how to achieve can look at my previous article (audio transmission of the jitter buffer design and implementation). Here's how to calculate the network delay statistics (OPTBUFLEVEL), which is one of the difficulties. Assuming 20Ms per pack, ideally every 20Ms receives a voice packet from the Web. The reality is that the network has delayed packet jitter, resulting in not receiving a packet every 20Ms, but sometimes dozens of or even 100 milliseconds to receive a package, sometimes 20Ms rece

The simplest example of a variable length parameter is printf. Sometimes it can be pirntf ("% d", a) or printf ("% d", a, ); the first parameter is two parameters, and the last parameter is three parameters. It is done using similar syntax. _ Android_log_print is the function provided by android to p

variable of PV_Wav_Parser. The PVMFWAVFFParserNode class is generated through the CreatePVMFWAVFFParserNode () member function of PVMFWAVFFParserNodeFactory. The CreatePVMFWAVFFParserNode () function is registered to the vector of Oscl_Vector in the PVPlayerNodeRegistry: PVPlayerNodeRegistry () Class constructor through the PVPlayerNodeInfo class. In this constructor, AMR, mp3 and other nodes are also registered. It can be seen from the above that th

Java File Format Conversion Tool Sometimes a file is correctly formatted and may not be correctly played in some cases. here we can use a java class to help us convert the file format to a correct one. File source = new File (filepath); int index = amr. lastIndexOf (".

. In mobile Softswitch, MGW uses mobile-specific AMR voice encoding methods, MGW should support G.711, G.723, or G.729 when interworking with the fixed network. In terms of broadband Softswitch, both fixed and mobile Softswitch, call control protocols adopt the SIP protocol. The SIP Protocol provides a unified end-to-end dialog mechanism for services running on IP addresses, regardless of the bearer network. Therefore, SIP-based applications can be us
