Software :: Preview / Thumbnail / Screenshot Generator Of A Video File
Feb 27, 2009
I have some videos I am looking to share and post to a couple of places. I am looking to preview to the potential downloaders the file quality, plus some statistical info. In Windows Media Players Classic, as shown in my example here, you have the length of the video, file size, file name... and in each frame preview you have a time stamp stating at what part of the video the from is from.is there a program in linux that can do this for me? That can generate the same (or maybe more) info automatically?

After I manually installed multimedia codecs, like w32codecall, I got Linux to play movies and I also got thumbnail previews of them in Dolphin. However, I noticed that recently Dolphin doesn't display my thumbnails anymore. I don't quite recall whether the any video player could use my installed codecs, at least xine works. The only thing that could have caused that is actually the automatic system updates I received. I still have my multimedia codecs installed, but Dolphin doesn't show the movie previews anymore.

I'm not too sure what causes this. But why do some video files display a thumbnail preview in Nautilus and others don't? See screenshot below.

How this can be done? I already have the necessary codecs installed and have kde 4.2.

At some point after one of the many updates I do to my system, I seem to have lost the ability to preview myself on cam. Simply put, software like CamStream and Cheese just give me a black screen when I open it up. So, I cant see how I look on cam and what's in or out of the shot. If I tell Cheese or Camstream to capture a still, there is no problem. In fact, that is the only way I can determine what the camera is seeing of me and my background.
The only "solution" is to either have Cheese takke my pic and determine from there (as just mentioned), or go on a video chat room and have it use my camera to give me a real-time look at what the camera is aimed to. As someone who creates webcam videos for upload, and sometimes needs to move the camera while still live, this is not convenient so I hope to fix it.
Here are the command line outputs Im getting:
Cheese:
Code:
** (cheese:3704): WARNING **: could not generate thumbnail for /home/lixen69y2k/Webcam/2010-08-25-101226.ogv (video/ogg)
** (cheese:3704): WARNING **: Icon 'video-ogg' not present in theme
Camstream:
Code:
W: CamStream version 0.27 starting.
>> void CCamStreamApp::ReadConfigFile()
<< void CCamStreamApp::ReadConfigFile()
code....
Could not grab image (select timeout): Resource temporarily unavailable.Seems that GUVCview gives me the best articulation of what the problem is. I have both a built-in webcam for my laptop as well as a USB one. Both seem to have this problem so I know its a case of some part of my software being the trouble.

Today i installed lucid and its working fine. But I have tones of .flv and .mp4 videos (from ..... ) which do not show a preview thumbnail when I have selected "Icon View" in Gnome. It shows the standard icon of a movie reel. Am I missing any settings? It used to work great in karmic.

I have this bkl-orbiter daemon running for something that apparently needs it (wacom drivers maybe).
It created a "bkl-thumbnail" home dir and has been caching image thumbnails.
Any way to keep it from doing that? Or find out why it's doing it?

I'm using Ubuntu 10.04 and my problem is with this one video the preview icon in nautilus will not load for me. It's encoded the same as the other 120 videos on the drive and plays just fine in totem. I copied the video from another drive and the preview icon for the video is present on it. Just seems like it's not even attempting to create a preview icon, is there a way of making it?

When I use any application to upload an image, the dialogue box opens for me to select my file, but I can't view my images as thumbnails. Instead it reverts to List view and displays the columns with the file name, last modified etc data. This is very frustrating when dealing with images. I'm a photographer and handle many hundreds of images.

I use Ubuntu Lucid Lynx 10.04, and usually I record my desktop with the program "Record my Desktop", the format of the video is: .ogg, when I had Ubuntu Karmic Koala, I recorded my screen then in kdenlive added audio and effects and all's right, but now i update to Lucid Lynx, and trying to edit my video in Kdenlive and I obtain this screen(I attached my screen), I noticed that the new video that I record after the upgrade of Ubuntu, I can't view the preview with Kdenlive, but with the old record, I can view the preview. And also i noticed that with pitivi, the new program to edit videos of Lucid Lynx, works fine, with new and old recordings, don't have problem.

I don't how long is has been happening for (I've just upgraded my old computer, so it is now my faster and better machinig), but Nautilus is failing to create thumbnails for anything other than text files.
I've swapped the settings around to try to trigger changes, but even on "Local only" or "Always" with a 10MB cap then Nautilus won't generate previews for anything other than text files. All images/videos/pdfs/web pages that should have thumbnails generated for them have the "pending" icon but never generate a thumbnail. If, however, I open the file (with Eye of Gnome or Gimp) and refresh the folder then the thumbnail appears for the one file I just opened (so I could go through and preview all images, but I'd really rather not!)
I've tried removing/renaming my .local/share/mime folder in case it was incorrectly handling file types, but that didn't help. I've looked in gconf at the thumbnailer apps, but that appears to be for everything except images. Running "evince-thumbnailer" on its own works fine as well and generates an image. There aren't any related errors in .xsession-errors, and I don't know where else Nautilus logs to (running "nautilus --browser" creates a browser window but then drops back to the command line and doesn't print any output).
I'm using openSUSE 11.2 and the default Gnome, with codecs from Packman. A fairly similar setup on my other machine is thumbnailing perfectly fine.

I want nautilus to use file preview or not depending on what the view is for that folder. I want file preview to be enabled if I am using icon view, and disabled if I am using list view. This way image folders will be previewed (because I have set such folders to icon view), and other folders wont be (because they default to list view). I also want the desktop to be always previewed.This seems like quite a simple and common-sense desire, but I cant find out anywhere how to do this. At the very least what I'd like is the ability for force preview for a folder if I want to investigate it more closely - even if I have to click a button of select something to do so.

We have recently upgraded to ubuntu 11.04 64bit from 10.04 and 10.10 in a networked office in which our home directories are mounted on a server raid array. Ubuntu considers that the home directory is a local drive rather than on a networkWe have noticed that file preview are very very slow in 11.04 for pdf's and pictures in nautilus, causing a lag of around 10 seconds for each file. This can cause a problem for folders which hold multiple files which can be previewed. Preview worked fine in previous versions of ubuntu on the same machine, with the same network setup. Previewing of actual local files works faster, but is slower on 11.04, than previous versions.
Both the 10.10 and 11.04 systems are up to date with available updates (11.04 - 2.32.2.1 and 2.30.1 on ubuntu 10)Obviously, there is a work around for this problem - turn off preview. But, it would be nice to turn it on as its a useful feature.

I am trying to emulate a .bat file I have on Windows. The script turns all the mp3 files into a m3u file.So far I have found the command "ls -1 >playlist.m3u *.mp3" this works great but what I want is to drag a file into the folder an album is in and then double click and it will run the command. I tried making a launcher and put that command on it, it seems to open up a terminal window but no playlist.m3u is generated. Could you tell me what I am doing wrong?
