| OpalMediaFormat::OpalMediaFormat | ( | OpalMediaFormatInternal * | info = NULL |

Default constructor creates a PCM-16 media format.
| OpalMediaFormat::OpalMediaFormat | ( | const char * | fullName, | |
| const OpalMediaType & | mediaType, | |||
| RTP_DataFrame::PayloadTypes | rtpPayloadType, | |||

| ) |
This form of the constructor will register the full details of the media format into an internal database. This would typically be used as a static global. In fact it would be very dangerous for an instance to use this constructor in any other way, especially local variables.
If the rtpPayloadType is RTP_DataFrame::DynamicBase, then the RTP payload type is actually set to the first unused dynamic RTP payload type that is in the registers set of media formats.
The frameSize parameter indicates that the media format has a maximum size for each data frame, eg G.723.1 frames are no more than 24 bytes long. If zero then there is no intrinsic maximum, eg G.711.
| fullName | Full name of media format |
| mediaType | media type for this format |
| rtpPayloadType | RTP payload type code |

| needsJitter | Indicate format requires a jitter buffer |
| bandwidth | Bandwidth in bits/second |

Construct a media format, searching database for information. This constructor will search through the RegisteredMediaFormats list for the match of the payload type, if found the other information fields are set from the database. If not found then the ancestor string is set to the empty string.
Note it is impossible to determine the order of registration so this should not be relied on.
| rtpPayloadType | RTP payload type code |
| clockRate | clock rate |
| rtpEncodingName | RTP payload type name |
| protocol | valid protocol (if NULL, then all) |
| OpalMediaFormat::OpalMediaFormat | ( | const char * | wildcard | ) |
Construct a media format, searching database for information. This constructor will search through the RegisteredMediaFormats list for the wildcard match of the parameter string, if found the other information fields are set from the database. If not found then the ancestor string is set to the empty string.
The wildcard string is a simple substring match using the '*' character. For example: "G.711*" would match the first of "G.711-uLaw-64k" and "G.711-ALaw-64k" to have been registered.
Note it is impossible to determine the order of registration so this should not be relied on.
