Mobile phone audio and video Development Kit, audio and video Development Kit Overview:The mobile video Development Kit is intended for integration or software developers. It is used for mobile video-related product development and system integration.The Development Kit provides functions such as audio and video collection, encoding, compression, and

Explanation of iOS network audio playback and ios audio playback In daily iOS development, we usually encounter media playback problems. XCode provides us with a powerful AVFoundation framework and MediaPlayer framework. AVAudioPlayer in the AVFoundation framework is mainly used to play local audio or network audio. H

In scenes where audio and video are re-encoded and need to be synchronized, there are several basic principles to follow (otherwise the audio and video will be stuck and not smooth.) With audio AAC encoding frequency 44.1k, video H264 encode 25 frame rate for example): 1. Ensure that the audio and video frame arrival

Android audio recording and Android audio recordingMediaRecorder class detailsMobile phones generally have microphones and cameras, and Android systems can use these hardware to record audio and video.Android provides a MediaRecorder class to support audio and video recording. This class is also very simple to use. Let

Problem You want to have a method for playing sound quickly. Solution In xna3.0, you can directly load and play sounds from xNa without loading them using xact. Although this method removes some advanced xact functions, it makes playing sound very easy. Working Principle First, add a sound file to the project. The method is the same as adding an image to the project. For more information, see tutorial 3-1. The simplest solution is to drag a .wav file to the content folder of the solution. A

PCM file: Analog audio signal is directly formed by the analog-to-digital conversion (A/D transform) binary sequence, the file has no additional file header and file end flag. The Convert tool in Windows can convert PCM audio format files into Microsoft WAV format files. Digitizing the audio is actually about digitizing the sound. The most common way is to modula

Currently, the following device interfaces are supported in Android4.2 (defined in AudioFlinger. cpp ): * audio_interfaces[] = AUDIO_HARDWARE_MODULE_ID_PRIMARY, AUDIO_HARDWARE_MODULE_ID_A2DP, AUDIO_HARDWARE_MODULE_ID_USB, }; Constants in the array are also defined in/hardware/libhardware/include/audio. h: AUDIO_HARDWARE_MODULE_ID_PRIMARY "primary" AUDIO_HARDWARE_MODULE_ID_A2DP "a2dp" AUDIO_HARDWARE_MODULE_ID_USB "usb" During initiali

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:

For the cool dog software users to detailed analysis to share the cool dog audio device settings tutorial. Tutorial Sharing: Audio output: The output type provides both DirectSound and Microsoft Sound Mapper types, DirectSound efficient, while Microsoft Sound Mapper compatibility is better; the default is DirectSound output type, and the default setting is recommended. All right, the above

[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. The key part of this article is the part in the while loop. The other part can be skipped. The function d_if_decode (St, serial, synth16, _ good_frame ); the function is to encode a frame of AMR data
