NAME

       dtk_load_video_tcp - Load an video stream via TCP connection as a texture

SYNOPSIS

       #include <dtk_video.h>

       dtk_htex dtk_load_video_tcp(int flags, const char *host, int port);

DESCRIPTION

       This  function  loads  as  a dynamic texture the video stream broadcasted over the network via TCP by the server host on the port port. The
       texture will then been tracked by an internal texture manager so that the next call using the same host and port arguments 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_tcp() is thread-safe.
