Revision as of 19:15, 24 March 2007

Configuration file supplied with VZ is used for hardware dependent configuration.

Configuration file has XML format and consists of some section that describes some module behaviour, main sections described bellow.

Contents 1 main 2 vzOutput 3 vzMain 4 tvspec 5 tcpserver 6 serserver 7 streamalpha 8 nullvideo 9 bluefish

main

	<module name="main">
		<!-- output module name -->
<!--		<param name="output" value="bluefish" /> -->
		<param name="output" value="nullvideo" />
<!--		<param name="output" value="streamalpha" />    --> 

		<!-- font (.ttf) files path -->
		<param name="font_path" value="C:\WINDOWS\Fonts" />
	</module>

This section configure some global vz functionality.

output paramter defines which output module will be used. By default nullvideo is used. For bluefish output module using uncomment string with bluefish value of parameter output.

font_path parameter is used to point to main Truetype storage directory. Override it if you need. Additionaly fonts can be stored in local to vz.exe folder fonts.

vzOutput

	<module name="vzOutput">
		<!--
			enable to use asyncronous reading of framebuffer
			based on 'GL_EXT_pixel_buffer_object' GL extension
		-->
<!--		<param name="use_offscreen_buffer" value="defined" />  -->
	</module>

This section was used to configure vzOutput.dll. Main purpose of use this section is override method used for rendered surface download: classic glReadPixel or GL_EXT_framebuffer_object. For current moment for modern card i found no difference in using second method. Possible will be dropped in future.

vzMain

	<module name="vzMain">
		<!--  define field-based rendering mode used -->
		<param name="fields" value="defined" /> 

		<!-- enable -->
		<param name="enable_GL_SRC_ALPHA_SATURATE" value="defined"/>
	</module>

You can override parameter fields (comment out) to enable "progressive" rendering, not field based (do it with caution - enabling frame-based rendering makes some animation become not smooth) enable_GL_SRC_ALPHA_SATURATE parameter provides additinal configuration of glBlendFuncSeparateEXT function: GL_ONE_MINUS_DST_ALPHA or GL_SRC_ALPHA_SATURATE as parameter for source distination.

tvspec

	<module name="tvspec">
		<!-- long TV_FRAME_DUR_MS;// frame length (time period) (ms)  -->
		<param name="TV_FRAME_DUR_MS" value="40"/>

		<!-- long TV_FRAME_HEIGHT;	// frame height (px) -->
		<param name="TV_FRAME_HEIGHT" value="576"/>

		<!-- long TV_FRAME_WIDTH;// frame width (px) -->
		<param name="TV_FRAME_WIDTH" value="720"/>

		<!-- long TV_FRAME_1ST;	// first field in frame -->
		<param name="TV_FRAME_1ST" value="0"/>

		<!-- long TV_FRAME_PS;	// frames per seconds -->
		<param name="TV_FRAME_PS" value="25"/>
	</module>

Defines geometric rendering parameters. By default configured for PAL world.

tcpserver

	<module name="tcpserver">
		<param name="enable" value="defined"/>
		<param name="port" value="8001"/>
		<param name="bufsize" value="8192"/>
	</module>

This section enables IP Control server, parameters defines port and bufsize. Modify port parameter if you are already has service binded to local IP port 8001.

serserver

<!--	<module name="serserver">
		<param name="enable" value="defined"/>
		<param name="serial_port_name" value="COM1:"/>
		<param name="bufsize" value="8192"/>
	</module> -->

This section enables Serial Control server. This section is commented out by default.

If you are going to use serial link to control vz uncomment this section and modify parameter serial_port_name to avoid conflicts with other services.

streamalpha

	<module name="streamalpha">
<!--

		<param name="MODE_PAL" value="defined"/>
		<param name="MULTIPLY_ALPHA_OFF" value="defined"/>
		<param name="SWITCH_OUPUT_ON_PREVIEW_OFF" value="defined"/>
	</module>

nullvideo
