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 default 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.

OPTIONS

28       -t     Time  at  which  a  thumbnail  should  be created. More than one
29              thumbnail time can be concatenated by komas. The  times  can  be
30              set  by integer or floating point values in seconds. If the time
31              is not exactly matching, the next frame is used. The times don't
32              have to be sorted incrementally.
33
34              Example: -t 12.4,14.157,13.23
35
36
37       -f     Number  of  a  frame that should be created as a thumbnail. More
38              than one thumbnail frame can be concatenated by komas. The frame
39              numbers  must be an integers. The frame numbers don't have to be
40              sorted incrementally.
41
42              Example: -f 12000,13000,11000
43
44
45       -s     Picture output size. The thumbnail is created in the size  given
46              as <width>x<height>.  If you want to include the thumbnails into
47              your webpage and you need to have  a  fixed  width  but  dynamic
48              height,  you  can set the dynamic axis to 0. So the aspect ratio
49              of the video frame is kept. This is the same for  setting  width
50              or height to 0.
51
52              Example: -s 0x100
53
54
55       -o     Output format. This can be png or jpg. The default is jpg.
56
57              Example: -o png
58
59
60       -n     Alternative thumbnail picture name. The % can be used within the
61              name to indicate the counter placeholder.
62
63              In case of more than one  video  file,  the  counter  continuous
64              throughout  the  different  videos, so that the pictures are not
65              overwritten.
66
67              If the name has an extension. This extension is used to identify
68              the output picture format.
