Audio Stream (proportion of redundant data):
Let's take a brief look at the structure of the ADTS header:
1) The ADTS header is at the beginning of each AAC frame and is typically 7 bytes long (or 9 bytes, not seen).
2) The length of each AAC frame is fixed to 1024 sample (can be 1024*n, have not seen n>1 case).
3) Most of the information in the ADTS header is useless, only the sample rate (4bit), the numbe
. HTTP Live Streaming
HTTP Live streaming is an HTTP-based streaming media transport protocol proposed by Apple. It cuts an entire audio and video stream into a small audio and video stream that can be downloaded by HTTP and generates a playlist (m3u8), where the client only needs to get a m3u8 playlist of resources t

When developing a multimedia application or game application, you need to use the volume control key to set the volume of the program. There are multiple audio streams in the Android system. The setVolumeControlStream (int streamType) function in the Activity can be used to set the audio streams controlled by the volume control key in the Activity, which is generally set in the onCreate function.

Complexity is inevitable and will only increase over time. Therefore, when adding features, you must set aside time for restructuring and code simplification. Do not worry about performance before encountering problems. The iPhone is very strong and you may never encounter unexpected performance problems.

speex encoding, they are fixed and invalid data in the Protocol. The encoding sampling rate is 16 kHz, single channel, 16 bit/sample.
The remaining data is the audio frame data, which can be a set of multiple frames, depending on the framesperpacket mentioned above. The default value in Flex is 2, so each audio package has two frames of data. Note: When the VAD function is enabled, the two data frames can

Fluidization is a process in which we only need to maintain a small chunk of memory in memory to play audio files. This allows us to use very large audio files as background music without taking up a lot of memory. When we stream an audio file, the audio data is read from a
3. Dynamic Distribution and implementation of cache areas.
Based on this fact, the audio data is much smaller than the video data. Therefore, the audio buffer and the video buffer are managed separately. According to statistics, the RTP data packet size of the same media stream is similar. For example, the audio size i
