JQuery1.3 has been released. You can view details on the official jQuery blog. JQuery is three years old! If you want to update the Validation plug-in, make sure that you update the Validation plug-in to version 1.5.1 at the same time. It is compatible with both version 1.2.6 and 1.3. Major updates include:
1. Use the validHandler parameter to replace a form event that must be bound to useless before, the specific demo can access marketo (http://jque
If you are going to update, make sure that you also update the validation plugin validation Plugin to version 1.5.1, which is compatible with both 1.2.6 and 1.3 versions. The main updates include:1.

Real Time Streaming Protocol or RTSP (Real-Time Streaming Protocol) is an application layer protocol jointly proposed by real network and Netscape to effectively transmit streaming media data over an IP network. RTSP provides an extensible framework that enables controllable and on-demand transmission of real-time data, such as audio and video files. The source data can include on-site data feedback and stored files. RTSP provides control for streaming media such as pause and fast forward, but i

to generate multiple bitstreams with different bit rates and image sizes. Then, you can select the most suitable bitstream for transmission. The generated code streams need to be further packaged into packets of specific network transmission protocols for network transmission. Because many networks do not guarantee that the transmitted data can be received in a timely and completely correct manner, the transmitted data packets may need to be protected by forward correction encoding (FEC). After
Vxworks5.5 can only create a static library (. a). After vxworks6.0, the dynamic link library (. So) function is added to facilitate multi-process use of dynamic libraries. This article inherits the consistent style of Win32 and Linux programming, uses a simple dynamic library generation step, and writes the RTP program for testing. This gives you a preliminary understanding of the powerful functions of vxworks6.6, at the same time, we also noticed th

If the power of a person is limited, the power of the network is infinite. The purpose of studying h264 is to customize a streaming media player to play videos in real time.
Fortunately, there are a lot of online cool people standing on the shoulders of giants, and the pressure will be much lower.
Overall Player Design Scheme
Generally, the overall player design includes three stages:1) obtain media data2) decoding Audio and Video Streaming Media3) display decoded media data to the user

Finally, also when you are free to manipulate character activities, if you hold down the CTRL key to move, you can ignore the map tile's traffic, even on the inaccessible components can also move freely. 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

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:

The above is the workflow of mp4live.

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

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

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

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
