Today, say what netizens care about about live software development!

Live software development

First, have their own software technical team:


If you want to develop live video software, you have to have at least your own technical team.


Have a block of their own office space and basic development equipment (computers, mobile phones) and so on.


Second, the positioning of software products:


1, determine the function of the software:


The basic functions of the software are: multi-channel login/payment/share, live shooting, private messages, comments, attention, multi-category list, sending gifts, red envelopes, a variety of room settings, beauty and other functions. As for short video, mall and other functions can be selectively developed.


2, determine the UI page:


UI interface is written with code, some with a picture on, a good UI interface smooth, beautiful, small memory consumption.

4, determine the streaming media protocol:


If you choose to do WeChat side small program live, you can choose HLS, if it is APP can choose RTMP protocol, the two protocols have their own advantages, according to product positioning to choose.


Third, live software development and system debugging:


Software development is how difficult not to say, just say system debugging, is now popular mobile phone models are a variety of different manufacturers of different systems of different hardware conditions of each model to be adapted, the process is boring and painful.


Fourth, the third party docking:


After the video broadcast software development, but also with the three parties to achieve some of the services we can not independently develop, such as calling map positioning, such as more advanced beauty services


V. Prepare for the shelf.


Live app software delivery will be completed and will be available on the market for applications such as Android or Apple, depending on product needs.


If there is a small partner who is not clear in the comments area message, like, follow plus forwarding. All right, that's it this time. Goodbye, friends!

Live APP software development process, functions and solutions to technical difficulties

The development of live broadcast APP is like building a building, it needs a solid foundation. Only when the foundation is stable enough, the house can be higher and safer. Similarly, the underlying construction technology of the live broadcast APP is also related to the success or failure of the live broadcast APP. The underlying construction technologies of the live APP mainly include servers, content distribution systems, recording and broadcasting systems, online transcoding systems, user authentication systems, billing systems, payment order settlement systems, and content review systems.1. Server system.In fact, this part is the live streaming media server system, which mainly realizes the data transmission function of live broadcasting. Its performance and stability are directly related to the stability and operating costs of the core live broadcast business platform. Generally speaking, a streaming media server system that can run normally can achieve stand-alone support for 5,000 concurrent online users, and has high resource utilization efficiency.2. Content distribution system.Regarding content distribution, we need to talk about CDNs. It can automatically distribute live content among multiple node servers, so that the whole network can be played, and mobile terminal users can automatically select the nearest service node to accept the published content. If you want to develop a live broadcast software business nationwide, you need to find a service provider with nationwide coverage to ensure the normal progress of the live broadcast business. I don't need to say much about the importance of CDNs.3. Recording and broadcasting system.This part is relatively easy to achieve, but requires more effort to achieve a higher standard. But for an operator-level service platform, if there is no guarantee of stability and performance, you will find that the operating cost will be higher and higher, the efficiency will be lower and lower, and ultimately it will be due to poor user experience.4. Online transcoding system.In the daily format conversion process, we often find that when converting 1080p high-definition programs, using a host with an Intel 7 processor to process it is very expensive, and the transcoding speed is very slow. More appropriate is an operating platform with thousands of users that can stream live simultaneously. Therefore, we must find a more reasonable solution, not only to achieve higher transcoding efficiency, but also to reasonably control the cost to meet the needs of platform operations.5. User authentication system and billing, payment and order settlement system.With the strengthening of the state's supervision of the live broadcast industry, the platform should provide users with a real and reliable authority control mechanism. No one can post illegal or illegal content in the name of a third party. All aspects of live broadcast operation will interact with the flow of funds, such as the online income of the anchor, the settlement of funds between the anchor and the platform, and the recharge and consumption records of users. This is at the heart of business support systems and requires accurate data.6. Content review system.Due to the increasingly stringent content requirements for live streaming applications, it is necessary to manage and critically review the establishment of live streaming applications. Now it's live nationwide, and everyone can play it, so it's hard to rely on manual audits. The data is too big. Preliminary identification of content is required using special techniques, which saves labor costs.The live streaming industry is now diversifying. Whether it is live broadcast APP development or one-to-one live broadcast APP development, the underlying construction technology is required, which is an important part of live broadcast APP development. The above are the important details of the underlying construction technology, I hope to help everyone.

