Ⅲ How much does it cost to develop a live video APP

How much does it cost to develop a live video APP

First of all, I want to ask you a basic question. Customized development, source code development and template application are the three methods of live broadcast APP development. Which method do you choose? This question is very critical and related to the answer to your question.

Some people say that you should not think about customized development of live broadcast APPs because it is too expensive. Others say that you should never directly use templates for live broadcast APP development. It is too spicy and you should never choose it. In fact, this is all one-sided. Words, in fact, exist to be reasonable. These three development methods all have their own significance, but they are suitable for different people.

1. Customized development

Purely customized development of live broadcast APP source code. Every string of code is typed by programmers. It is very expensive, about 30w, which is certainly unaffordable for ordinary people, but for friends who can make good use of it and achieve greater benefits, this is just a brick on the road to entrepreneurship. The custom development cycle of live broadcast APP is also long, plus the time for testing and modification, so it is not suitable for those who are "anxious".

2. Source code second release

The basic framework and basic functions of the live broadcast APP have been developed. It is also a good choice for people behind to take it back to customize and develop special functions. This source code can It is constantly updated and iterated during the operation process. Since it is produced in a "streamlined production", the market price is usually low, around 70,000. The source code development method is the most cost-effective development method among the three development methods.

3. Template application

The method of applying templates for live broadcast APP development is actually very common, although from a technical point of view, this method is more "spicy" because it cannot be used. For secondary development, any code in the template cannot be changed, and there is no possibility of secondary development. However, due to insufficient budget and hope to build the program first, with the hope of "operation"It is more suitable for entrepreneurs with a "run and try" mentality, but it will be more troublesome during later updates or migrations.

In addition to the live broadcast APP development method, the quality of the source code will also affect the answers to your questions. The quality Low source code will naturally be lower, so how to judge the quality of the source code?

1. Look at the reputation of the developer's other products

2. Look at the maintenance status and update iteratively How many times

3. Check whether the code is clean and whether there are any after-sales measures

4. How much concurrency does the live broadcast APP source code support?

Live broadcast APP development

Low latency, smoothness without lag, excellent interactive experience, no black screen, rich gift system, live broadcast picture clarity...many things will affect the user experience. If you want to solve these problems, you can use the live broadcast APP Don’t be too picky about development costs and operating costs. It is particularly important to find a balance between the two.

IV The top ten domestic digital twin companies

The top ten domestic digital twin companies are as follows:< /p>

1. Yanhua Intelligent (002178)

Yinjiang Technology Co., Ltd. is one of the first companies listed on the GEM in China and is a city brain operation service provider . Yinjiang Technology actively responds to the national strategic deployment of "artificial intelligence" and is committed to the construction, operation and service of urban brains.

The company takes "promoting urban progress and ensuring people's well-being" as its mission, through the Internet of Things and cloud computing , big data, artificial intelligence, blockchain and other technologies to create a cross-domain and cross-regional urban brain data resource exchange and sharing platform for urban management and people's livelihood services, and promote a new wave of urban civilization development.

IV What are the blockchain software development companies?

Based on some characteristics of blockchain technology, the fields of blockchain application are still relatively wide, especially in the financial industry, and others such as medical, Forensic proofs, smart contracts, sharing economy, digital assets and other fields

Each field has related needs that require the development of software systems for further application of blockchain technology

In Tao In my opinion, only a small number of companies currently conduct in-depth research on blockchain technology, and some large companies only conduct application research and development for some internal needs of the company. Few companies like Qi Hengying and Tang Zhongchuang have proposed Qianjian provides blockchain technology application system development

Yingtang Zhongchuang has many solutions for the development of blockchain application software systems. You can refer to one or two for answers

Ⅵ Companies that can provide blockchain services in Beijing

There are companies like this in Beijing, but there are not many at present, because blockchain is special, and only a few companies in China can do it, but not necessarily Large companies, but only those who have actually done blockchain implementation projects, such as Renren Chain.

Ⅶ What are the large-scale domestic blockchain concept stocks?

Domestic large-scale Blockchain concept stocks include: Sifang Jingchuang, Huaying Agriculture, and Hang SengElectronics, Yijian Shares, Gao Weida.

Challenges faced

From the perspective of practical progress, most of the applications of blockchain technology in commercial banks are still being conceived and tested. There is still a long way to go before it can be used in life and production, and it also faces many difficulties in gaining recognition from regulatory authorities and the market. The main ones are:

1. Restricted by current concepts, systems, and laws. The characteristics of decentralization, self-management, and collective maintenance of blockchain have subverted people's production and lifestyle, diluted the concept of state and supervision, and impacted existing legal arrangements. For these, the entire world completely lacks theoretical preparation and institutional discussion. Even for Bitcoin, the most mature blockchain application, different countries have different attitudes, which inevitably hinders the application and development of blockchain technology. There is obviously still a long way to go to solve this kind of problem.

2. At the technical level, blockchain still needs breakthrough progress. Blockchain applications are still in the initial development stage of the laboratory, and there are no mature products that are intuitive and available. Compared with Internet technology, people can use specific applications such as browsers and APPs to browse, transmit, exchange and apply information. However, blockchain obviously lacks such breakthrough applications and faces high technical barriers.
