3 questions about CDN video streaming and how to solve them
Currently, video content accounts for only 70% of all Internet traffic (and is still rising), so video streaming has become more important than ever. Currently, most content is managed by content delivery networks (CDN). However, when it comes to CDN video streaming of real-time content, there are many disadvantages.

5 reasons why H.265 real-time streaming is not practical
There are many codecs currently in use, including VP8/9, H.264 (AVC), H.265 (HEVC) and AV1. In previous articles, we introduced AV1 and VP8/9, so this article focuses on H.265. Of course, the most important thing is which codec is most effective. Therefore, we will introduce how H.264 is currently a more effective choice for low-latency real-time streaming.

Audio and video technology
The technology behind Didi AR real-world navigation
In large indoor places such as airports, shopping malls, and railway stations, GPS signals are unstable, large indoor areas, complicated routes, and difficult for users to determine directions, which pose great challenges for passengers who issue orders in large places to find a pick-up point. , The user urgently needs a guidance function that is simple to operate and interactive. This article describes the Didi AR real-world navigation products developed using 3D reconstruction technology, sensor computing technology and augmented reality (AR) technology, and introduces the difficulties, challenges and solutions encountered in the development process.

AI intelligence
Video call under 5KB/sec bandwidth?
NVIDIA MAXINE AI cloud computing-based video streaming platform
In remote areas, subway stations or elevators, mobile phone bandwidth will inevitably drop to single digits. In this case, very often webpages are stuck, even WeChat cannot be connected, and the video call will be interrupted. In fact, with the development of deep learning technology, AI-assisted video coding technology makes video calls in the above-mentioned situations possible. Recently, NVIDIA has proposed a video streaming platform based on AI cloud computing, which greatly reduces the video call stream while ensuring the high-quality reconstruction of video images.

What I learned while pursuing a master's degree in computer vision and machine learning
This article introduces my experience and course content, but I believe that the courses of other universities will not be much different from what I have studied. Therefore, readers can use this article as a window to understand the master's degree courses and content of machine learning and computer vision.

Hand rub a Webpack Plugin for TinyPng compressed pictures
If you always pay attention to the topic of performance optimization, you may find that no matter how best to optimize the code, it is not enough to compress an image once. Therefore, compressing pictures has become the most common operation in performance optimization. Whether it is manually compressing pictures or automatically compressing pictures, it must be done during the project development process.
