  - equals
```
public boolean equals(Object mediaFormat)
```
    Implements MediaFormat#equals(Object) and actually compares the encapsulated JMF Format instances.
    
    Specified by:
    
    equals in interface MediaFormat
    
    Overrides:
    
    equals in class MediaFormatImpl<javax.media.format.VideoFormat>
    
    Parameters:
    
    mediaFormat - the object that we'd like to compare this one to
    
    Returns:
    
    true if the JMF Format instances encapsulated by this instance and their other characteristics are equal; false, otherwise.
    
    See Also:
    
    MediaFormatImpl.equals(Object)
  - formatParametersAreEqual
```
protected boolean formatParametersAreEqual(Map<String,String> fmtps1,
                                           Map<String,String> fmtps2)
```
    Determines whether a specific set of format parameters is equal to another set of format parameters in the sense that they define an equal number of parameters and assign them equal values. Since the values are Strings, presumes that a value of null is equal to the empty String.
    The two Map instances of format parameters to be checked for equality are presumed to be modifiable in the sense that if the lack of a format parameter in a given Map is equivalent to it having a specific value, an association of the format parameter to the value in question may be added to or removed from the respective Map instance for the purposes of determining equality.
    Takes into account RFC 3984 "RTP Payload Format for H.264 Video" which says that "[w]hen the value of packetization-mode [format parameter] is equal to 0 or packetization-mode is not present, the single NAL mode, as defined in section 6.2 of RFC 3984, MUST be used."
    
    Overrides:
    
    formatParametersAreEqual in class MediaFormatImpl<javax.media.format.VideoFormat>
    
    Parameters:
    
    fmtps1 - the first set of format parameters to be tested for equality
    
    fmtps2 - the second set of format parameters to be tested for equality
    
    Returns:
    
    true if the specified sets of format parameters are equal; false, otherwise
    
    See Also:
    
    MediaFormatImpl.formatParametersAreEqual(Map, Map)
  - formatParametersAreEqual
```
public static boolean formatParametersAreEqual(String encoding,
                                               Map<String,String> fmtps1,
                                               Map<String,String> fmtps2)
```
    Determines whether a specific set of format parameters is equal to another set of format parameters in the sense that they define an equal number of parameters and assign them equal values. Since the values are Strings, presumes that a value of null is equal to the empty String.
    The two Map instances of format parameters to be checked for equality are presumed to be modifiable in the sense that if the lack of a format parameter in a given Map is equivalent to it having a specific value, an association of the format parameter to the value in question may be added to or removed from the respective Map instance for the purposes of determining equality.
    
    Parameters:
    
    encoding - the encoding (name) related to the two sets of format parameters to be tested for equality
    
    fmtps1 - the first set of format parameters to be tested for equality
    
    fmtps2 - the second set of format parameters to be tested for equality
    
    Returns:
    
    true if the specified sets of format parameters are equal; false, otherwise
  - formatParametersMatch
```
public boolean formatParametersMatch(Map<String,String> fmtps)
```
    Determines whether the format parameters of this MediaFormat match a specific set of format parameters.
    VideoMediaFormat reflects the fact that the packetization-mode format parameter distinguishes H.264 payload types.
    
    Specified by:
    
    formatParametersMatch in interface MediaFormat
    
    Overrides:
