   3. Using

1. Installation

   You need these packages: if your system is debian: perl,
   perl-modules, libmplayer-perl (if the mplayertv.*deb was
   installed). On RPM based systems: perl-Gtk2, perl-Glib,
   perl-ExtUtils-Depends, perl-ExtUtils-PkgConfig. Downloadable
   at SourceForge.net. You need also mplayer and scantv. scantv
   is part of xawtv. Compile mplayer with v4l, v4l2 or with
   bsdbt848 driver.

   Unpack file mplayerTV-0.2.1rc1.tar.gz then run install script:
tar -xvzf mplayerTV-0.2.1rc1.tar.gz
cd mplayerTV-0.2.1rc1
./install


   Under Debian run these commands as root:
dpkg -i mplayertv_0.2.1rc1-1_all.deb libmplayer-perl_0.04-1_all.deb

2. Configuration

   Choice File->Configuration menu and set followings on Video
   page:
     _________________________________________________________

2.1. Video

   TV driver
          If you have Linux kernel version 2.4 or older then you
          can use v4l driver. If you have version 2.6 you can use
          v4l2 driver. You can use the dummy driver for testing.

          Under BSD systems you can use the bsdbt848 driver (not
          tested yet).

   TV device
          Name of the tuner device (optional). The default is
          /dev/video.

   Video output driver
          Used for showing video. The good choices are: xv, gl2,
          sdl (or the driver what you use in mplayer :).

   Video output subdriver
          You can select a subdriver of output driver.

   Output format of tuner
          In some cases you need to change the output format of
          the tuner. Example: i420 for Pinnacle PCTV USB2 tuner.

   Norm
          Norm of TV broadcast: PAL (Europe), SECAM, NTSC (USA,
          Japan), etc.

   Input
          You can select the input of the tuner card. Typical
          inputs are: #0 Television, #1 Composite, #2 S-Video.
          The mplayerTV gives only a number to mplayer (0, 1 or
          2) and the sequence can change.

   Ratio
          Ratio of picture: 4:3 or 16:9. The default ratio is
          4:3.

   Channel list
          The list of channel frequencies. In Hungary:
          europe-east.

   OSD
          If enabled the On-Screen-Display is on when mplayer is
          starting. If mplayer is running you can switch on and
          off with 'o' key.

   Start in full screen
          If enabled the mplayer starts in full screen mode. If
          mplayer is running you can switch on and off with 'f'
          key.

   Capture size
          The size of picture captured by tuner. The default is
          768x576.
     _________________________________________________________

2.2. Channels

   You can scan for channels on Channels page now. Click to Scan
   button. If program exits you maybe see some channel names.

   Name, Channel
          Click to a name of channel and you will see the channel
          number on the right side.

   Brightness, Contrast, Hue, Saturation, Volume
          There is five parameter per each channel: brightness,
          contrast, hue, saturation and volume.

   You must click to Modify button to store new settings. The
   selected channel will be deleted if you click to Delete
   button. With New button you can add a new element to the list.
   You can move up and down the selected channel if you click to
   Up or Down button. When mplayer is running and you click to a
   channel name then mplayerTV changes channel but the settings
   will be applied after using Save button.
     _________________________________________________________

2.3. General

   The Pre-exec command will be executed before mplayer. The
   Post-exec command will be executed after mplayer exits.

   You can set the path of Terminal on the General page. But it
   is unnecessary if the environment variable PATH is OK. The
   default terminal emulator is xterm. Warning! The
   x-terminal-emulator does not work if it is linked to
   gnome-terminal. gnome-terminal is not xterm compatible. In
   this case set it to gnome-terminal.
     _________________________________________________________

2.4. Filters

   You can set parameters of video filters on Filters page. The
   default settings are good in most cases. You can switch on a
   filter with the Activate this filter checkbox. Some of them
   eats the CPU time (denoise3d and hqdenoise3d). So do not
   activate all of them except you have a mainframe.
     _________________________________________________________

2.4.1. Postprocessing filter

   Most of filters have a local menu in this page. You can
   activate the local menu with right-click. The Auto off: The
   mplayer automatically switch off a filter if CPU is too slow.
   The Chroma filtering: Do chrominance filtering (The default is
   on).

   A deblock 閟 dering sz鹯鮧 igaz醔髄 csak az MPEG2-es
   form醫umban (kis s醰sz閘ess間gel) sug醨zott ad醩okn醠 lehet
   l閚yeges, ahol gyors mozg醩okn醠 n間yzeteket lehet l醫ni. I
   think the Linear blend deinterlacel is the best deinterlacer.
   Another good filter is the Temporal noise reducer.
     _________________________________________________________

2.4.2. Denoise and HQDenoise

   Another temporal noise reducer but these eat more CPU.
     _________________________________________________________

2.4.3. Equalizer and Equalizer 2

   Switch on one of them if your video output driver does not
   support the contrast and brightness changing. Equalizer 2 is
   slower than equalizer but eq2 support gamma.

   If you want set different brightness and contrast per channel
   and your does not support you must switch on one of them.

3. Using

   You can run this program with following switches:

   -w
          Run immediately mplayer.

   -h
          Show a brief help.

   -v
          Show program version and release date.

   -c
          Show copyright informations.

   -d
          Run program in verbose mode (for debugging).

   -D
          Run program in very verbose mode (for debugging).

   Using mplayer (the defaults): Use 'f' for toggling fullscreen
   mode, 'q' for quit. If the audio is captured from tuner you
   can use the '/' and '*' keys for changing volume. You can
   change the contrast with '1' and '2', the brightness with '3'
   and '4', hue with '5' and '6' and saturation with '7' and '8'.

   See mplayer's manual for further informations.
