$movie->getFrameHeight()	Return the height of the movie in pixels.
$movie->getFrameWidth()	Return the width of the movie in pixels.
$movie->getPixelFormat()	Return the pixel format of the movie.
$movie->getBitRate()	Return the bit rate of the movie or audio file in bits per second.
$movie->getVideoBitRate()	Return the bit rate of the video in bits per second. NOTE: This only works for files with constant bit rate.
$movie->getAudioBitRate()	Return the audio bit rate of the media file in bits per second.
$movie->getAudioSampleRate()	Return the audio sample rate of the media file in bits per second.
$movie->getFrameNumber()	Return the current frame index.
$movie->getVideoCodec()	Return the name of the video codec used to encode this movie as a string.
$movie->getAudioCodec()	Return the name of the audio codec used to encode this movie as a string.
$movie->getAudioChannels()	Return the number of audio channels in this movie as an integer.
$movie->hasAudio()	Return boolean value indicating whether the movie has an audio stream.
$movie->getFrame([Integer framenumber])	Returns a frame from the movie as an ffmpeg_frame object. Returns false if the frame was not found. framenumber - Frame from the movie to return. If no framenumber is specified, returns the next frame of the movie.
$movie->getNextKeyFrame()	Returns the next key frame from the movie as an ffmpeg_frame object. Returns false if the frame was not found.

ffmpeg_frame object methods

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.

ffmpeg_animated_gif object methods

Method	Description
$gif = new ffmpeg_animated_gif(String output_file_path, Integer width, Integer height, Integer frame_rate, [Integer loop_count])	create a new ffmpeg_animated_gif object output_file_path - Location in the filesystem where the animated gif will be written. width - Width of the animated gif. height - Height of the animated gif. frame_rate - Frame rate of the animated gif in frames per second.. loop_count - Number of times to loop the animation. Put a zero here to loop forever or omit this parameter to disable looping.
$frame->addFrame(ffmpeg_frame frame_to_add)	Add a frame to the end of the animated gif. frame_to_add - The ffmpeg_frame object to add to the end of the animated gif.
