ffmpeg-php API documentation ffmpeg_frame

ffmpeg-php API documentation

Method	Description
$frame = new ffmpeg_frame(Resource gd_image)	Create a frame object from a GD image. NOTE: This function will not be available if GD is not enabled.
$frame->getWidth()	Return the width of the frame.
$frame->getHeight()	Return the height of the frame.
$frame->getPTS() alias $frame->getPresentationTimestamp()	Return the presentation time stamp of the frame.
$frame->resize(Integer width, Integer height [, Integer crop_top [, Integer crop_bottom [, Integer crop_left [, Integer crop_right ]]]])	Resize and optionally crop the frame. (Cropping is built into ffmpeg resizing so I'm providing it here for completeness.) width - New width of the frame (must be an even number). height - New height of the frame (must be an even number). croptop - Remove [croptop] rows of pixels from the top of the frame. cropbottom - Remove [cropbottom] rows of pixels from the bottom of the frame. cropleft - Remove [cropleft] rows of pixels from the left of the frame. cropright - Remove [cropright] rows of pixels from the right of the frame. NOTE: Cropping is always applied to the frame before it is resized. Crop values must be even numbers.
$frame->crop(Integer crop_top [, Integer crop_bottom [, Integer crop_left [, Integer crop_right ]]])	Crop the frame. croptop - Remove [croptop] rows of pixels from the top of the frame. cropbottom - Remove [cropbottom] rows of pixels from the bottom of the frame. cropleft - Remove [cropleft] rows of pixels from the left of the frame. cropright - Remove [cropright] rows of pixels from the right of the frame. NOTE: Crop values must be even numbers.
$frame->toGDImage()	Returns a truecolor GD image of the frame. NOTE: This function will not be available if GD is not enabled.
