  - DefaultEncoderFactory
```
public DefaultEncoderFactory()
```
    Creates a new instance using the default encoder selector, a default VideoEncoderSettings, and with format fallback enabled.
  - DefaultEncoderFactory
```
public DefaultEncoderFactory(EncoderSelector videoEncoderSelector,
                             boolean enableFallback)
```
    Creates a new instance using a default VideoEncoderSettings.
  - DefaultEncoderFactory
```
public DefaultEncoderFactory(EncoderSelector videoEncoderSelector,
                             VideoEncoderSettings requestedVideoEncoderSettings,
                             boolean enableFallback)
```
    Creates a new instance.
    With format fallback enabled, when the requested Format is not supported, DefaultEncoderFactory finds a format that is supported by the device and configures the Codec with it. The fallback process may change the requested MIME type, resolution, bitrate, profile/level etc.
    Values in requestedVideoEncoderSettings could be adjusted to improve encoding quality and/or reduce failures. Specifically, VideoEncoderSettings.profile and VideoEncoderSettings.level are ignored for MimeTypes.VIDEO_H264. Consider implementing Codec.EncoderFactory if such adjustments are unwanted.
    requestedVideoEncoderSettings should be handled with care because there is no fallback support for it. For example, using incompatible VideoEncoderSettings.profile and VideoEncoderSettings.level can cause codec configuration failure. Setting an unsupported VideoEncoderSettings.bitrateMode may cause encoder instantiation failure.
    
    Parameters:
    
    videoEncoderSelector - The EncoderSelector.
    
    requestedVideoEncoderSettings - The VideoEncoderSettings.
    
    enableFallback - Whether to enable fallback.

  - createForAudioEncoding
```
public Codec createForAudioEncoding(Format format,
                                    List<String> allowedMimeTypes)
                             throws TransformationException
```
    Description copied from interface: Codec.EncoderFactory
    
    Returns a Codec for audio encoding.
    This method must validate that the Codec is configured to produce one of the allowedMimeTypes. The sample MIME type given in format is not necessarily allowed.
    
    Specified by:
    
    createForAudioEncoding in interface Codec.EncoderFactory
    
    Parameters:
    
    format - The Format (of the output data) used to determine the underlying encoder and its configuration values.
    
    allowedMimeTypes - The non-empty list of allowed output sample MIME types.
    
    Returns:
    
    A Codec for audio encoding.
    
    Throws:
    
    TransformationException - If no suitable Codec can be created.
  - createForVideoEncoding
```
public Codec createForVideoEncoding(Format format,
                                    List<String> allowedMimeTypes)
                             throws TransformationException
```
    Description copied from interface: Codec.EncoderFactory
    
    Returns a Codec for video encoding.
    This method must validate that the Codec is configured to produce one of the allowedMimeTypes. The sample MIME type given in format is not necessarily allowed.
    
    Specified by:
    
    createForVideoEncoding in interface Codec.EncoderFactory
    
    Parameters:
    
    format - The Format (of the output data) used to determine the underlying encoder and its configuration values. Format.sampleMimeType, Format.width and Format.height are set to those of the desired output video format. Format.rotationDegrees is 0 and Format.width >= Format.height, therefore the video is always in landscape orientation. Format.frameRate is set to the output video's frame rate, if available.
    
    allowedMimeTypes - The non-empty list of allowed output sample MIME types.
    
    Returns:
    
    A Codec for video encoding.
    
    Throws:
    
    TransformationException - If no suitable Codec can be created.
  - videoNeedsEncoding
```
public boolean videoNeedsEncoding()
```
    Description copied from interface: Codec.EncoderFactory
    
    Returns whether the video needs to be encoded because of encoder specific configuration.
    
    Specified by:
    
    videoNeedsEncoding in interface Codec.EncoderFactory
