NAME

       dtk_load_video_test - Load an test video as a texture

SYNOPSIS

       #include <dtk_video.h>

       dtk_htex dtk_load_video_test(int flags);

DESCRIPTION

       This  function  loads a test video file as a dynamic texture. The texture will then been tracked by an internal texture manager so that the
       next call will return the same texture handle, thus sparing the resources of the system.  If not specified by flags the video will  not	be
       played immediately and dtk_video_exec(3) should be called to do start playing.

       The argument flags is used to modify the creation. It should contains a bitwise OR combination of the following flags:

	      DTK_AUTOSTART : Indicates that the video should start immediately after creation.

	      DTK_NOBLOCKING : Indicates that the creation function should not block waiting that the video pipeline is fully running.

       A  dynamic  texture  can  be used the same way as a static texture (for example image file). The only difference is that the content of the
       texture changes automatically with the stream of video. This means that every time a shape using this texture is drawn,	the  latest  frame
       available from the video stream will be mapped on the shape.

       There is no need for a valid window to create successfully a texture, i.e.  creation of textures are completely decoupled from the creation
       of others resources and can even be created in one thread to be used in another one.

       Once a the texture is stopped being used, it should be destroyed by dtk_destroy_texture(3).

RETURN VALUE

       In case of success, the function returns the handle to the created texture.  In case of failure, NULL is returned.

THREAD SAFETY

       dtk_load_video_test() is thread-safe.
