## org.monte.media.converter
Class FrameRateConverter

    java.lang.Object
      org.monte.media.AbstractCodec
          org.monte.media.AbstractVideoCodec
              org.monte.media.converter.FrameRateConverter

All Implemented Interfaces:
  Codec

    public class FrameRateConverter

extends AbstractVideoCodec

This codec converts frames from one frame rate into another.

Makes frames longer if the output time is behind the input time. Drops frames if the output time runs away from the input time.

The output of the converter has a variable frame rate but it may still contain identical frames. Thus an additional conversion step with `FFRtoVFRConverter` or `VFRtoFFRConverter` is needed.

This codec is needed when the input source has a different frame rate than the output sink.

Constructor Detail

### FrameRateConverter

    public FrameRateConverter()

Method Detail

### getOutputFormats

    public Format[] getOutputFormats(Format input)

  Description copied from interface: `Codec`
  Lists all of the output formats that this codec can generate with the provided input format. If the input format is null, returns all supported output formats.

  Specified by:
    `getOutputFormats` in interface `Codec`
  Overrides:
    `getOutputFormats` in class `AbstractCodec`

### setOutputFormat

    public Format setOutputFormat(Format f)

  Description copied from interface: `Codec`
  Sets the output format. Returns the format that was actually set. This is the closest format that the Codec supports. Returns null if the specified format is not supported and no reasonable match could be found.

  Specified by:
    `setOutputFormat` in interface `Codec`
  Overrides:
    `setOutputFormat` in class `AbstractCodec`

### reset

    public void reset()

  Description copied from class: `AbstractCodec`
  Empty implementation of the reset method. Don't call super.

  Specified by:
    `reset` in interface `Codec`
  Overrides:
    `reset` in class `AbstractCodec`

### process

    public int process(Buffer in,
                       Buffer out)

  Description copied from interface: `Codec`
  Performs the media processing defined by this codec.

  Copies the data from the input buffer into the output buffer.

  Returns:
    A combination of processing flags.
