# This example demonstrates the use of a Multi-Image Sink to encode and
# save video frames to JPEG files at specified dimensions and frame-rate.
#
# The ouput file path/names are specified using a printf style %d in the
# provided absolute or relative path.
# eample: "./my_images/image.%d04.jpg", will create files in "./my_images/"
# named "image.0000.jpg", "image.0001.jpg", "image.0002.jpg" etc.
#
# You can limit the number of files that are saved on disc by calling
# dsl_sink_multi_image_file_max_set. Default = 0 = no max.
#
# Once max-files is reached, old files will be deleted to make room for new
# ones.
