[Live-devel] about the rtp payload for mpa

[flying5yue at sina.com]

 my dear developers of live555:
    I have some questions about the rtp payload for mpa(type is 14) when i use testOnDemandRTSPServer to stream mp3 file.When i capture packet via Wireshark(an network capture tools), on the rtp layer, the payload of the rtp packet is composed of audio frames.It strongly trouble me thatthe composed way. Sometimes, 3 or 4 auido frames are involved and the total length is nearly the MTU(1350Bytes).But sometimes, only 2 audioframes are involved and the total length is far below the MTU, and i think next audio frame can be involved because there is enough space.
    Could you tell me the composed way of the rtp payload for audio frames, please? Where can i find the composed code in Live555 code?
 
             Sincerely!
             Yours pei liu.
