ImageThe Next ESA SAR Toolbox (NEST) is used forreading, post-processing, analyzing, andvisualizing the large archive of data from ESA SARmissions, including ERS-1 and 2 and ENVISAT. NESThas been built using the Basic ERS and Envisat(A)ATSR and MERIS (BEAM) Toolbox and it covers thefunctionality of the older Basic Envisat SARToolbox (BEST).License: GNU General Public License (GPL)Changes:

lav2yuv

lav2yuv(1)							MJPEG tools manual							lav2yuv(1)

NAME

       lav2yuv - Convert a MJPEG file to raw yuv

SYNOPSIS

       lav2yuv [options] lavfile1 [lavfile2 ... lavfileN]

DESCRIPTION

       lav2yuv	converts  an  MJPEG  video sequence described by a sequence of MJPEG video files and/or edit lists pointing to such files into the
       simple uncompressed planar 4:2:0 Y'CbCr format, as used by mpeg2enc(1) MPEG encoder and	image  processing  filters  like  yuvscaler(1)	or
       yuv2dfilter(1) or yuvdenoise(1).

       Output is to stdout so that by piping the output of lav2yuv into a suitable pipeline it is possible to process and then encode or play back
       video recorded in any of the mjpegtools MJPEG container formats: AVI, quicktime or edit lists describing editted versions of video held	in
       such files.

       Mixing different files with different video formats is currently not possible.

       The -S -T -D options are used for scene detection which is used by linux video studio.

OPTIONS

       lav2yuv accepts the following options:

       -m   Force mono-chrome

       -c   Conceal frames containing corrupt MJPEG data by repeating the preceeding good frame.

       -S list.el
	    Output a scene list with scene detection

       -T num
	    Set scene detection threshold to num (default: 4)

       -D num
	    Width decimation to use for scene detection (default: 2)

       -o num
	    Frame offset - skip num frames at the beginning.  if num is negative all but the last num frames are skipped

       -f num
	    Only num frames are written to stdout. 0 means that all frames are processed.

       -A width:height
	    Set/override  the  sample  aspect  ratio  (SAR)  emitted in the output stream header.  Currently, the SAR is only auto-detected for DV
	    files, and guessed otherwise.

       -P width:height
	    Set the intended/approximate display aspect ratio (DAR) for the stream.  This value is only used to guess the SAR when  it	cannot	be
	    detected  from  the  input	stream.   The default DAR is '4:3' (corresponding to a standard TV screen); another useful value is '16:9'
	    (corresponding to widescreen TV).

       -C chroma
	    Set output chroma (default: '420jpeg').  Currently, '420jpeg', '420mpeg2', '420paldv', '422' are available.

       -x   Exchange fields.  Useful if the field order was reversed during editing.
