number is also used to determine the correct location of a packet, for example, without sequentially decoding the packet when the video is decoded. But RTP's original design was designed to meet the needs of multi-participant multimedia conferencing, which was not limited to specialized applications. Storage of continuous data, interactive distributed simulations, dynamic tagging, and control and measurement applications may also be suitable for use with RTP. 1, RTP fixed head structure RTP fix

register value and found that the volume register value did not change at all, but the volume actually changed. At that time, we suspected that our android volume adjustment was not implemented by hardware, but by its own SW mixer mechanism. When I had dinner with vic in the evening, I had a chat about it. status_t AudioFlinger::setMasterVolume(float value){ // check calling permissions if (!settingsAllowed()) { return PERMISSION_DENIED

Thank you!Control Interface The control interface allows the user space application (ALSA-Lib) to access and control multiple switches and sliding controls in the Audio Codec Chip. For mixer (sound mixing), the control interface is particularly important. Starting from ALSA 0.9.x, all mixer oper

guarantee service quality and service quality is provided by RTCP. Application environment of 1.2. RTP RTP is used to transmit real-time data in a unicast or multicast network. They are typically used in a number of situations. (1) Simple multicast audio conferencing. Voice communication is implemented through a multicast address and a pair of ports. One for audio data (RTP) and another for control packs (RTCP). (2) Audio and video conferencing. If both audio and video conferencing are used in

A snd_kcontrol inquiry was written several days ago. This article describes the beginning and end of the kcontrol interface from the kernel source code. In the past few days, we have added some audio control interfaces to Android and used them in combination with alsa_amixer scontents analysis. This is because there are too few materials and many things are self-Understood. If you have any mistakes, please forgive me and point out. The name field is the name identifier, which is very important

The overall Android audio includes the android layer and the underlying ASLA driver. Recently, I started to call the 3G Function and then began to access the android audio architecture. I had some experience debugging the sound card before. However, these functions are relatively simple and basically only need to modify the audio path, that is, modify audio_codec.h, which defines the audio data flow in various circumstances. A struct is defined as follows: Typedef struct audiomixer_tag {Cons

%); background-color: darken($white,50%);} After compilation, we can get a calculated color value: .lgt { color: #1a1a1a; background-color: gray;} For more information about functions, see the SASS official function list.6 mixer mixin simple Mixer The mixer in sass is generally used to solve the problem of large code duplication. For example, you can use a

the design and selection of the stirring device are closely integrated with the stirring operation purpose. Different stirring processes need to be operated by different agitation devices. In the design and selection, the purpose and requirements of the stirring operation should be based on the process, determine the mixer type, motor power, stirring speed, and then select the reductor, Rack, mixing shaft, Shaft Seal and other components.

I 've been working on a Python pygame-based music player in the last few days.
