Bug ID: 357972 Summary: Video Thumbnails are not produced anymore Product: digikam Version: 4.14.0 Platform: Archlinux Packages OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: Thumbnails Assignee: [hidden email] Reporter: [hidden email] I noticed a while ago ( two months ) that DigiKam did not mark the video clips with the usual "Filmstrip" effect. Now ( 2016-01 ) the thumbnails are just not produced at all. Reproducible: Always Steps to Reproduce: 1. Save film clips in a directory 2. Point DigiKam at the directory 3. Watch the mplayer process chew away at the clips for a while 4. No update on the thumbnails in the icons Actual Results: Icons are not converted into thumbnails of the clips. Expected Results: Thumbnails, with the usual filmstrip effects -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

Maik Qualmann <[hidden email]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[hidden email] --- Comment #2 from Maik Qualmann <[hidden email]> --- From README: digiKam do not have any video thumbnailer. Video support is delegate to KDE. To support Video thumbnails, please install "ffmpegthumbs" package, which is the kdemultimedia Video thumbnail generator for KDE4 file managers. Your thumbnails in Dolphin could be loaded from the cache. Appear new video thumbnails in Dolphin?

--- Comment #3 from Evert Vorster <[hidden email]> --- ffmpegthumbs package is installed. Dolphin is creating the thumbnails on demand, as I was watching it read the files and pop the thumbnails in over time. I'm thinking that this may be more of an Arch issue, as Arch is moving over to QT5, and digikam used to work until a recent system upgrade. I am now installing DigiKam 5.0.0 from git. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

[hidden email] changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[hidden email] --- Comment #4 from [hidden email] --- exactly. Dolphin use Desktop standard cache mechanism (PNG thumb file stored in your home dir). DK do not use this mechanism since a while, but a dedicated database to optimize a lots the space used to store thumbs (wavelets compression) and to be able to show thumbs with disconnected media managed with DK. In Dolphin, press F5 to refresh video thumbs. Does it work ? Note : DK and Dolphin share the same engine to extract video thumbs. Engine is provided by KDELibs (as an interface), which use a low level extractor as mplayer (configurable in KDE control panel) Maik : the video thumb handling is a big mess in KDE and very sensible to system update and settings. With Qt5, we will wait a method to be able to extract video thumb with QtMultimedia. As i know this still in TODO list for Qt team : see on bottom of https://wiki.qt.io/Qt_Multimedia Gilles Caulier -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

--- Comment #5 from Evert Vorster <[hidden email]> --- When I first navigate to the directory, the thumbnails are generated on demand by Dolphin. The video files are 3.5Gb each, so this takes a little while. If I then hit f5, I can see the icons instantly refresh, so there must be some caching going on. When I hit F5 on the directory in DigiKam, I can see the mlayer process start up, and chew through the files, but for some reason the icons are not updated. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

--- Comment #6 from [hidden email] --- DK has a dedicated DB file named thumbnails-digikam.db. Remove or rename it (it's safe) and restart DK. It's safe : DB file only contain wavelets compressed files, no other data.

--- Comment #7 from Evert Vorster <[hidden email]> --- Hi there. I tried removing the thumbnails-digikam.db file, and DigiKam did not re-create the missing thumbnails. I did notice that DigiKam 5.0.0 makes the thumbnails properly. I encoded all the extra metadata into my images directly, so I am going to start with a clean database on DK 5.0.0 Like I said, Arch is moving away from QT4, so things using it are going to start breaking. I'll just use DK 5.0.0 from git until it's a stable package in Arch. Thanks for looking into this, but I think we can close this bug. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |
