Method Detail

setFormat

public T setFormat(String format)

Force input or output file format. The format is normally auto detected for input files and guessed from the file extension for output files, so this option is not needed in most cases.

Parameters:

format - format

Returns:

this

setDuration

public T setDuration(long durationMillis)

When used as an input option, limit the duration of data read from the input file.

When used as an output option, stop writing the output after its duration reaches duration.

Parameters:

durationMillis - duration in milliseconds

Returns:

this

setDuration

public T setDuration(long duration,
                     TimeUnit timeUnit)

Parameters:

duration - duration

timeUnit - unit of duration

Returns:

this

See Also:

setDuration(long)

setPosition

public T setPosition(long positionMillis)

When used as an input option, seeks in this input file to position.

Note that in most formats it is not possible to seek exactly, so ffmpeg will seek to the closest seek point before position. When transcoding and -accurate_seek is enabled (the default), this extra segment between the seek point and position will be decoded and discarded. When doing stream copy or when -noaccurate_seek is used, it will be preserved.

When used as an output option (before an output url), decodes but discards input until the timestamps reach position.

Parameters:

positionMillis - position in milliseconds.

Returns:

this

setPosition

public T setPosition(long position,
                     TimeUnit unit)

Parameters:

position - position.

unit - time unit

Returns:

this

See Also:

setPosition(long)

setPositionEof

public T setPositionEof(long positionEofMillis)

Like the setPosition(long) (-ss) option but relative to the "end of file". That is negative values are earlier in the file, 0 is at EOF.

Parameters:

positionEofMillis - position in milliseconds, relative to the EOF

Returns:

this

setPositionEof

public T setPositionEof(long positionEof,
                        TimeUnit unit)

Like the setPositionEof(long) (-ss) option but relative to the "end of file". That is negative values are earlier in the file, 0 is at EOF.

Parameters:

positionEof - position, relative to the EOF

unit - time unit

Returns:

this

See Also:

setPositionEof(long)

addCodecCopy

public T addCodecCopy()

Sets special "copy" codec for all streams

Returns:

this

addCodecCopy

public T addCodecCopy(StreamSpecifier streamSpecifier)

Sets special "copy" codec for specified streams

Returns:

this

addCodec

public T addCodec(StreamSpecifier streamSpecifier,
                  String codecName)

addOption

public T addOption(Option option)

Add custom option. Intended for options, that are not yet supported by jaffree

Parameters:

option - option to add

Returns:

this

addOption

public T addOption(String key,
                   String value)

addOption

public T addOption(String key)

buildOptions

public abstract List<Option> buildOptions()

buildCommonOptions

protected List<Option> buildCommonOptions()
