# mpeg\_blocks(1)

Analyze macroblocks in MPEG-1 bitstreams

## NAME

mpeg\_blocks - Analyze macroblocks in MPEG-1 bitstreams

## SYNOPSIS

**mpeg\_blocks mpegfile** \[ ***ordered \| ordered2 \| mbordered \|*** ***fs4 \| fs2 \| fs2fast \| hybrid \|*** ***hybrid2*** \]

## DESCRIPTION

mpeg\_blocks provides an easy-to-use graphical interface to look at  MPEG streams.  It operates by playing a video stream in one window, while another window displays the block type and motion vectors for each block in the current frame.

## NOTES

The player expects MPEG-1 video or system layer streams (without D-frames).

This is version 1.0, the initial public release.
