oggSplit - demultiplexes ogv files
SYNOPSIS
oggSplit outfile.ogv
DESCRIPTION
oggSplit demultiplexes a multiplexed ogg file into several files with one stream each.
An ogg video file (with extension .ogv) usually consist of an audio and a video stream. The command line tool oggSplit disjoins these
streams into seperate files. This is also often called demultiplexing.
After that you have all embedded files of this input file with the following naming:
theora_<ID>.ogv: This is the video stream encoded with the theora codec. The <ID> is the stream ID that is created by the encoder to
uniquely identify this stream.
vorbis_<ID>.oga: This is the audio stream encoded with the vorbis codec. The <ID> is the stream ID that is created by the encoder to
uniquely identify this stream.
unknown_<ID>.ogv: This is an unknown stream, that could not be interpreted.The <ID> is the stream ID that is created by the encoder to
uniquely identify this stream.
All files are fully playable with your favoured video or audio player (except the streams, that are uninterpreted).

oggThumb - creates thumbnails from an ogg video file
SYNOPSIS
oggThumb [options] file1.ogv [ file2.ogv [ file3.ogv [...] ] ]
DESCRIPTION
oggThumb creates Thumbnails from one or more ogg video files, at a given time position or a given frame number. It is also possible to cre-
ate 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 commas. 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 commas. The frame num-
bers 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 overwrit-
ten.
If the name has an extension. This extension is used to identify the output picture format.
Example: -n myNo_%_thumb
EXAMPLE
oggThumb -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 mysecondfile.ogv