Im instant messaging development: live chat message distribution technology for millions of people

With the popularity of live broadcast applications, especially the concept of live broadcast with goods, the live broadcast scene of large users has been normalized.The real-time interaction in the live broadcast room of large users is very frequent, which is embodied in real-time information such as various user chats, barrages, gifts, thumbs, bans, and system notifications.With such a large amount of real-time information, how to handle distribution will not break the server, and will not make the application frantically refresh and get stuck on the client (without affecting the user experience), which obviously requires special technical means and implementation strategies to deal with.In fact, the real-time message distribution of the live room is technically the same as the traditional online chat room concept, but in the traditional Internet age, the number of online users of the chat room will not be so large. Although orders of magnitude different, the technical models are fully applicable.Let's take the example of a live broadcast room watched by millions of people to see what technical challenges need to be faced.1) There will be waves of news peaks in the live broadcast, such as the refreshed news in the live broadcast, that is, a large number of real-time news sent by a large number of users at the same time. Generally speaking, the content of such refresh news is basically the same. If all the information is displayed on the client, the client is likely to be stuck, delayed, etc., which seriously affects the user experience.2) In the case of a large number of messages, if each message on the server is stored for a long time, it will cause the service cache to proliferate, and the memory will become a performance bottleneck.3) In other scenarios, such as the notification message or system notification after the operation of the room administrator of the live room. Generally, this type of message is more important. How to prioritize its arrival rate.Based on these challenges, our services need to be optimized according to business scenarios.The main services are briefly described below.1) Live room service:The main function is to cache the basic information of the live room. Including user list, banned/banned relationship, whitelisted users, etc.2) News Service:The main function is to cache the user relationship information and message queue information that the node needs to process.Specifically, it's the following two big things.User relationship synchronization in the live broadcast room:A) Members actively join and exit: the live broadcast room service is synchronized to ==> message service;b) When it is found that the user is offline: the message service is synchronized to ==> the live room service.Send a message:a) After the live room service passes the necessary verification, broadcast the message to the message service;b) The live studio service does not cache the message content.3) Zk (ie Zookeeper):The main function is to register all service instances to ZK, and use the data for drop point calculation when circulating between services.Specifically:a) Live room service: place according to the live room ID;b) Message service: according to the user ID placement.4) Redis:Mainly used for secondary cache and backup of memory data when service is updated (restarted).Our message distribution process is mainly as follows:1) User A sends a message in the live broadcast room, which is first processed by the live broadcast room service;2) The live room service synchronizes the message to each message service node;3) The message service sends a notification to all members cached by this node;4) As shown in the above figure, the message service-1 will send a notification to user B.In addition, due to the large amount of messages, we have a notification merging mechanism in the distribution process, and the notification merging mechanism mainly refers to the above step 3.The principle of the notification merge mechanism in step 3 above is as follows:a) Add all members to the queue to be notified (if any, update the notification time);b) Issue the thread, and obtain the queue to be notified by rotation training;c) Notify users in the queue.Through the notification merging mechanism, we can ensure that the thread only sends one notification to the same user, that is, multiple messages are combined into a notification, which effectively improves the performance of the server and reduces the network consumption of the client and the server.Our message extraction process is mainly as follows:1) After receiving the notification, user B will send a pull message request to the server;2) The request will be processed by the message service-1 node;3) Message service-1 will return the message list from the message queue according to the timestamp of the last message transmitted by the client;4) User B gets a new message.For users of the live studio, many messages do not actually have much practical significance, such as a large number of repeated refresh messages and dynamic notifications. In order to improve user experience, such messages can be strategically discarded (this is the biggest difference from real-time chat messages in IM, which is not allowed to be lost).PS: The discarding strategy of message distribution in the live broadcast room, combined with the notification merge mechanism in the section, can stabilize a large number of messages in the direct room and distribute it smoothly.Our discard strategy mainly consists of the following three parts:1) Uplink rate limit control (drop) strategy;2) Downlink speed limit control (drop) strategy;3) Important message anti-drop strategy.Let's explain them one by one.1) Uplink rate limit control (drop) strategy:For uplink speed limit control, the default is 200 pieces/second, which can be adjusted according to business needs. Messages sent after the rate limit is reached will be discarded in the live broadcast room and will no longer be synchronized with each message service node.2) Downlink rate limit control (drop) strategy:For the downlink rate limit control, that is, the control of the message ring queue length (see 5.2 the detailed logic diagram of extracting messages during the message extraction process), the oldest messages will be eliminated and discarded after reaching the maximum value.After each notification, the server will mark the user as pulling, and after the user actually pulls the message, the mark will be removed.The function of pulling the mark: For example, if the user has a pull mark when a new message is generated, if the notification is not sent within 2 seconds from the set mark time (reduce customer pressure, discard the notification without discarding the message), continue to send the notification for more than 2 seconds (continuously Multiple notifications trigger the user kick policy, which will not be repeated here).Therefore, whether a message is dropped depends on the client's ingestion speed (which is affected by client performance and network), and the client does not drop messages.3) Important message anti-drop strategy:As mentioned above: in the live room scenario, some messages must have a higher priority and cannot be discarded.For example: a notification message or system notification after the operation of the room administrator of the live broadcast room.For this scenario: we set up the concept of message whitelist and message priority to ensure that it is not discarded. As shown in the figure at the beginning of this section, there can be multiple message ring queues, and the separation of messages from ordinary live broadcasts ensures that important messages are not discarded.
