Pipefile Usage
The following sections describe the blocks needed to use this process in a pipe file.
Pipefile block
# ================================================================
process <this-proc>
:: frame_list_input
# Inter frame time in seconds. The generated timestamps will have the specified
# number of seconds in the generated timestamps for sequential frames. This can
# be used to simulate a frame rate in a video stream application.
frame_time = 0.03333333
# Name of file that contains list of image file names. Each line in the file
# specifies the name of a single image file.
image_list_file = <value>
# Algorithm configuration subblock
image_reader = <value>
# Path to search for image file. The format is the same as the standard path
# specification, a set of directories separated by a colon (':')
path = <value>
# ================================================================
