VMPEGTOVX

VisionX V4

NAME

vmpegtovx − convert mpeg video to VX image sequence

SYNOPSIS

vmpegtovx [if=<infile>] [of=<output-file]

DESCRIPTION

vmpegtovx is a program to convert a video file to a VisionX image sequence. It uses ffmpeg to decode the video and will exit if the decoder is not found. The user should specify the number of frames to convert (n=) or specify the frame range to convert (f=). By default, the video is converted from the beginning, but the user may choose to start the conversion

in the middle of the video using st= parameter.

Block conversion is also possible for separating a large image sequence into smaller files. Each block will contain the number of frames specified by b= parameter and be named sequentially (<of>.<n>.vx), starting at n=1.

CONSTRAINTS

Output image will be in byte format.

OPTIONS

	if=		input file, mpeg video
	of=		output file, VisionX image sequence
	n=		number of frames to convert (default 10)
	f=<f1,fn>		specific frame range to convert (default 1,10)
	st=		time to skip before converting (hr:mn:sc) default 00:00:00
	b=		number of frames to convert in a block (each block is output as <of>.<n>.vx
	-t		compute a tiff stack rather than VX output
	-g		convert color images to gray only output
