Do you have the ffmpegthumbs package installed? For many years i used this feature. So all necessary packages are installed. Just before updating to 20.12.0 there was no problem. I'm asking because there is a chance it might have gotten uninstalled. Can you verify that it is still installed? (In reply to Nate Graham from comment #3) > I'm asking because there is a chance it might have gotten uninstalled.

In Dolphin Settings > General > Previews, is there a list item with the text "Video Files (ffmpegthumbs)"> If so, it is checked? Also, what is the value of the spinbox for "Skip previews for local files above:" on that same page?

"no limit" I made an error. There is no more thumbnail for any mp4, ts files old or new. There is an icon with movie thumbnails for each folder icon. How odd. Thanks for the information. i found someone added a new feature about video file preview thumbnail. see https://bugs.kde.org/show_bug.cgi?id=408956 sam. 14 nov. 2020 13:00:00 CET Christophe Giboudeaux <christophe@krop.fr> - Update to 20.11.80 * New feature release - Changes since 20.08.3: * Remove explicit ECM_KDE_MODULE_DIR * remove deprecated/unnecessary call * register our own log handler for ffmpeg using QLoggingCategory * Add missing REQUIRED keyword for Taglib * Use embedded cover in MP4 video files (kde#408956) Today a new fact. No more thumbnail preview for folder icon for folder containing movies. KDE Plasma Version: 5.20.4 KDE Frameworks Version: 5.77 Qt Version: 5.15.2 kde apps 20.12.0 Same here, no more MP4 thumbnails with 20.12. kde apps 20.12.1 << new plasma 5.20.5 << new kde frameworks 5.77.0 << new qt 5.15.2 problem still there problem also with ts, mov, flv movie file And I noticed MKV files are also affected. *** Bug 431397 has been marked as a duplicate of this bug. *** Hello Problem still there with : kde apps 2012.2 kde plasma 5.21.0 kde frameworks 5.79.0 qt 5.15.2 I manage many videos. I discovered with this bug that viewing a thumbnail preview is an important help when searching a video. It's very difficult to find any video. kde gear 21.04.0 plasma 5.21.4 frameworks 5.81.0 qt 5.15.2 Problem still there I just checked this on Archlinux. The necessary package for me to get it working is ffmpegthumbs-21.04.0-1, and I also need to manually enable it in doplhin. After that it just works. Since the report is about opensuse and the only release provides 20.12 in opensuse is tumbleweed, so I just go ahead and try that in the VM and downloaded some random mp4 file. And here's what I found. The error reported in dolphin is "Could not find video stream", so indeed there some error happens. After further investigation, I installed ffmpeg command line to and try to decode mp4 file manually and ffmpeg gives me error for not having h264 decoder. So I think your problem is the ffmpeg build doesn't have relevant codec support. I browsed opensuse repo on pkgs.org and older version of opensuse (15.2) does have libx264 but it's removed in tumbleweed. I also tried ffmpeg in Packman repository which is built with libx264 support. After installing that, dolphin thumbnail just starts to work in opensuse tumbleweed. So I think it's just a packaging issue. I think libx264 is removed from opensuse due to patent, FYI: https://en.opensuse.org/SDB:Firefox_MP4/H.264_Video_Support Hello thanks for your work. I have no problem with Chrome 90.0 or VLC 3.12 to play mp4 videos. I get no problem with firefox 88.0 from mozilla.org. I can play .mp4 file with the player in the data panel. I get no problem with digikam movie preview. I get the problem with Firefox 87.x and 88.0 from download.opensuse.org/repositories/mozilla/openSUSE_Leap_15.2/ I checked that all packages from Packman replace system packages. I checked that ffmpegthumbs is enabled with no limit in dolphin preview settings. Problem still there. How do you explain I get this problem with .flv, .mkv, .mov, .ts files ? Are they just containers with mp4 video part ? Thanks > not having h264 decoder. So I think your problem is the ffmpeg build doesn't have relevant codec support. Happens for any video files, not just h264-encoded. >older version of opensuse (15.2) does have libx264 but it's removed in tumbleweed I have the same bug on 15.2. > ffmpeg in Packman repository which is built with libx264 support With Packman enabled. This is not a packaging change in openSUSE, but a 20.12 regression. The offending commit, as noted above, is most likely https://invent.kde.org/multimedia/ffmpegthumbs/commit/d2ab28b9a4bcc8270ae0e0995710384eec4d46dc thus, my hypothesis in comment #10 would be good. Since can be made to work on some system with given version, it is less likely to be a bug in the package but more likely to be either your system has some misconfiguration or packaging issue. Here's the things I suggest to be checked : 1. Check if dolphin has the video thumbnailer enabled 2. I'm not sure what's your repo setup, leap 15.2 doesn't have 20.12 so are you using mixed packages or additional 3rd party repo? you may want to check carefully if everything matches expectation, and also list all the relevant packages version installed on your system, including libx264, all relevant libav* packages and ffmpegthumbs. 3. While I think it's unlikely to get broken linkage on rpm based system, what is your output of ldd /usr/lib64/qt5/plugins/ffmpegthumbs.so does it show anything "not found"? When you run dolphin from the command line, does it give any error that seems related to "video" or "stream"? 1. in my comment #20 i said I checked that all packages from Packman replace system packages. I checked that ffmpegthumbs is enabled with no limit in dolphin preview settings. 2. i use openSuse 15.2 Argon (an openSuse with latest kde as Kde Neon but with openSuse)

There were never any problem till the update from kde gear 20.08 to 20.12.0. I get also the same problem with all my mpeg-2-ts video files Git commit 26c1d3b790d621f89cf1cbf56bdc0b8c97a95151 by Weng Xuetian. Committed on 25/04/2021 at 21:12. Pushed by xuetianweng into branch 'release/21.04'. Restore the compatiblity with ffmpeg 3. M +4 -0 ffmpegthumbnailer/moviedecoder.cpp https://invent.kde.org/multimedia/ffmpegthumbs/commit/26c1d3b790d621f89cf1cbf56bdc0b8c97a95151 Thanks for the information. I installed leap 15.2 for testing. The issue is removing a call to API deprecated in ffmpeg 4, while the call is necessary for ffmpeg 3 used by 15.2's ffmpegthumbs. I restored the call when compiling ffmpegthumbs with ffmpeg 3. The fix should be picked by the next release 21.04.1. (In reply to Weng Xuetian from comment #31) Thanks. I am impatient to test it. Thank you for investigating this! :) This fix is now in the repositories, I can confirm that it works for me :) no more problem |
