```
public static void registerCustomMimeType(java.lang.String mimeType,
                                          java.lang.String codecPrefix,
                                          int trackType)
```
    Registers a custom MIME type. Most applications do not need to call this method, as handling of standard MIME types is built in. These built-in MIME types take precedence over any registered via this method. If this method is used, it must be called before creating any player(s).
    
    Parameters:
    
    mimeType - The custom MIME type to register.
    
    codecPrefix - The RFC 6381-style codec string prefix associated with the MIME type.
    
    trackType - The C.TRACK_TYPE_* constant associated with the MIME type. This value is ignored if the top-level type of mimeType is audio, video or text.
  - isAudio
```
public static boolean isAudio(java.lang.String mimeType)
```
    Whether the top-level type of mimeType is audio.
    
    Parameters:
    
    mimeType - The mimeType to test.
    
    Returns:
    
    Whether the top level type is audio.
  - isVideo
```
public static boolean isVideo(java.lang.String mimeType)
```
    Whether the top-level type of mimeType is video.
    
    Parameters:
    
    mimeType - The mimeType to test.
    
    Returns:
    
    Whether the top level type is video.
  - isText
```
public static boolean isText(java.lang.String mimeType)
```
    Whether the top-level type of mimeType is text.
    
    Parameters:
    
    mimeType - The mimeType to test.
    
    Returns:
    
    Whether the top level type is text.
  - isApplication
```
public static boolean isApplication(java.lang.String mimeType)
```
    Whether the top-level type of mimeType is application.
    
    Parameters:
    
    mimeType - The mimeType to test.
    
    Returns:
    
    Whether the top level type is application.
  - getVideoMediaMimeType

```
    Derives a audio sample mimeType from a codecs attribute.
    
    Parameters:
    
    codecs - The codecs attribute.
    
    Returns:
    
    The derived audio mimeType, or null if it could not be derived.

    Returns:
    
    The C.TRACK_TYPE_* constant that corresponds to a specified MIME type.
  - getEncoding
```
public static int getEncoding(java.lang.String mimeType)
```
