SDL::Video(3) User Contributed Perl Documentation SDL::Video(3)NAME
SDL::Video - a SDL perl extension
SYNOPSIS
$video = new SDL::Video ( -name => 'pr0n.mpg' );
DESCRIPTION
"SDL::Video" adds support for MPEG video to your SDL Perl application. Videos are objects bound to surfaces, whose playback is controled
through the object's interface.
METHODS
o "SDL::Video::error()" returns any error messages associated with playback
o "SDL::Video::audio(bool)" enables or disables audio playback, (on by default)
o "SDL::Video::video(bool)" enables or disable video playback, (on by default)
o "SDL::Video::loop(bool)" enables or disable playback looping (off by default)
o "SDL::Video::volume(int)" set the volume as per the mixer volume
o "SDL::Video:display(surface)" binds the clip to a display surface
o "SDL::Video::scale([x,y]|[surface]|int)" scales the clip by either x,y factors, scales to the image dimensions, or a single scalar.
o "SDL::Video::play()" plays the video clip, call "SDL::Video::display()" before playing
o "SDL::Video::pause()" pauses video playback
o "SDL::Video::stop()" stops video playback
o "SDL::Video::rewind()" resets the clip to the beginning
o "SDL::Video::seek(offset)" seeks to a particular byte offset
o "SDL::Video::skip(time)" skips to a particular time
o "SDL::Video::region(rect)" takes a SDL::Rect and defines the display area
o "SDL::Video::frame(int)" renders a specific frame to the screen
o "SDL::Video::info()" returns a new "SDL::MPEG" object reflecting the current status
o "SDL::Video::status()" returns either SMPEG_PLAYING or SMPEG_STOPPED or SMPEG_ERROR

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.
