- Method Detail
  - registerCustomMimeType
```
public static void registerCustomMimeType(String mimeType,
                                          String codecPrefix,
                                          @com.google.android.exoplayer2.C.TrackType 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 codec string prefix associated with the MIME type.
    
    trackType - The track type 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(@Nullable
                              String mimeType)

  - isVideo
```
public static boolean isVideo(@Nullable
                              String mimeType)
```
    Returns whether the given string is a video MIME type.
  - isText
```
public static boolean isText(@Nullable
                             String mimeType)
```
    Returns whether the given string is a text MIME type, including known text types that use "application" as their base type.
  - isImage
```
public static boolean isImage(@Nullable
                              String mimeType)

                                               String codec)
```
    Returns true if it is known that all samples in a stream of the given MIME type and codec are guaranteed to be sync samples (i.e., C.BUFFER_FLAG_KEY_FRAME is guaranteed to be set on every sample).
    
    Parameters:
    
    mimeType - The MIME type of the stream.
    
    codec - The RFC 6381 codec string of the stream, or null if unknown.
    
    Returns:

    Returns the first video MIME type derived from an RFC 6381 codecs string.
    
    Parameters:
    
    codecs - An RFC 6381 codecs string.
    
    Returns:
    
    The first derived video MIME type, or null.
  - containsCodecsCorrespondingToMimeType

```
    Returns whether the given codecs string contains a codec which corresponds to the given mimeType.
    
    Parameters:
    
    codecs - An RFC 6381 codecs string.
    
    mimeType - A MIME type to look for.
    
    Returns:
