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 ressources 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 ressources 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.
