config

)

Open a video input module and return control object.

Opening a video input module selects, connects to, and configures a video source for other video operations. Once this call has returned, other APIs can be invoked. @oaram config A configuration string, consisting of a series of space-separated configuration tokens. While the configuration string options are largely platform- and system-dependent, the token "-module=X" where X is a video input module name is always accepted. For information on configuration options, see https://github.com/artoolkitx/artoolkitx/wiki/artoolkitX-video-module-configuration-reference

arVideoOpenAsync ar2VideoOpen ar2VideoOpenAsync arVideoClose ar2VideoClose

Returns

NULL in case of error, or allocates and returns a pointer to an AR2VideoParamT structure if successful. The allocation is dispoed of by ar2VideoClose.

Here is the call graph for this function:

ar2VideoOpenAsync()

AR2VideoParamT * ar2VideoOpenAsync	(	const char *	config,
		void(*)(void *)	callback,
		void *	userdata
	)

Open a video input module, and return control object, invoking a callback once opening is complete.

Opening a video input module selects, connects to, and configures a video source for other video operations. This variant returns immediately while continuing the opening operation asynchronously, invoking a user-supplied callback once opening has completed. The only API permissible to call between this function and the invocation of the callback is ar2VideoGetModule. @oaram config A configuration string, consisting of a series of space-separated configuration tokens. While the configuration string options are largely platform- and system-dependent, the token "-module=X" where X is a video input module name is always accepted. For information on configuration options, see https://github.com/artoolkitx/artoolkitx/wiki/artoolkitX-video-module-configuration-reference

Parameters

callback	The callback to invoke once opening is complete. In most cases, the callback will be invoked on a different thread, so care must be taken if the caller is sensitive to this.
userdata	An arbitrary pointer which will be passed to the callback.
