RTP传输中的负载类型和时间戳 在Jrtplib中好像不需要自己管理时间戳的递增，由库内部管理。但在ORTP中每次数据的发送都需要自己传入时间戳的值，即自己需要每次发完一个RTP包后，累加时间戳增量，不是很方便，这就需要自己对RTP的时间戳有比较深刻地理解-Type of the RTP transmission of load and time stamp in Jrtplib seems do not need to manage its own timestamp increment by the library internal management. ORTP in each data sent their incoming timestamp value that they need each finished an RTP packet, the cumulative timestamp increment, not very convenient, which requires its own RTP timestamp a more profound understanding of
