Tencent audio and video service experience

explain :

experience

            To say , Tencent audio and video I learned from 2015 It's been in use since , At that time, it was from qavsdk1.01 edition , There were a lot of mistakes in the first few years , After a few years, there are still a lot of mistakes , I'm sorry to charge . At first, it was called interactive live broadcast , Later, I got a free broadcast , Follow your heart （ilivesdk） Namely qavsdk Package enhanced version of . until 2019 Tencent made major changes in audio and video in , Name real-time audio and video trtc, This is a stable and perfect version . Because customer service frequently requires upgrades , From qavsdk Upgrade to trtcsdk,trtcsdk Than before qavsdk Simplified too much , Before, I needed to understand dozens of documents , Now you can complete the basic functions by reading a few files , Of course, I want to realize complex functions , It's impossible not to pull the code . Later on trtc Start to melt tim, Often as tim Part of the .

As a user of Tencent audio and video , What I admire is , Tencent team is quite persistent , First of all, we should know that Tencent audio and video and audio and video on wechat are two different things , What they just started to do was terrible , There are all kinds of problems in the customer service group all day , In this case, it lasted for several years , No money, pure investment , from 2015 Achieve 2019 It's only in the year of , It can be seen that the stall is not generally large . This is not easy for large and small companies eager for quick success and instant benefits in the market .

The question of cost ：

            Used to be a white mouse , But it also wasted traffic and functions for several years .

            Even later , Tencent audio and video costs are not high , Whether live broadcast or video storage , As long as the limit is not exceeded , The cost is very low .

Technical support ：

            When a white mouse in the early stage , Tencent's attitude towards customer service and technical support is quite good , If you have any questions, please reply soon , Answer patiently , No bill of lading at all .

            Later, it's different when it's bigger , Most of the time, asking questions is waiting for the bill of lading , The special point of the problem is to wait for the next version or nothing .

            The reason may be , Tencent's audio and video service documents are now complete , It is estimated that most of the problems have been sorted out , Most of them think of what you think .

Development issues

            Just trtc and tim sdk Use , There are still many problems to be solved in practical application ,demo Although many examples have been done , But it is not always matched to the business , It still takes a lot of work .

Compatibility

            Personally, I think their compatibility is very good , Use a long time ago qavsdk, If you insist on not upgrading, you can still use .

The quality of audio and video

            Tencent cloud now has many functions , Maybe I have money , The stall is very big , Some functions are pretty good , Most of them are still inferior to professional companies .

            But Tencent audio and video , Personally, I think it is a feasible application scheme . Do some video intercom , meeting , Access IPC Monitoring and other functions , And if the function requirements are simple , There is no problem in using , It's not bad , Less investment and simple use .

The composition of each version

The following pictures are on their official website , Simply pick a little , See the official website for details .

Qav sdk Interactive live broadcast

Early Tencent audio and video version , It may not be found now

Node graph

Message flow

In this version , Bypass messages use their own , Not used tim, Basically, it's Broadcasting , Storage , Forward these functions

​​​​​​

  The interaction process of the client

​​​​​​

Tencent real time audio and video TRTC

At this stage , The inner lines are not easy to see , More functions , And start to cohere , The interface is also simplified again . The user can only see what he needs to see , The document also looks much simpler .

Technical level

The interaction process of the client

With web App Take video communication between as an example

​​​​​​

As for the mobile end ,PC The end process may be a little more complicated , Handle initialization , Room management , User management , There is basically no problem with these processes of session management , and Demo Most of them have been done , Only special treatment is needed .

Bypass the live broadcast process

From this open process, we can see , Real time audio and video involve multiple modules , It provides basic services for expansion , Of course, it may involve additional costs . People can press the flow , Charged by storage .

summary ：

I don't know because they did so well , Or is it just because you're using , It's always a matter of looking at flowers in the fog , Used so long , I really can't say anything clearly , I don't know where to start . If you just use , This sdk It's too simple , And the use will be more and more simple , Other aspects are really

There's nothing to say .
