NAME

6       oggThumb - creates thumbnails from an ogg video file
7

SYNOPSIS

9       oggThumb [options] file1.ogv [ file2.ogv [ file3.ogv [...] ] ]
10

DESCRIPTION

12       oggThumb  creates  Thumbnails  from  one  or more ogg video files, at a
13       given time position or a given frame number. It  is  also  possible  to
14       create a series of thumbnails at different time or frame positions. The
15       pictures can be created in JPG or PNG format and can be resized to  any
16       given size.
17
18       The naming of each thumbnail series follows the following rule:
19
20       <filename_without_extension>_x.<picture_extension>
21
22       Where  x starts with 0 and is incremented with every created thumbnail.
23       So the thumbnails are successivly numbered  by  the  appearence  order.
24       This is even valid, if time positions and frame numbers are mixed.
25

OPTIONS

27       -t     Time  at  which  a  thumbnail  should  be created. More than one
28              thumbnail time can be concatenated by komas. The  times  can  be
29              set  by integer or floating point values in seconds. If the time
30              is not exactly matching, the next frame is used. The times don't
31              have to be sorted incrementally.
32
33              Example: -t 12.4,14.157,13.23
34
35
36       -f     Number  of  a  frame that should be created as a thumbnail. More
37              than one thumbnail frame can be concatenated by komas. The frame
38              numbers  must be an integers. The frame numbers don't have to be
39              sorted incrementally.
40
41              Example: -f 12000,13000,11000
42
43
44       -s     Picture output size. The thumbnail is created in the size  given
45              as <width>x<height>.  If you want to include the thumbnails into
46              your webpage and you need to have  a  fixed  width  but  dynamic
47              height,  you  can set the dynamic axis to 0. So the aspect ratio
48              of the video frame is kept. This is the same for  setting  width
49              or height to 0.
50
51              Example: -s 0x100
52
53
54       -o     Output format. This can be png or jpg. The default is jpg.
55
56              Example: -o png
