NAME y4munsharp – Unsharp filter for YUV4MPEG2 streams SYNOPSIS y4munsharp [options] DESCRIPTION y4munsharp is an implementation of the GIMP unsharp filter for YUV4MPEG2 streams. The usual 3 parameters for unshap mask processing (radius, amount and threshold) are specified on the command line. By default only the Y’ (luma) component is processed although processing of the…
NAME y4mtoppm – Convert YUV4MPEG2 stream to PPM images SYNOPSIS y4mtoppm [options] DESCRIPTION y4mtoppm converts a YUV4MPEG2 stream into a sequence of raw PPM images. Output is to stdout (but feel free to have the shell redirect to a file). Input is read from stdin, like all other YUV4MPEG2 filters and tools. YUV4MPEG2 streams contain…
NAME y4mtopnm – Convert a YUV4MPEG2 stream to PNM images SYNOPSIS y4mtopnm [options] DESCRIPTION y4mtopnm converts a YUV4MPEG2 stream into a sequence of raw PPM, PGM, or PAM images. (Technically, "pnm" comprises the PPM, PGM and PBM formats. PAM is a fourth format, which can effectively contain any of the other three, and more.) Output…
NAME y4mscaler – Scale/crop/translate a YUV4MPEG2 stream SYNOPSIS y4mscaler [options] < Y4Mstream > Y4Mstream DESCRIPTION y4mscaler is a general-purpose video scaler which operates on YUV4MPEG2 streams, as produced and consumed by the MJPEGtools such as lav2yuv and mpeg2enc(1). y4mscaler is meant to be used in a pipeline. Thus, input is from stdin, and output is…
NAME y4mdenoise – Motion-compensating YUV4MPEG-frame denoiser SYNOPSIS y4mdenoise [-v verbosity] [-p parallelism] [-r motion-search_radius] [-R color_motion-search_radius] [-t error_tolerance] [-T color_error_tolerance] [-z zero_motion_error_tolerance] [-Z color_zero_motion_error_tolerance] [-m match-count_throttle] [-M match-size_throttle] [-f reference_frames] [-B] [-I interlacing_type] < /dev/stdin > /dev/stdout DESCRIPTION y4mdenoise can be used to remove noise from images in a YUV4MPEG2 stream. This is useful for…
NAME y4mcolorbars – Create a YUV4MPEG2 stream containing a colorbar test pattern SYNOPSIS y4mcolorbars [options] DESCRIPTION y4mcolorbars creates a YUV4MPEG2 stream consisting entirely of frames containing a colorbar test pattern. The pattern attempts to reproduce the standard SMPTE EG-1-1990 colorbar test signal as faithfully as possible, given the constraints of the Y’CbCr colorspace. Output is…
NAME xzmore, lzmore – view xz or lzma compressed (text) files SYNOPSIS xzmore [file…] lzmore [file…] DESCRIPTION xzmore is a filter which allows examination of xz(1) or lzma(1) compressed text files one screenful at a time on a soft-copy terminal. To use a pager other than the default more, set environment variable PAGER to the…
NAME xzless, lzless – view xz or lzma compressed (text) files SYNOPSIS xzless [file…] lzless [file…] DESCRIPTION xzless is a filter that displays text from compressed files to a terminal. It works on files compressed with xz(1) or lzma(1). If no files are given, xzless reads from standard input. xzless uses less(1) to present its…
