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
Choice -> menu and set followings on Video page:
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).
Name of the tuner device (optional). The default is /dev/video.
Used for showing video. The good choices are: xv, gl2, sdl (or the driver what you use in mplayer :).
You can select a subdriver of output driver.
In some cases you need to change the output format of the tuner. Example: i420 for Pinnacle PCTV USB2 tuner.
Norm of TV broadcast: PAL (Europe), SECAM, NTSC (USA, Japan), etc.
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 of picture: 4:3 or 16:9. The default ratio is 4:3.
The list of channel frequencies. In Hungary: europe-east.
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.
If enabled the mplayer starts in full screen mode. If mplayer is running you can switch on and off with 'f' key.
The size of picture captured by tuner. The default is 768x576.
You can scan for channels on Channels page now. Click to button. If program exits you maybe see some channel names.
Click to a name of channel and you will see the channel number on the right side.
There is five parameter per each channel: brightness, contrast, hue, saturation and volume.
You must click to button to store new settings. The selected channel will be deleted if you click to button. With button you can add a new element to the list. You can move up and down the selected channel if you click to or button. When mplayer is running and you click to a channel name then mplayerTV changes channel but the settings will be applied after using button.
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.
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.
Most of filters have a local menu in this page. You can activate the local menu with right-click. The : The mplayer automatically switch off a filter if CPU is too slow. The : Do chrominance filtering (The default is on).
A deblock és dering szűrők igazából csak az MPEG2-es formátumban (kis sávszélességgel) sugárzott adásoknál lehet lényeges, ahol gyors mozgásoknál négyzeteket lehet látni. I think the Linear blend deinterlacel is the best deinterlacer. Another good filter is the Temporal noise reducer.
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.
You can run this program with following switches:
Run immediately mplayer.
Show a brief help.
Show program version and release date.
Show copyright informations.
Run program in verbose mode (for debugging).
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.
