ImageVideo Contact Sheet *NIX (vcs for short) is ascript that creates a contact sheet (preview) fromvideos by taking still captures distributed overthe length of the video. The output image containsuseful information on the video such as codecs,file size, screen size, frame rate, and length.It requires mplayer, ImageMagick (convert andmontage), bc, and ffmpeg.License: GNU Lesser General Public License (LGPL)Changes:
0ms timestamps have been corrected (seconds were being used as ms too). The long-disabled black border after highlights has been re-added. A minimum length to use the end offset has been added.

sdl::overlay

pods::SDL::Overlay(3pm) 				User Contributed Perl Documentation				   pods::SDL::Overlay(3pm)

NAME

       SDL::Overlay - YUV Video overlay

   CATEGORY
       Core, Video, Structure

SYNOPSIS

       First import the following modules to get access to constants and functions needed for overlay.

	  use SDL;
	  use SDL::Video;
	  use SDL::Overlay;

       Init the video subsystem.

	  SDL::Init(SDL_INIT_VIDEO);

       Create a display to use.

	  my $display = SDL::Video::set_video_mode(640, 480, 32, SDL_SWSURFACE);

       Create and attach the display to a new overlay

	  my $overlay = SDL::Overlay->new( 100, 100, SDL_YV12_OVERLAY, $display);

DESCRIPTION

       A "SDL_Overlay" allows for video rendering on an "SDL_Surface" which is a display.

       The term 'overlay' is a misnomer since, unless the overlay is created in hardware, the contents for the display surface underneath the area
       where the overlay is shown will be overwritten when the overlay is displayed.

METHODS

   new ( $width, $height, $YUV_flag, $display)
       The constructor creates a SDL::Overlay of the specified width, height and format (see "YUV_Flags" list below of available formats), for the
       provided display.

       Note the 'display' argument needs to actually be the surface created by "SDL::Video::SetVideoMode" otherwise this function will segfault.

	  my $overlay = SDL::Overlay->new( $width, $height, $YUV_flag, $display );

       YUV_Flags

       More information on YUV formats can be found at <http://www.fourcc.org/indexyuv.htm> .

       o   SDL_YV12_OVERLAY  0x32315659  /* Planar mode: Y + V + U */

       o   SDL_IYUV_OVERLAY  0x56555949  /* Planar mode: Y + U + V */

       o   SDL_YUY2_OVERLAY  0x32595559  /* Packed mode: Y0+U0+Y1+V0 */

       o   SDL_UYVY_OVERLAY  0x59565955  /* Packed mode: U0+Y0+V0+Y1 */

       o   SDL_YVYU_OVERLAY  0x55595659  /* Packed mode: Y0+V0+Y1+U0 */

   format
       Overlay format (see YUV_Flags)

   w, h
       Width and height of overlay

   planes
       Number of planes in the overlay. Usually either 1 or 3

   pitches
       An array of pitches, one for each plane. Pitch is the length of a row in bytes.

   pixels
       As of release 2.3 direct right to overlay is disable.

       An array of pointers to the data of each plane. The overlay should be locked before these pointers are used.

       see SDL::Video::lock_YUV_overlay, SDL::Video::unload_YUV_overlay

   hw_overlay
       This will be set to 1 if the overlay is hardware accelerated.
