First of all, this method is really very cow, it is better to ingenious: In this app to do foodie, because we need to add a button on the UITableViewCell, when you click on this button to start playing audio (while the button status changed to selected), these processing is OK, But now the problem is that when the audio playback is complete, a proxy method is triggered (that is, telling the

Based on the analysis of the FLV format in the previous article, the FLV format includes file header and file body. Therefore, you can define file header and previous tag size #0 as follows: Const static unsigned char flvfilehdr [] = {0x46, 0x4c, 0x56, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0x00}; The file body consists of the tag header and tag data. Therefore, the tag header can be defined as follows: Unsigned char flvtaghdr [] = {0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0x00}; Note:

[Concept] The PCM (Pulse Code Modulation) Audio Encoding format is also calledPulse Coding Modulation. It is to convert analog signals such as sound into a symbolic pulse column, and then store records. Principle] A continuous analog signal with continuous values is transformed into a discrete time. The Discrete digital signal is then transmitted in the channel. pulse coding modulation is the process of first sampling the analog signal, then quantify

The first three articles have explained in detail how to convert the WAV audio format to the FLV format. This article describes how to convert the last part, first, the AMR is converted into WAV format, and then the WAV format is encapsulated FLV format.
