Method Detail

addTrack

public int addTrack(Format format)
             throws IOException

Description copied from interface: MovieWriter

Adds a track to the writer for a suggested input format.

The format should at least specify the desired FormatKeys.MediaType. The actual input format is a refined version of the suggested format. For example, if a MovieWriter only supports fixed frame rate video, then the MovieWriter will extend the format with that information.

If the suggested input format is not compatible, then an IOException is thrown. For example, if a MovieWriter only supports fixed frame rate video, but a format with variable frame rate was requested.

Specified by:

addTrack in interface MovieWriter

Parameters:

format - The desired input format of the track. The actual input format may be a refined version of the specified format.

Returns:

The track number.

Throws:

IOException

getFileFormat

public Format getFileFormat()
                     throws IOException

Description copied from interface: MovieWriter

Returns the file format.

Specified by:

getFileFormat in interface MovieWriter

Throws:

IOException

getTrackCount

public int getTrackCount()

Description copied from interface: MovieWriter

Returns the number of tracks.

Specified by:

getTrackCount in interface MovieWriter

getFormat

public Format getFormat(int track)

Description copied from interface: MovieWriter

Returns the media format of the specified track. This is a refined version of the format that was requested when the track was added. See MovieWriter.addTrack(org.monte.media.Format).

Specified by:

getFormat in interface MovieWriter

Parameters:

track - Track number.

Returns:

The media format of the track.

addVideoTrack

public int addVideoTrack(File dir,
                String filenameFormatter,
                int width,
                int height)

Adds a video track.

Parameters:

dir - The output directory.

filenameFormatter - a format string for a filename with a number, for example "frame_%d0000$.png";

width - the image width

height - the image height

Returns:

Returns the track index.

Throws:

IllegalArgumentException - if the width or the height is smaller than 1.

write

public void write(int track,
         BufferedImage image,
         long duration)
           throws IOException

Throws:

IOException

write

public void write(int track,
         Buffer buf)
           throws IOException

Description copied from interface: MovieWriter

Writes a sample into the specified track. Does nothing if the discard-flag in the buffer is set to true.

Specified by:

write in interface MovieWriter

Specified by:

write in interface Multiplexer

Parameters:

track - The track number.

buf - The buffer containing the sample data.

Throws:

IOException

writeSample

public void writeSample(int track,
               byte[] data,
               int off,
               int len,
               long duration,
               boolean isSync)
                 throws IOException

Throws:

IOException

writeSamples

public void writeSamples(int track,
                int sampleCount,
                byte[] data,
                int off,
                int len,
                long sampleDuration,
                boolean isSync)
                  throws IOException

Throws:

IOException

close

public void close()
           throws IOException

Description copied from interface: MovieWriter

Closes the writer.

Specified by:

Throws:

IOException

isVFRSupported

public boolean isVFRSupported()

isDataLimitReached

public boolean isDataLimitReached()

Description copied from interface: MovieWriter

Returns true if the limit for media data has been reached. If this limit is reached, no more samples should be added to the movie.

This limit is imposed by data structures of the movie file which will overflow if more samples are added to the movie.

FIXME - Maybe replace by getCapacity():long.

Specified by:

isDataLimitReached in interface MovieWriter

getDuration

public Rational getDuration(int track)

Returns the sampleDuration of the track in seconds.

Specified by:

getDuration in interface MovieWriter

isEmpty

public boolean isEmpty(int track)

Description copied from interface: MovieWriter
