwell 0.13.1 and earlier were
    based on GStreamer 0.1, whereas Shotwell 0.14 uses GStreamer 1.0. These
    two versions of GStreamer are substantially different, and they have
    different packages of plugins that determine what video formats they
    support. In general, GStreamer 1.0 is a step forward over GStreamer 0.1,
    but there are some exceptions, mostly having to do with
    patent-encumbered video formats. As a result, Shotwell 0.14 may not be
    able to generate thumbnails for certain videos that Shotwell 0.13.1
    could. Furthermore, video thumbnails generated by Shotwell 0.14 may have
    visual problems like ghosting or artifacting. Many of these problems
    will disappear as GStreamer 1.0 evolves. If you encounter a situation in
    Shotwell 0.14 generates a bad video thumbnail, please report a bug about
    it by following the steps above.
    ·································++-


    However, on this system "Thunar" does show the thumbnails, whereas
    "shotwell" does not. I do not have "ffmpegthumbnailer" installed at the
    moment.

    HTH.

    I can play videos locally. I can double-click on the video file in Thunar. It opens in vlc and plays. No thumbnail.

    I've found this to be true but very specific to vlc not just on openSUSE.
    More than likely, vlc stores and accesses its codecs in a proprietary way, not common to the OS in general.

    I can "Open with Mplayer" in Thunar and no thumbnail. Same in PCManFM.

    The OS probably uses gstreamer.
