YUV4MPEG2 - video stream format used by pipe-based MJPEGtools

yuv4mpeg(5) MJPEG Tools Manual yuv4mpeg(5)

NAME
YUV4MPEG2 - video stream format used by pipe-based MJPEGtools

DESCRIPTION
Many of the MJPEGtools communicate via pipes and act as filters (or
sources or sinks). The format of video data used in the pipes is
referred to as "YUV4MPEG", or, more precisely, "YUV4MPEG2". (The for‐
mat was extended and codified during v1.5.x of the tools.)

The basic structure is a stream header followed by an unlimited number
of frames.

yuv2lav - encodes lavtool's raw YUV frame streams into MJPEG files

yuv2lav(1) MJPEG tools manual yuv2lav(1)

NAME
yuv2lav - encodes lavtool's raw YUV frame streams into MJPEG files

SYNOPSIS
yuv2lav [-f a|A|q|m] [-q num] [-b num] [-I num] [-m num] [-v num] [-w
file] -o output-file

DESCRIPTION
yuv2lav is a simple MJPEG encoder for raw YUV frame streams as they are
emitted by lav2yuv(1) or lavpipe(1), for example.

yuvycsnoise - Noise filter specialized for NTSC Y/C separation noise

yuvycsnoise(1) MJPEG tools manual yuvycsnoise(1)

NAME
yuvycsnoise - Noise filter specialized for NTSC Y/C separation noise

SYNOPSIS
yuvycsnoise [-t] [-m t|b|i|c] [-S MIN] [-T ERRT[,MAXT]] [-B
ERRB[,MAXB]] [-I ERRI[,MAXI]] [-C ERRC[,MAXC]]

DESCRIPTION
If video capture hardware has only a poor Y/C separator, at vertical
stripe (especially red/blue), noises appear which seem checker flag and
bright/dark invert per 1 frame.

yuvtoppm - convert Abekas YUV bytes into a portable pixmap

yuvtoppm(1) yuvtoppm(1)

NAME
yuvtoppm - convert Abekas YUV bytes into a portable pixmap

SYNOPSIS
yuvtoppm width height [imagedata]

DESCRIPTION
Reads raw Abekas YUV bytes as input. Produces a portable pixmap as
output. The input file is just YUV bytes. You have to specify the
width and height on the command line, since the program obviously can't
get them from the file.

English

yuvsplittoppm - convert a Y- and a U- and a V-file into a portable pixmap

yuvsplittoppm(1) yuvsplittoppm(1)

NAME
yuvsplittoppm - convert a Y- and a U- and a V-file into a portable
pixmap

SYNOPSIS
yuvsplittoppm basename width height [-ccir601]

DESCRIPTION
Reads three files, containing the YUV components, as input. These
files are basename.Y, basename.U, and basename.V.

yuvscaler - UPscales or DOWNscales a YUV4MPEG2 stream to a specified format

yuvscaler(1) MJPEG tools manual yuvscaler(1)

NAME
yuvscaler - UPscales or DOWNscales a YUV4MPEG2 stream to a specified
format

SYNOPSIS
yuvscaler [-I input_keyword] [-M mode_keyword] [-O output_keyword]
[-n p|s|n] [-v 0-2] [-h]

DESCRIPTION
yuvscaler is a general (UP or DOWN) scaling utility that is provided to
allow conversion between different video formats. It reads in a
YUV4MPEG2 format stream from stdin (such as that produced by lav2yuv)
and outputs such stream to stdout (e.g.

English

yuvplay - Display YUV4MPEG2 streams (using SDL)

yuvplay(1) MJPEG tools manual yuvplay(1)

NAME
yuvplay - Display YUV4MPEG2 streams (using SDL)

SYNOPSIS
yuvplay [options]

DESCRIPTION
yuvplay produces on-screen playback of a YUV4MPEG2 stream which is pro‐
vided to stdin, typically through piping from the stdout of lavpipe(1),
lav2yuv(1), mpeg2dec(1) or a similar program. It should be noted that
for pure playback lavplay should be a superior option.

yuvmedianfilter - A filter for yuv images produced by the mjpeg tools

yuvmedianfilter(1) MJPEG tools manual yuvmedianfilter(1)

NAME
yuvmedianfilter - A filter for yuv images produced by the mjpeg tools

SYNOPSIS
yuvmedianfilter [-r num] [-R num] [-t num] [-T num] [-I num] [-f] [-w
num] [-s num] [-v num] [-h]

DESCRIPTION
yuvmedianfilter is designed to enhance/filter images. It takes the
input from STDIN and writes output to STDOUT.
This filter looks around the current point for a radius and averages
the values that fall inside a threshold.

yuvkineco - revert 2-3 pulldown movie

yuvkineco(1) MJPEG tools manual yuvkineco(1)

NAME
yuvkineco - revert 2-3 pulldown movie

SYNOPSIS
yuvkineco [options] [-C PATH]
yuvkineco [options] -O|N PATH

DESCRIPTION
yuvkineco reverts to original non-interlaced frames, from NTSC video
which was film sourced and 2-3 pulled down. Input fps code must be
4(29.97fps), output fps code can be selected from 1(23.97fps) to
4(29.97fps). If 2, 3 or 4 selected, duplicated frames remain but they
are reverted to non-interlaced.
