NAME

       dtk_load_video_udp - Load an video stream via UDP connection as a texture

SYNOPSIS

       #include <dtk_video.h>

       dtk_htex dtk_load_video_udp(int flags, int port);

DESCRIPTION

       This  function  loads  as  a  dynamic  texture  the  video stream broadcasted over the network via UDP by
       listening to the port port. The texture will then been tracked by an internal texture manager so that the
       next call using the same 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_udp() is thread-safe.
