.TH "rawdv2yuv" 1
|
|
.SH NAME
|
|
rawdv2yuv decodes a rawdv stream from stdin to yuv I420/YV12 and
|
|
writes it to stdout.
|
|
.SH SYNOPSIS
|
|
.B rawdv2yuv [options]
|
|
.SH DESCRIPTION
|
|
.B rawdv2yuv
|
|
rawdv2yuv is a simple I420/YV12 encoder that has some additional
|
|
parameters to produce a half sized I420/YV12 frame. The motivation
|
|
for this option is to be able to quickly downscale a full PAL/NTSC
|
|
frame.
|
|
|
|
This program expects input from STDIN and writes a Y4M stream
|
|
to STDOUT.
|
|
|
|
.SH OPTIONS
|
|
The command line options allow to specify its behaviour
|
|
.TP
|
|
.B \-x
|
|
Swap cb/cr channels to produce IV12 (default is I420)
|
|
.TP
|
|
.B \-n [01]
|
|
Norm to use for rawdv input, 0 = NTSC , 1 = PAL (default is PAL)
|
|
.TP
|
|
.B \-h
|
|
Output half sized YV12/I420 frame (default is no downscaling)
|
|
.TP
|
|
.B \-c <num>
|
|
Clip width by a multiple of 8
|
|
.TP
|
|
.B \-q
|
|
Set rawdv quality to FASTEST (monochrome). Default is BEST.
|
|
.TP
|
|
.B \-v [012]
|
|
Try to be silent or verbose
|
|
.SH USEFULL EXAMPLES
|
|
.TP
|
|
.B dvgrab --format rawdv - |rawdv2yuv -h -c 8 | yuvplay
|
|
This commands grabs rawdv and pipes it trough rawdv2yuv
|
|
to produce a 352x288 y4m stream. Full PAL is 720x576,
|
|
the -h option produces 360x288 and -c clips off 8 pixels
|
|
from the frame width.
|
|
.TP
|
|
.B cat rawdv_file.dv | rawdv2yuv -n 1 > i420_stream.y4m
|
|
Converts a NTSC rawdv file to a 720x480 y4m frame (I420)
