Hi all,
in a Qt desktop app (C++) I try to use libVLC function libvlc_video_set_logo_string() and libvlc_video_set_logo_int(). Could someone please explain which kind of parameter needs to be set and what they mean?

libvlc_logo_enable - understood - int: 1 -> enable, 0 -> disable
libvlc_logo_file - partly understood - string: path to local image file. What are other comma separated arguments in string?
libvlc_logo_x - not understood - int: is this size or position?
libvlc_logo_y - not understood - int: is this size or position?
libvlc_logo_delay - understood - int: delay in ms
libvlc_logo_repeat - not understood - horizontal / vertical repeat?
libvlc_logo_opacity - understood - int: 0 ... 255
libvlc_logo_position - not understood

Thank you very much for your help!

Best regards,
Jörg

OK, found it in command line help:

      --logo-file=<string>       Logo filenames
          Full path of the image files to use. Format is <image>[,<delay in
          ms>[,<alpha>]][;<image>[,<delay>[,<alpha>]]][;...]. If you only have
          one file, simply enter its filename.
      --logo-x=<integer [-2147483648 .. 2147483647]>
                                 X coordinate
          X coordinate of the logo. You can move the logo by left-clicking it.
      --logo-y=<integer [-2147483648 .. 2147483647]>
                                 Y coordinate
          Y coordinate of the logo. You can move the logo by left-clicking it.
      --logo-delay=<integer [-2147483648 .. 2147483647]>
                                 Logo individual image time in ms
          Individual image display time of 0 - 60000 ms.
      --logo-repeat=<integer [-2147483648 .. 2147483647]>
                                 Logo animation # of loops
          Number of loops for the logo animation.-1 = continuous, 0 = disabled
      --logo-opacity=<integer [0 .. 255]>
                                 Opacity of the logo
          Logo opacity value (from 0 for full transparency to 255 for full
          opacity).
      --logo-position={0 (Center), 1 (Left), 2 (Right), 4 (Top), 8 (Bottom), 5 (Top-Left), 6 (Top-Right), 9 (Bottom-Left), 10 (Bottom-Right)}
                                 Logo position
          Enforce the logo position on the video (0=center, 1=left, 2=right,
          4=top, 8=bottom, you can also use combinations of these values, eg 6
          = top-right).

Thanks anyway,
Jörg
