Reprint please the head source link and the tail two-dimensional code together reprint, this article from countercurrent fish yuiop:http://blog.csdn.net/hejjunlin/article/details/52629598Foreword: The OMX event callback is introduced in the previous article, starting from today, go into the OpenMAX frame of codec part. Look at today's agenda as follows: A picture review audio and video synchronization A picture of the location of OpenMAX

The first four articles, respectively, introduced the basic knowledge of audio development, how to capture a frame of audio, how to play a frame of audio, how to store and parse WAV file, it is suggested that interested small partners to read, this article focuses on how to encode and decode a frame of audio data.1. Android's official Mediacodec APIFirst, let's look at the official Android audio codec API, the Mediacodec class, which was introduced in

The Code is as follows: /** Template class that registers itself (in the constructor) into a linked-list and provides a function-pointer. This can be used to auto-register a se

In "Let WEBRTC support H264 codec" I provide a priority to use the H264 codec thinking. We can verify it on the browser side. There are three ways to verify: In JS print SDP view Chrome's log chrome_debug.log (see Open Chrome Log) Grab bag using webrtc-internals The first three kinds are no longer introduced, we look at the webrtc-internals.

First of all we need to understand what CODEC means. It is Coder + Decoder = Codec, which is the encoder decoder. That is, the encoder is also the decoder.Website address: http://commons.apache.org/proper/commons-codec/Apache Commons Codec (TM) software provides implementations of common encoders and decoders such as B
