video thumbnail help

[COKEDUDE]

How do you make video thumbnails like this in Linux? The only program I know of that can do this is Media Player Classic. I hope there is a way to do this in Linux. What would these types of thumbnails be called?

in synaptic.
search: video thumbnail

Surely one of the results should be useful.

Hi,

You can try to run MPC in wine, good if it's working

you could try the script on this page

http://minhtech.com/linux/fedora-linux- ... rl-script/

for flv format change the format from mp4 on line 12 and make the script executable.

needs mplayer, ffmpeg and imagemagick all in the repo.

modified script is here:

Code: Select all

#!/usr/bin/perl -w

use strict;
use POSIX;

my $dir = getcwd();
my ($width, $height, $length);

opendir(DIR, $dir) or die $!;

while (my $file = readdir(DIR)) {
   next unless ($file =~ m/\.flv$/);

   my @info = `mplayer -benchmark -nosound -quiet -vo null -frames 1 -identify $file`;

   foreach (@info) {
      if (substr($_, 0, 15) eq "ID_VIDEO_WIDTH=") {
         $width = substr($_, 15);
      }
      elsif (substr($_, 0, 16) eq "ID_VIDEO_HEIGHT=") {
         $height = substr($_, 16);
      }
   elsif (substr($_, 0, 10) eq "ID_LENGTH=") {
         $length = substr($_, 10);
      }
   }

   $width = floor($width / 3);
   $height = floor($height / 3);
   my ($tile_x, $tile_y, $frame) = (6, 4, 1);
   my ($position, $files);

   while ($frame < ($tile_x * $tile_y + 1)) {
      $position = $frame * floor($length / ($tile_x * $tile_y));

      system("ffmpeg -ss $position -i $file -vcodec mjpeg -vframes 1 -s $width"."x"."$height -an -f rawvideo -y __$frame.jpg 2> /dev/null");

      $files = $files . " __$frame.jpg";

      $frame += 1;
   }

   system("montage -title \"$file\" -geometry $width"."x"."$height"."+"."1"."+"."1 -tile $tile_x"."x"."$tile_y$files $file.jpg");

   system("rm __*.jpg");
}

closedir(DIR);

put the script and your <filename>.flv file into home, open a terminal then run
./thumbs.pl
and it will make a jpg <filename>.flv.jpg

using the only flv file (a tv advert, what else!) I have, the output is:
http://www.imageno.com/8t8zvnp88o40pic.html

always seems to produce 6 wide x 4 deep but the script is probably tweakable.

I don't wanna use wine . I have no interest in opening myself up for viruses.

Thank you rich2005. I will test that out shortly.

I have searched various sites and found these 4 programs for creating thumbnails.

totem, gframecatcher, videocut, smplayer

gframecatcher- Untested
http://developer.berlios.de/projects/gframecatcher/

videocut- This has problems mp4's and mov's. The only type of video I have been able to make thumnails of is avi's and wmv's.
File, open file, export

totem- I have had no problems with any type of video I have tried. I tried avi, wmv, mp4, and mov.
Edit, Create screenshot gallery, save

smplayer- smplayer has the most features so if you like features I recommend using smplayer. I have had no problems with any type of video I have tried. I tried avi, wmv, mp4, and mov.
Video, Preview, ok, save
