I have ubuntu 9.04x64 edition.i have installed gstreamer0.10-plugins-bad,gstreamer0.10-plugins-ugly,gstreamer0.10-ffmpeg so all video & audio files are played by totem.But why there is no thumbnail for flv files though in nautilus preview I have set always & file size upto 4GB.

The player that is making the thumbnails for you does not have the necessary .flv codec.

You might need to transcode the .flv's into something more universal to your system before you'll see them as thumbnails in your application.

I know that linux OS play oga(audio) & ogv(video) by default.Also show their preview.I want to ask 'Is there a way so that I can see thumbnail for flv file in my file manager'

i am using ubuntu 9.04.
So I installed ffmpegthumbnailer.
In order to verify its working I ran
$ffmpegthumbnailer -i ed.flv -o ed.png
It worked & gave 128x72 png image.
I read from http://code.google.com/p/ffmpegthumbnailer/wiki/Faq about using ffmpegthumbnailer.
so i ran gconf-editor
and edited desktop/gnome/thumbnailers/video@x-flv
and edited value of string 'command' to "/usr/bin/ffmpegthumbnailer -s %s -i %i -o %o -c png -f -t 10"(without double quotes).
Still thumbnail not visible.
Can anybody suggest ?

I FOUND OUT SOLUTION
For all GNOME users who use nautilus but no thumbnail for .flv files.
I had installed ffmpegthumbnailer (version:1.3.0-1) using
#apt-get install ffmpegthumbnailer

For flv video.Run
$gconf-editor
Edit string of /desktop/gnome/thumbnailers/video@x-flv/command to
"/usr/bin/ffmpegthumbnailer -s %s -i %i -o %o -f -t 25"(without double quotes).
I have noticed that avi files are supported by gnome-video-thumbnailer so ffmpegthumbnailer was not used in ubuntu 9.04 64bit edition no matter whatever I try.

i reached the developer who replied(so nice of him) to use ffmpegthumbnailer 1.5.6 on ubuntu 9.10 and consult http://code.google.com/p/ffmpegthumbnailer/wiki/Faq.

NOTE:string I have mentioned above is slightly different(but worked well) than mentioned on wiki.

I have a question
For some video files I found out their thumbnail images in ~/.thumbnails/normal then replaced those images with what I like & now I have nice images for thumbnails .I know that whenever thumbnail cache will be cleared then thumbnails will be regenerated.

I think there should be a file which contains list of video files & corresponding thumb png.Can I edit that so that the names of thumbnail images are simple unlike 'd4e97b3134d584ead60ce5f42f3c4703.png'

Hi,

there is an easier solution.

You only have to install the totem codec and refresh thumbnails.

Code:

sudo apt-get install gstreamer0.10-ffmpeg
find ~/.thumbnails/ -name "*.png" -exec rm -f {} \;

And then everything goes right...

Actually I am running ubuntu 8.04-GNOME (regularly updated) but totem in this could not play flv files (also no thumbnails by nautilus though ffmpegthumbnailer helps) I got from youtube giving internal data stream error (maybe due to latest h264,aac encoding).
Mplayer , ffplay from medibuntu also did not but those compiled from tarball did.
Option I had was to upgrade totem (changing repository brought inconsistency in library) or ubuntu (I will keep hardy till april 2011 or more).
