you brush your teeth, such as a long time of sudden cold or sudden hot stimulation, affects the life of the teeth. Misunderstanding 3: select a big toothbrush In fact, only a toothbrush with a small brush head can be flexibly rotated in the mouth. In addition, the brush hair arrangement must be reasonable, generally 2-3 rows, easy to clean teeth and brush teeth after the toothbrush itself cleaning. Choose high quality Nylon Silk brush, fine and elastic. The top of the brush should also be cir

Live broadcasting: The existing Isma method. The process is as follows: Video collection-> video encoding-> RTP packaging-> UDP multicast; Audio collection-> Audio Encoding-> RTP packaging-> UDP multicast; The above is the workflow of mp4live. Live Video: mpeg ts stream mode. The process is as follows: Video collection --> video encoding --> Audio collection> Audio Encoding> TS packaging>

I think the last time I wrote a blog was a few years ago. When I was still at school, my blog was just coming out. There are many reasons why I did not write many edits. The most important reason is that I graduated from college. At that time, I was exhausted by my work, so I had to write my blog. Some time ago, when it was very empty, there was some time to write, but it was the Qzone of QQ, And it was mainly about some things of life. The main reason for re-opening a blog is that during this p

3.2.16 RTPPacketBuilder ------------------------------------------------------------------------- Header file: rtppacketbuilder. h This class can be used to construct RTP data packets, which is more advanced than RTPPacket: it can generate SSRC identifiers, tracking timestamps, serial numbers, and so on. The interface is as follows: Int Init (size_t maxpacksize) ----- Initialize the builder so that the allowed package size is smaller than maxpack. Voi

Correspondingly, a video is played at a fixed interval, and a complete frame of video data conforms to the CIF, QCIF, or SQCIF format.3 VoIP media encapsulation requirementsAfter the original media stream is encoded, It is segmented into segments according to certain rules, and then

follows: RTSP comprehension and Examples RTSP is a Real Time Streaming Protocol. According to my understanding, it is a streaming media control protocol, the encoding types and addresses of both parties, and the control over stream media (play, pause, record ). do not mix with the RTCP protocol. RTCP is used to control RTP. The following describes several methods of RTSP to describe the protocol.1: OptionsThe client usually sends the server to ask ab

, and other parameters. The initialization information is not directly applied to devices, but stored in the structure type parameter pctx of an encoding parameter. Then, you can use the following code to set parameters, that is, to apply the parameters to actual devices.IOCTL (pctx-> hopen, cmd_init, mfc_args );The encoding part is implemented using the next line of code.Ioetl (pctx-> hopen, cmd_exe, mfc_args );After encoding, you can use the function to obtain the memory address of the encod

Transferred from: http://tieba.baidu.com/p/2138076570Abstract: In order to solve the problem of audio and video synchronization caused by delay, jitter and network transmission conditions, a new audio and video synchronization scheme is designed and implemented to adapt to different network conditions. Using the audio and video coding technology, AMR-WB and H. e have the characteristics of rate selectable in complex network environment, combine RTP ti

signal.For out-of-band detection, a DTMF signal is carried through the info method of the SIP signaling. There is no uniform implementation standard, and the DTMF keys are identified by the signal field in the Sipinfo package with the Cisco sipinfo standard . Note that when DTMF is "*" The different standards implement the corresponding signal=* or signal=10. The advantage of Sipinfo is that it does not affect the transmission of RTP packets, but b

You can use this when the game map is large and you only want to get to the point where the plot is triggered, or if you accidentally have an unacceptable block of traffic. But if it is th
