Creates a MediaFormat either for the specified rtpPayloadType or for the specified encoding, clockRate, channels and set of format parameters. If encoding is known to this MediaFormatFactory, ignores rtpPayloadType and returns a MediaFormat which is either an AudioMediaFormat or a VideoMediaFormat instance. If rtpPayloadType is not MediaFormat.RTP_PAYLOAD_TYPE_UNKNOWN and encoding is null, uses the encoding associated with rtpPayloadType.

Specified by:

createMediaFormat in interface MediaFormatFactory

Parameters:

rtpPayloadType - the RTP payload type to create a MediaFormat for; MediaFormat.RTP_PAYLOAD_TYPE_UNKNOWN if encoding is not null. If rtpPayloadType is not MediaFormat#RTP_PAYLOAD_TYPE_UNKNOWN and encoding is not null, rtpPayloadType is ignored

encoding - the well-known encoding (name) to create a MediaFormat for; null

clockRate - the clock rate in Hz to create a MediaFormat for

frameRate - the frame rate in number of frames per second to create a MediaFormat for

channels - the number of available channels (1 for mono, 2 for stereo) if it makes sense for the MediaFormat with the specified encoding; otherwise, ignored

formatParams - any codec specific parameters which have been received via SIP/SDP or XMPP/Jingle

advancedParams - any parameters which have been received via SIP/SDP or XMPP/Jingle

Returns:

a MediaFormat with the specified encoding, clockRate, channels and set of format parameters which is either an AudioMediaFormat or a VideoMediaFormat instance if encoding is known to this MediaFormatFactory; otherwise, null
