Generic Decoders
Some of the decoders built in to SiraView are known as “Generic” decoders: GenericADV601,
Generic Folder Of JPEGs and Generic JPEG.
These decoders only know how to decode
images – they cannot decode timestamp or
camera number information. If you load a file
using a generic decoder, you will be able to see
the video frames, but playback speed will be
wrong, timestamps won’t exist, and all
channels (if it’s a multichannel video) will be
displayed multiplexed in the same window.
It is not recommended that you use generic
decoders for normal situations, however they have been included in
SiraView as they might enable you to get some useful information
should all else fail.
Because of these limitations, generic decoders are excluded from the
autodetect mechanism; to use one you must explicitly select it.
To open a file use the File -> Open video menu option, and select the
appropriate file from the hard disk, USB device or CD/DVD.
Then expand the “Files of type” drop-down menu and select the
generic decoder you wish to use. SiraView will then examine the file
or images compatible with the selected decoder. This is an
exhaustive search of the file and may take a long time.
