    Video Previews

    KDE 3.5

    There are (repositories):

    libarts1-xine; aRts plugin enabling xine support
    This package contains aRts' xine plugin, allowing the use of the xine
    multimedia engine though aRts.
    mplayerthumbs; thumbnail generator for video files on Konqueror
    MPlayerThumbs is a thumbnail generator for video files on
    Konqueror. Unlike the original konqueror plugin (libarts1-xine),
    it depends on neither xine nor arts, instead it uses only
    mplayer. You can take advantage of this on x86_64 systems,
    where you can use a 32bit mplayer to load win32codecs.

    Homepage: http://kde-apps.org/content/show.php?content=41180
    You may also need to enable: Konqueror > Settings > Configure Konqueror > Previews & Meta-Data (allow previews)


    KDE 4

    For KDE 4 there is (not in the repositories - maybe soon ?)

    KDE-APPS.org > MPlayerThumbs
    Version: 1.0

    Description:
    MPlayerThumbs is a video thumbnail generator for KDE file managers (Konqueror, Dolphin, ...) , now available also for KDE 4.
    It needs mplayer (of course) to generate thumbnails, and it contains no linking to any library, so in a x86_64 system you can freely use the 32bit mplayer binary with win32codecs by configuring the application launching the mplayerthumbsconfig helper application.
    It catches a random frame from 15% to 70%, checking also how contrasted is the image, and dropping bad frames.

    Changelog:
    2008-06-20 MPlayerThumbs 1.0
    * First stable release
    * Porting to KDE 4
    * Refactoring code, for more stability and speed
    * Also KDE 4 adds for us a free feature, random thumbnail generation on
    the preview on the information toolbar on each mouseover Wink

        High CPU load with the MPlayerThumbs 1.2

        If the MPlayerThumbs is trying to make thumbnails from the partial files there will be problems:

        doesnt work on growing files by mhogomchungu

        i noticed that mplayer goes crazy when trying to create an image on a growing file.

        how to test it.
        open up konqueror on a download folder and then start downloading a video file using firefox and an infinite mplayer instances will be started slowing down the system to a crawl

        browsing away from the folder and all these instances of mplayer will start disappearing, one at a time
        Workaround:
        Re: doesnt work on growing files by RockMan81

        I'm looking into it, but it seems to be a kdelibs/kdebase problem look the number of kio_thumbnail processes too... it's not mplayerthumbs launching multiple mplayer sessions, it's kde launching multiple mplayerthumbs sessions (each one with about one instance of mplayer).
        As a temporary workaround, try adding "part" to the blacklisted extensions.

        Blacklisting: Alt+F2 and "mplayerthumbsconfig". The configuration window will pop up.

          kffmpegthumbnailer

          > kffmpegthumbnailer - KDE-Apps
          > kffmpegthumbnailer - code.google

          kffmpegthumbnailer is a video thumbnailer for kde based on ffmpegthumbnailer. The thumbnailer uses ffmpeg to decode frames from the video files, so supported videoformats depend on the configuration flags of ffmpeg.

          This thumbnailer was designed to be as fast and lightweight as possible.

                It depends (these are subjective things):


                What do you have ? (low/high end computer - here low end)

                - the mplayerthumbs needs lot of CPU power - it is slow at here.

                - the kffmpegthumbnailer and the z166-kde4-ffmpeg-thumbnails (1) are equally fast and light.


                What do you want ?

                - the mplayerthumbs (2) can show continous preview images when you hover the mouse pointer over the icon.

                - the mplayerthumbs can thumbnail everything the mplayer can play.

                - the z166 can thumbnail a bit more than the kffmpegthumbnailer.
                - the z166 is showing more black thumbnails than the kffmpegthumbnailer.


                It depends = you need to test.


                (1) z166-kde4-ffmpeg-thumbnails-0.1 later z166
                (2) mplayerthumbs-alternative (3) can't show continous preview images with the KDE 4.4.
                (3) mplayerthumbs-alternative:
                This is a recompile of the mplayerthumbs (1.2) from the Kubuntu 9.04.
                This version is faster than the mplayerthumbs (1.2-kde4.3.2-0ubuntu1) or mplayerthumbs (4:4.4.0-0ubuntu1).

                  Thank you Rog131

                  the mplayerthumbs and z166-kde4-ffmpeg-thumbnails are working just great.

                  and yes the mplayerthumbs dose use the CPU .........but onley for a few moment's then it calms down

                  strangley the kffmpegthumbnailer would not produse a option in...... Dolphin/Konqueror > Settings > Configure Dolphin/Konqueror > General > Show previews for.........

                  wether installed from synaptic or with your ppa packages and Gdebi

                  but the other 2 work a treat

                    Hmm - strange

                    A .desktop (> GtoK: .desktop files) file should be enough to show the option.




                    A)
                    Did you log out-log in after the installation ? - sometimes this is needed to get the KDE register new applications.

                    B)
                    With the kffmpegthumbnailer do you have ?
                    /usr/share/kde4/services/kffmpegthumbnailer.desktop
                    and
                    /usr/lib/kde4/kffmpegthumbnailer.so

                    C)
                    Have you tried with the Lucid (KDE 4.4) package ?

                            => The "ThumbnailerVersion" is not set


                            Summary: Thumbnails made by the "mplayerthumbs" are replaced by the "kffmpegthumbnailer". And the "ffmpegthumbs" is replacing thumbnails made by the "mplayerthumbs" or the "kffmpegthumbnailer".


                            Uniform appearance

                            It is possible to mix the different thumnails made by the diffrent thumbnailers if the "ThumbnailerVersion" is same in the video thumbnailer desktop files.



                            But the outlook is incoherent. The mplayerthumbs is using a stripe on the left edge.
                            The ffmpegthumbs (~kffmpegthumbnailer) is using the crapes on the both edges.

                            With small changes it is possible to set the thumbnailers to make uniform thumbnails.

                            - The filmstrip pattern has been disabled as default.
                            - The mimetype icon is blended over the preview image.
                            - Set the ThumbnailerVersion=1

                            Mixing thumbnailers - removing selected thumbnails

                            The thumbnails are in the ~/.thumbnails/large/ and ~/.thumbnails/normal/. Thumbnail name is the MD5 hash for the file URI > Thumbnail Saving

                            With the non "ASCII" directory/filenames the URI should be escaped/encoded (space is %20 etc...) before the MD5 hash.



                            File is /media/sda6/Temp/MD5 test ÄÖÅÜ.mov

                            The exif information of the thumbnail is telling:
