Use kdemultimedia-ffmpegthumbs (or kdemultimedia-mplayerthumbs) instead.

[SOLVED] KDE3: Konqueror and video thumbnails

Hello everyone!
I have ArchLinux + KDEmod3 installed with the latest updates and I have a problem with the video thumbnails in Konqueror. By default it shows the first frame of video as preview and it is rather ugly. Most commonly it's just a black screen or something like that. I searched the Internet and found a solution - mplayerthumbs http://www.kde-apps.org/content/show.ph … tent=41180. Package from AUR requires kdelibs from KDE4, so I decided to compile it from sources. It has been compiled and installed successfully. But here is the problem: Konqueror still shows previews made from the first frame! Even if I delete contents of ~/.thumbnails, the same previews will be generated. But article on kde-apps.org says that "It catches a random frame from 15% to 70%"
So how can I fix mplayerthums or is there any other way to get nice video previews in KDE3?
Thank you.

I think solution from AUR package's page will help:
To resolve this, you have to edit the file "videopreview.cpp". Add "#include <stdlib.h>" at the top and the pakage works again.

[SOLVED]Nautilus not "zooming" video thumbnails

Hi!
When i set Nautilus to more than 100% "zoom", the icons of video files get bigger but the thumbnails drawn on them stay the same size, so the video files look like a big white rectangle with a small (regular sized) thumbnail in the middle of it.
Setting Nautilus to less than 100% zoom has video thumbnauls scale down correctly. Inside the .thumbnails folders, the png's belonging to videos and other files look both ok and exactly the same way, but the ploblem only occurs with actual video files.
I noticed, that pictures in big folders first show the same way, shortly after the thumbnails are generated - but they are shown appropriately after a few seconds and video file icons stay that way permanently no matter what.
Any idea how to solve that? thx!

Found inside: abs/extra/libgnomeui
File: gnome-thumbnail.c
changed:
size = 128;
if (factory->priv->size == GNOME_THUMBNAIL_SIZE_LARGE)
size = 256;
...to:
size = 256;
if (factory->priv->size == GNOME_THUMBNAIL_SIZE_LARGE)
size = 256;
compiled, restarted nautilus: WORKING FINE NOW
But i don't think this is like it's supposed to be (and I've got no idea what else I changed by doubling that value). So, whatever that part I altered does - shouldn't there be something like...:
size = 128;
if (factory->priv->size == GNOME_THUMBNAIL_SIZE_LARGE)
size = 256;
if (factory->priv->size == GNOME_THUMBNAIL_SIZE_LARGEST)
size = 512;
or something?
Well, I've got got big thumbnailed video icons again, so I'll leave all the sourcecode I don't understand alone for a while now. I'm not marking this thread as "solved" yet, as the method I used to get where I want is most likely very, very, very wrong.
(edit: jupp, still working after reboot. source messy, thumbnails big, me happy. )

[SOLVED] No video thumbnails in 'Nemo' after update 1.8.5-1 2.0.*

Some week ago Nemo was update from 1.8.5-1 to 2.0.0-2, and after that Nemo could not create new video thumbnails.
I downgrade Nemo to 1.8.5-1 (and gnome-desktop 1:3.10.1-1 to 1:3.8.4-1) and then video thumbnails work again. I have tried every new Nemo version since, but it's the same.
I only use Openbox, no DE. And I use ffmpegthumbnailer.
Does anybody have an idea of what could be wrong..?
EDIT [SOLVED]:
I found a hint here that pointed me in the right direction: http://forums.linuxmint.com/viewtopic.p … 95#p737221
The problem was that under:
Edit > Preferences > Preview > Other Previewable Files > Only for files smaller than: >
it was set to '1 MB', edit that to a bigger size solved my problem, and my video thumbnails is back again!

[SOLVED] [DidiKam] How can I get video thumbnails?

I use DigiKam 1.0 from Extra under Xfce and it works fine. However it doesn't show video thumbnails.
According to http://www.digikam.org/drupal/node/143, DigiKam should be able to handle it:
Digikam uses KDE to generate thumbnails and KDE rely on aRts to do that.
So, you should check your aRts configuration. ARts can use xine plugin for video files, so try if xine is able to play your video files. You may have to use additional codecs (eg libxine-extracodecs on debian/ubuntu if you already have libarts1-xine) for that.
Try also to play your video files using xine (if libarts1-xine is installed).
Remember that if it doesn't work in konqueror, it won't work in digikam...
I couldn't find anything related to aRts in Yaourt. I installed xine but that didn't help.
Is there a simple way to add video thumbnails on DigiKam when running XfCE?

You are the man!
pacman -S kdemultimedia-mplayerthumbs
did the trick. I can now see the thumbnails. Now when I right click on one thumbnail I can select a video player and play the movie fine. However if I left click on a video I get an error message from the built-in video player?
Is there any additional package to add in order to use the built-in media player for AVCHD Lite movies?
Thanks again.

[SOLVED] Nautilus video thumbnails

Hi everyone! I want to generate video thumbnails with ffmpegthumbnailer in nautilus. I know i can do it by setting a command in the /gnome/thumbnailer section of gconf but i dont have keys for video thumbnails. There is only keys for fonts. Is there any way to add those video keys?
I done this once in ubuntu but now i dont want to install totem.
Thanks.

For movies I use the imdb-thumbnailer tool (it's in AUR). If I look in the source for the code that registers the thumbnailer, I find this:
for i in $video_extensions; do
gconftool-2 -s "/desktop/gnome/thumbnailers/$i"/command -t string '$THUMBNAIL_COMMAND
gconftool-2 -s "/desktop/gnome/thumbnailers/$i"/enable -t boolean 'true'
done
Search google for the thumbnail command and google for the list of extensions.
Good luck!

Black video thumbnails in iPhoto (Mavericks)

Hello everyone.
I have Mavericks on a late 2012 Macbook Pro running iPhoto 9.5.1.
I recently noticed that rough a third of my videos were displaying thumbnails that are just black. I freaked for a second, thinking the movie files were gone or something but thankfull the video files are still there and play just fine.
Still it would be nice to see that the video thumbnail images are rather than just black rectangles, right?
I tried all the different iPhoto rebuilding options (which takes a heckuva long time! ... then purchased iPhoto Library Manager and attempted some rebuild options using that with no luck.
Wondering if anyone has had this issue too and/or solved it?
Cheers!

Thanks for the quick reply!
I triple checked a handful of the video files and they aren't exhibiting black at the start.
How I checked:
- Select black video thumbnail image
- Press space bar (to "zoom" and begin playing video"
- Stop video playback at approx. five seconds in (video counter reads 00:00:05)
- Rewind "playhead" to very start of video so that the counter reads 00:00:00 and there is definately an image / content being displayed (e.g. is not black)
See attached screen shot with playhead at 00:00:00

No iPhoto Video Thumbnails in iMovie

Hi Guys,
I have a problem with generated iPhoto-Video-Thumbnails in iMovie .
It seems that iMovie is not able to create Video-Thumbnails out of iPhoto-Videos, if iPhoto-contents (pictures and videos) are stored outside of iPhoto Library.
If I allow iPhoto to copy pictures and videos into iPhoto library (during import), iMovie is able to generate those Video-Thumbnails from iPhoto-Videos.
Is there any kind of workaround to solve this problem.
I'm not willing to copy my iPhoto-stuff into iPhoto library due to the new iPhoto folder-structure, which is used since iPhoto 11.
Many thanks in advance of some helping hands...

Did you ever find a solution to this problem?

Missing Video thumbnails in iphoto in iphoto 11

I have just discovered lots of missing movies in my iphoto library, I have re imported them from an iphoto backup, and if i search for the keyword movie they appear, but no thumbnails appear in the photo display. I have tried rebuilding the library but none of the imported videos show up. New videos imported from my camera show up fine.

How can I delete the iPhoto Video Thumbnails in iMovie?

It's been a while since I've used iMovie, and when I opened the application tonight, I got the following message:
"iMovie needs to generate thumbnails for the videos in your iPhoto library. This process may take several minutes.
You can postpone this operation by clicking Later, but your iPhoto videos will be unavailable until the next time you restart iMovie."
I accidentally hit NOW, and the process began. When I realized it had used about 5 GBs of space, I force quit iMovie, but the disk space was not reclaimed. I need this space back now... I can import the iPhoto videos later. How can I undo the generated iPhoto video thumbnails? There was no project generated, and so no folder with the thumbnails in them. Where are they located? I would like to delete the iPhoto video thumbnails within iMovie, but preserve the thumbnails for other projects. And of course I would like to be sure that I keep the videos themselves in iPhoto - I definitely do not want to lose the videos there. Thanks for your help.

The latest incarnation of iMovie doesn't offer the 'Export with Quicktime'-options, the previous versions did.

Video thumbnails scrambled, won't playback (v3.4.3)

My video thumbnails in Aperture (version 3.4.3) are scrambled. Sometimes I can see part of a reference thumbnail frame (often in monochrome or with a single color overlay, like green), sometimes it's just all snow.
1) I just restored my mac mini from a time machine backup.
2) I also just imported an iPhoto library
If I browse to a pre-existing (before Time Machine restore) Aperture project, the correct thumbnail appears briefly before changing to the scrambled version.
When I select the video for playback all I get is a blank Viewer window (not video content, no controls, no playback).
If I browse to the source file via finder the video thumbnail displays and the video plays back correctly.
I have tried:
1) verifying and repairing disk permissions
2) repairing Aperture permissions
3) repairing the Aperture database
4) rebuilding the Aperture database
5) regenerating thumbnails (select video Photos->Regenerate Thumbnails) (thumbnail changes, still scrambled)
I don't use Aperture often so I'm not 100% sure when this started, but it seems to be after this current restore as supported by the brief correct appearance of old video thumbnails before they update to the scrambled version.
OS X 10.8.2
Aperture 3.4.3
Example of affected video:
IMG_0002.MOV
QuickTime movie
5MB
640x480
Duration: 00:11
Capture Source: iPhone 3GS

I suggest to check the video codecs you have installled; if you use Perian or have a flip-camera, you may have an incompatible video codec installed, see: http://support.apple.com/kb/TS4155
Why was a TimeMachine restore necessary? And did you use any helper/uninstaller/cleaner utilities, before you made the backup or after restoring? Sometimes this kind of helpers remove too much. I this case you may need to reinstall Mt. Lion to restore missing system components, that are not included in your TimeMachine backup.
Have a look at this thread Re: Import video to Aperture library on Mountain Lion,
and also at the post: Re: Import video to Aperture library on Mountain Lion in the same thread.
To reinstall from the "Recovery partition" see Linc Davis's post here: Re: Garageband doesn't open in Mac Mini mid 2011

How to create a video thumbnail???

I'm pretty new to FCP but I've just finished several shorts and I'm getting ready to upload them to my web site and other video sites. I would like a specific frame to appear as the video thumbnail. (In other words: the "preview frame" that appears in the player when it's not playing).
No one in my periphery seems to know how to do this.
Most video sites give you their choices of frames you can use. For instance YouTube gives you three options but chances are none will be the frame you want.
I would like to select the specific frame I want, regardless of where I upload it.
Has anyone had experience with this?

I would like to select the specific frame I want, regardless of where I upload it.
That's not going to work. The frames available on YouTube are set to specific times in the video.
Other services such as Vimeo might use a different timing or a different system altogether.
QuickTime compatible media can take advantage of the Set Poster Frame function and it can be any frame that you choose. Once the clip is outside the QuickTime environment, you take your chances with what's on offer.
The only way you can have any control over this is to set the poster frame in a QuickTime movie and host it on a compatible site such as MobileMe for example.

Video Thumbnail images gone - iPad 1st gen, iOS5

After updgrading my iPad 1st gen to iOS5, all of my video thumbnail images are gone.
The iPad just displays a white box with a gray flat screen TV icon for every video file listed under Movies or TV Shows
This is most troublesome when I touch the TV Shows button and I get a page full of those white boxes with the TV icon - and, as has always been the case, there is no name for the TV show. So I'm lost in the white boxes trying to find LOST the TV show.
Any thoughts on how I get my thumbnails back?

If they are in your iTunes library on your computer why don't you try syncing again. Make sure that all of the shows are selected to sync along with the sync Movies heading and then sync again.
If they are only on the iPad it might be a good idea to transfer the purchases into the iTunes library. Connect the iPad to the computer, launch iTunes and right click on the device name and select Transfer Purchases.
If you have tried syncing, try restarting, resetting and quitting the videos app.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
To quit the videos app - Go to the home screen first by tapping the home button. Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner to close the apps. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.

Video thumbnails won't display in organizer (win 7)

after importing jpegs & mpegs into premier 8 the pics display as thumbnails but the videos do not. Instead just a film strip icon with the name of the video. the video wont play in the organizer. However video thumbnails display & play if I open them in a project. strange???!

With your MPEGs, it depends on how your system is set up and if they are compatible.
But, with JPEGs, the thumbnails simply may not have been generated yet. It takes a while (depending on how much media you have on your computer and how fast your computer is) for the Organizer to build your initial catalog and generate all of the thumbnails. Be patient. Each time you turn your Organizer on, it's working. Eventually they'll show up -- and then they'll be there for as long as you keep your catalog.
NOTE: The exception is if you are running the 64-bit version of Windows 7, which is not yet fully compatible with this program.
