OGGTHUMB(1) User Manuals OGGTHUMB(1)NAMEoggThumb - creates thumbnails from an ogg video file
SYNOPSISoggThumb [options] file1.ogv [ file2.ogv [ file3.ogv [...] ] ]
DESCRIPTIONoggThumb creates Thumbnails from one or more ogg video files, at a
given time position or a given frame number. It is also possible to
create a series of thumbnails at different time or frame positions. The
pictures can be created in JPG or PNG format and can be resized to any
given size.
The default naming of each thumbnail series follows the following rule:
<filename_without_extension>_x.<picture_extension>
Where x starts with 0 and is incremented with every created thumbnail.
So the thumbnails are successivly numbered by the appearence order.
This is even valid, if time positions and frame numbers are mixed.
OPTIONS-t Time at which a thumbnail should be created. More than one
thumbnail time can be concatenated by komas. The times can be
set by integer or floating point values in seconds. If the time
is not exactly matching, the next frame is used. The times don't
have to be sorted incrementally.
Example: -t 12.4,14.157,13.23
-f Number of a frame that should be created as a thumbnail. More
than one thumbnail frame can be concatenated by komas. The frame
numbers must be an integers. The frame numbers don't have to be
sorted incrementally.
Example: -f 12000,13000,11000
-s Picture output size. The thumbnail is created in the size given
as <width>x<height>. If you want to include the thumbnails into
your webpage and you need to have a fixed width but dynamic
height, you can set the dynamic axis to 0. So the aspect ratio
of the video frame is kept. This is the same for setting width
or height to 0.
Example: -s 0x100
-o Output format. This can be png or jpg. The default is jpg.
Example: -o png
-n Alternative thumbnail picture name. The % can be used within the
name to indicate the counter placeholder.
In case of more than one video file, the counter continuous
throughout the different videos, so that the pictures are not
overwritten.
If the name has an extension. This extension is used to identify
the output picture format.
Example: -n myNo_%_thumb
EXAMPLEoggThumb-t 10.3,22.4,31.9,43.4,59.4 -f 1200 -s 0x100 myFile.ogv
oggThumb-f 200,400,300,100 -t 3.54 -n %_thumb.png myfile.ogv mysecondâ
