aatv - A simple aalib-based TV program for meteor/bktr devices on FreeBSD
       Robert Watson <rwatson@FreeBSD.org>

  Introduction

aatv renders meteor/bktr video input using aalib, an ascii art library
available under the LGPL.  There's support for a tuner, but I can't
test it as I don't have a frame sync on my tuner port, causing aatv
to hang waiting for a frame.  If it doesn't work, try changing the
device number in the source to something else.

  Building

Install the aalib package/port, then build aatv.  There are some
compile-time toggles in aatv.c, such as "quiet" and "cleanup_on_sane_exit"
which respectively prevent debugging/frame output to stdout, and cause
the terminal to be cleaned up on exit.  To build the aatv binary, just
run:

    make

Running

aatv accepts various aalib arguments to set display type, permissible
characters for output, etc.

    ./aatv

You might want to consider things like:

    ./aatv -driver curses
    ./aatv -eight -inverse

Usage

    Key    Usage
    b      Lower brightness
    B      Raise brightness
    c      Lower contrast
    C      Raise contrast
    r      Set RCA as source
    s      Set SVideo as source
    t      Set Tuner as source (probably broken)
    +      Go up a channel (probably broken)
    -      Go down a channel (probably broken)
    q      Quit

Currently, aatv doesn't support the tuner or extended bktr input types.
It's really just a question of sticking the right ioctl's in video.c and
adding keypresses to the event loop.
