NAME    [Toc]    [Back]

     memtovid -	Video Library single frame output tool

SYNOPSIS    [Toc]    [Back]

     memtovid -f <filename> [-h] [-o <output>] [-v <memnode>] [-n <num>]
		    [-F] [-c] [-t] [-p]	[-P] [-I] [-m <format>]
		    [-r	[packing]]

PARAMETERS    [Toc]    [Back]

     -f	<filename>
	  Name of input	file containing	image data.

     -h	  Display a usage message

     -o	<output>
	  The node number of the video drain node you wish to use.

     -v	<memnode>
	  The node number of the memory	source node you	wish to	use.

     -n	<num>
	  Number of images to be read in from disk and sent to video output.

     -F	  Use filter when converting rgb to yuv

     -c	  Center image in video	output.

     -t	  Wait for external trigger before sending image to video output.

     -p	  Pause	for user response after	sending	each image to output.

     -P	  Pause	for user response after	all images have	been output.

     -I	  Print	node and path IDs for use with command line interface.

     -m	<format>
	  Select format	used to	display	the image.

     -r	[packing]
	  Selects raw input mode. The specified	packing	number will be used to
	  display the image.

DESCRIPTION    [Toc]    [Back]

     The application memtovid, on hardware that	supports the memory to video
     path, writes the image to the node	specified by the -o option.  If	-o is
     not specified, the	image is sent to output	node number 0.

     memtovid takes an image in	any of the formats produced by running
     vidtomem, the single frame	capture	tool.

     This image	is in device-dependent format (see applicable release notes on
     specific products for more	info on	these formats.)

     The -c option centers the image in	the video output signal	when using
     images that are smaller than the video format.

     The -p option pauses memtovid after each image is sent to the video
     output until the user presses a key. If -p	is not specified memtovid
     sends successive images to	video out with no pauses in between.

     Specifying	the -P option causes memtovid to pause only after all frames
     have been output.	There is no benefit gained in using this option	in
     addition to the -p	option.

     The -I option prints the node and path IDs	on stdout. These are required
     when using	the command line interface tool, vlcmd , to get	or set
     controls on the video hardware.

     The -r option specifies the packing of the	input file.  If	-r is not
     specified,	memtovid will attempt to determine the appropriate packing
     based on the input	file's extension. The filenames	produced by with
     vidtomem command are compatible with memtovid. See	/usr/include/vl/vl.h
     for specific numbers.

     The -m option specifies the format. By default, VL_FORMAT_SMPTE_YUV is
     used.  See	VL_FORMAT_* in /usr/include/vl/vl.h for	specific numbers.

     The -v and	-o options may be used to specify the source and drain node
     numbers explicitely. For instance,	the following instructs	memtovid to
     use video node 2 and memory node 1:

	  memtovid -v 1	-o 2 -f	image-00000.rgb

     Note: all combinations of video and memory	nodes may not be possible.
     Consult the Owner's Guide or Programmer's Guide for a list	of node
     numbers for each device.

NOTES    [Toc]    [Back]

     When neither the -P nor -p	option is not specified, then memtovid waits
     for a VLStreamStopped event to occur.  Not	all video products currently
     support this event.  This is the case for both Galileo and	Indigo2	Video.
     Simply interrupt the program to terminate it.

     Some devices, such	as IMPACT Video, do not	contain	a frame	buffer to hold
     the frame after it	has been played. Consequently, if the -p option	is not
     used, the image will be output for	only one frame duration. If the	-p
     option is used, then the frame will be output continuously.
