Recently, Apple WWDC has repeatedly mentioned the relevant content related to H.265, so many non-decoding fields have begun to care about this technology. Most people are most concerned about how this technology will affect the future audio and video fields, as well as they do not change.
Today, the details related to the decoding code do not have to disclose them to just say it is related to the application.
First we have to have some understanding of the background of H.265

What is the H.265 encoding?
Reference Wikipedia: High Efficiency Video Coding, referred to as HEVC) is a video compression standard that is considered to be a successor of the ITU-T H.264 / MPEG-4 AVC standard. HEVC is considered not only to improve video quality, but also to reach the compression ratio of the H.264 / MPEG-4 AVC (equivalent to the same picture quality reduction to 50%), support 4K resolution or even a super HD TV. (UHDTV), the highest resolution can reach 8192 × 4320 (8k resolution).
Simply put, H.265 is a new video compression standard. The core value is to transmit higher quality network videos under limited bandwidth, and only half of the left and right bandwidth can play the same quality video. This means that the same bandwidth cost can enjoy a higher quality audio and video service.
H.265 What is the meaning of live broadcast and on-demand platform?
Due to the characteristics of H.265 high compression ratios, most live broadcast and on-demand platforms are very concerned about their development progress. If H.265 can be widely used in its own business, it can save costs, improve user experience, and effectively and competitively opened the gap in the market.
Even if H.265 has an absolute advantage, the mainstream code compression standard on the market is still H.264, what is going on?

First of all, this is because H.265 has a higher encoding complexity, and the power consumption is larger, and it takes longer.
In fact, this is also very understanding, saying more about: You pinch a sponge, if you want to press smaller, it will take a bigger strength to pinch. Similarly, you want to compress the compression ratio when encoding compression, then compressed algorithms are more complicated, the requirements for device performance are higher, and the power consumption in unit time is greater.
Second, the increase in encoding complexity of H.265 makes it more complicated. In terms of current, most players are not specifically compatible with H.265.
Finally, it is necessary to mention that the browser is not supported by the H.265 decoding. How many audio and video customers are meant to share access to the propagation to get a new user, it is blocked.
This is not a simple technical issue, this is a standard problem. At present, all mainstream browsers on the market do not support H.265 decoding. In other words, your APP recording or live streaming video cannot be viewed by sharing to a circle of friends, or watch it on the web.
Is there a solution?
For H.265 layout, Qi Niu Yun has already walked in front
Above we said, H.265's codec is very performance. From hardware, it is possible to make the GPU to do things, that is, you can hardly edit it. In fact, Apple itself supports H.265's hard work, and in subsequent IOS 11, they will open this capacity to all developers. This means that the iOS platform has been in most feet into the era of H.265.
But for those live broadcast and on-demand platforms for all ordinary users, only iOS support H.265 is not enough. Everyone opens the door to do business, always can't ask each customer to choose mobile devices in their own wish. Therefore, H.265 must be further popularized to support soft coding, which is to use the CPU to perform H.265 encoding, and the power consumption is controlled within a normal range.
At present, the H.265 program of seven cattle live clouds supports IOS and Android double platform soft coding, and the test results represent the power consumption and the H.264 softcode approximation.
Seven Nile Cloud also provides a server-side transcoding scheme. Simply put, July Niu Yun provides a service of H.265 and H.264. For example, you have recorded a high-definition short video with H.265 and uploaded to the seven Niu Yun. At this time, the server will transfer this short video to a H.264 file, then the user uses the H.265 encoded file in Qi Niu Yun when the Native calls play. When the browser is called, H. 264 encoded files. The real-time mutual transition under live scenes, and the seven Ni Niu Yun also immediately launched a service.
For the player's decoding problem on the H.265, the seven cattle clouds launched a high-performance player that completely self-developed, and made special optimizations for H.265.
H.265 Prospect Prediction
Overall, I think the prospect of H.265 is very clear, and it is only a matter of time. Because it basically has a variety of unique conditions.
The first is: the support of the giants, Apple repeatedly mentioned at least H.265 in WWDC illustrates Apple's attitude. Billions of Apple Equipment in the world will become a factor in H.265.
The second is: the promotion of audio and video companies, because the popularity of H.265 is directly related to the profits related to many audio and video business companies. Imagine, if it is a large number of bands, it is more than 50%, and a large profit is likely to let some live broadcast companies turn loss.
The third is: Since the upgrade update of hardware devices is faster, the performance of hardware such as mobile phone PC will result in a shortcoming of H.265 performance requirements and slowly being overcome.
The fourth is: the upgrade of the rich media, such as the rapid development of the next generation of generations. The amount of information transmitted within the unit bandwidth is higher than that of the traditional media.
The above mentioned high-performance player on H.265 is mentioned above, and the document has been "quietly flowing". Interested small partners pay more attention to seven cattle.
