MPEG2PLAY(1) MPEG2PLAY(1) 01 Jul 1994 NAME mpeg2play - X11 player for MPEG2 video streams SYNOPSIS mpeg2play [ -vn ] [ -on ] [ -l ] [ -q ] [ -s ssinfile ] inputfile [ upperfile ] DESCRIPTION mpeg2play decodes and displays MPEG-1 and MPEG-2 video streams on an 8-bit (or 24-bit) X11 display. OPTIONS -vn : Instructs mpeg2play to generate informative output about the sequence to stdout. Increasing level (-v1, -v2, etc.) results in more detailed output. -on : output format (0: X11, 1: none). -o1 is sometimes useful for benchmarking. -l : Setting this flag results in repeated display of the sequence. -8 : The local version of mpeg2play will use a 24-bit TrueColor visual if the display supports it. This flag tells it to stick to 8-bit PseudoColor. (This may be useful for images which are too large for shared memory to be usable in TrueColor, since using shared memory is typically twice as fast as not.) -q : Set this switch to suppress output of warnings to stderr. Usually a bad idea. -s ssinfile : Spatial scalable video is decoded in two passes. The -s option specifies the names of the output files from the first (lower layer) pass to the second (enhancement layer) pass. 'ssinfile' describes the name format of the lower layer pictures for spatial scalable sequences as a printf format string. It has to contain exactly one integer format descriptor (e.g. %d, %02d) and, a %c descriptor. The %d descriptor has to be before the %c. (See documentation under /home/graphics/mpeg/mpeg2play if you need to understand this.) infile : name of the file containing the MPEG stream. '-' denotes reading the stream from stdin. upperfile : is the name of the upper layer bitstream of an SNR scalable stream or a data partioning scalable bitstream ('infile' is the lower layer). - 1 - Formatted: May 9, 2025
