Constructor Detail

GSMovie

public GSMovie(processing.core.PApplet parent,
               java.lang.String filename)

Creates an instance of GSMovie loading the movie from filename.

Parameters:

parent - PApplet

filename - String

Method Detail

delete

public void delete()

Releases the gstreamer resources associated to this movie object. It shouldn't be used after this.

Overrides:

delete in class processing.core.PImage

dispose

public void dispose()

Same as delete.

printElements

public void printElements()

Prints all the gstreamer elements currently used in the current player instance.

setPixelDest

public void setPixelDest(java.lang.Object dest)

Sets the object to use as destination for the frames read from the stream. The color conversion mask is automatically set to the one required to copy the frames to OpenGL.

Parameters:

Object - dest

setPixelDest

public void setPixelDest(java.lang.Object dest,
                         boolean copy)

Sets the object to use as destination for the frames read from the stream. The color conversion mask is automatically set to the one required to copy the frames to OpenGL. If copy is true, then the frames are copied into new buffer objects, this can help solve threading problems when playing back a large number of videos.

Parameters:

Object - dest

boolean - copy

setPixelDest

public void setPixelDest(java.lang.Object dest,
                         java.lang.String mask,
                         boolean copy)

Sets the object to use as destination for the frames read from the stream. If copy is true, then the frames are copied into new buffer objects, this can help solve threading problems when playing back a large number of videos.

Parameters:

Object - dest

String - mask

boolean - copy

setEventHandlerObject

public void setEventHandlerObject(java.lang.Object obj)

Uses a generic object as handler of the movie. This object should have a movieEvent method that receives a GSMovie argument. This method will be called upon a new frame read event.

getSourceWidth

public int getSourceWidth()

Get the width of the source video. Note: calling this method repeatedly can slow down playback performance.

Returns:

int

getSourceHeight

public int getSourceHeight()

Get the height of the source video. Note: calling this method repeatedly can slow down playback performance.

Returns:

int

getSourceFrameRate

public float getSourceFrameRate()

Get the original framerate of the source video. Note: calling this method repeatedly can slow down playback performance.

Returns:

float

frameRate

public void frameRate(float ifps)

Set how often new frames are to be read from the movie. Does not actually set the speed of the movie playback, that's handled by the speed() method.

Parameters:

float - ifps

See Also:

speed

speed

public void speed(float irate)

Set a multiplier for how fast/slow the movie should be run. The default is 1.0. speed(2) will play the movie at double speed (2x). speed(0.5) will play at half speed. speed(-1) will play backwards at regular speed.

Parameters:

float - irate

duration

public float duration()

Get the full length of this movie (in seconds).

Returns:

float

time

public float time()

Return the current time in seconds. Only works for constant framerate videos.

Returns:

float

length

public long length()

Get the full length of this movie (in frames). Only works for constant framerate videos.

Returns:

float

frame

public int frame()

Return the current frame.

Returns:

int

jump

public void jump(float where)

Jump to a specific location (in seconds). The number is a float so fractions of seconds can be used.

Parameters:

float - where

jump

public void jump(int frame)

Jump to a specific frame.

Parameters:

frame - int

ready

public boolean ready()

Returns true if the stream is already producing frames.

Returns:

boolean

newFrame

public boolean newFrame()

Returns true if a new frame has been read to the pixels array with the read() method.

Returns:

boolean

oldFrame

public void oldFrame()

Sets the new frame flag to false. This is useful to avoid reading pixels array when there is no new frame data.

available

public boolean available()

Return the true or false depending on whether there is a new frame ready to be read.

Returns:

boolean

isPlaying

public boolean isPlaying()

Returns whether the movie is playing or not.

Returns:

boolean

isPaused

public boolean isPaused()

Returns whether the movie is paused or not. If isPlaying() and isPaused() both return false it means that the movie is stopped.

Returns:

boolean

isLooping

public boolean isLooping()

Returns whether the movie is looping or not.

Returns:

boolean

isSeeking

public boolean isSeeking()

Returns true if stream is completing a seeking (jump) operation.

Returns:

boolean

play

public void play()

Begin playing the movie, with no repeat.

loop

public void loop()

Begin playing the movie, with repeat.

noLoop

public void noLoop()

Shut off the repeating loop.

pause

Stop the movie, and rewind.

read

public void read()

Reads the current video frame.

goToBeginning

public void goToBeginning()

Jumps to the first frame of the movie.

goToEnd
