Tengxun cloud video-on-demand VOD one-stop hosting: farewell slicing, transcoding and bandwidth anxiety "worry-free guide"
In this era of "everything can be videoed", whether you are doing online education, e-commerce with goods, enterprise internal training, or building a pan-entertainment applet, video function has almost become a necessity.
However, for many technical teams, especially the development of small and medium-sized enterprises,
Self-built video servers are often a months-long nightmare ".
You may think that video playback is very simple: buy a server, upload MP4 files, and use one at the front end.
<video>
Isn't it over once the label is hung?
However, the reality will quickly give you a loud slap in the face: users will doubt life if they turn on the video card; The 4K video recorded by the mobile phone directly explodes the server bandwidth. Different browsers and mobile phone models frequently report errors and cannot be played. Not to mention the risk that hard-earned copyright videos will be packed and downloaded by others with crawlers for one second.
The water behind video technology is deeper than imagined. In order not to let enterprises repeat the wheel, Tencent cloud video on demand (Video on Demand, referred to as VOD) gives a very straightforward solution:
One-stop hosting.
Today we will talk in vernacular about how much hair and real money this VOD, which completely encapsulates complex video technology, can save us.
1. self-built video platform, exactly where is the card?
Before dismantling Tengxunyun VOD, let's take a look at what big pits you would step into if you wanted to knock a video system yourself:
Transcoding Inferno: The formats of videos uploaded by users are various (MKV, AVI, MOV, MP4). If it is released intact, many mobile phones will not play at all. You have to set up a transcoding server in the background (for example, FFmpeg) and assign them to the most compatible H.264/MP4 or the more bandwidth-saving H.265. Transcoding extremely consumes CPU, hundreds of users transmit video at the same time, and the server crashes instantly.
Massive storage and high bandwidth: video is the real "space devourer". A 1080P short video can be hundreds of megabytes. What's more, bandwidth. If 1,000 people order online at the same time during the evening peak, the high public network bandwidth bill can directly drag down the start-up company.
"Caton" and "First Frame Delay": If there is no CDN (Content Delivery Network) acceleration, it will take several seconds just to load the rotating circle (first frame) to access the video located in the Shenzhen computer room in the south. Users have long lost patience to close the page.
2. Tencent Cloud VOD: What is the real "one-stop hosting"?
The core logic of Tencent Cloud VOD is very simple:
You are only responsible for two things-"upload" and "play". All the dirty work and complex underlying technologies in the middle are automatically completed by Tengxun Cloud in the cloud.
We can break down its standard workflow into three stages to see how it can be managed in one stop:
1. Cloud intelligent takeover: uploading is worry-free
When the user or your tube
From the moment the manager uploads the video, VOD's intelligent automated workflow (Workflow) starts to work.
It supports direct client upload (front-end SDK), and the video stream directly from the user's mobile phone or browser safely flies into the Tengxun cloud storage bucket,
Do not occupy your own business server bandwidth.
2. Tencent's "housekeeping skills": media processing and speed HD
This is the most hard-core stage of Tencent Cloud VOD. After the video enters the cloud, it will automatically trigger the preset task:
Intelligent transcoding: Automatically slice videos (into M3U8 format) and transcode them into various definitions (Blu-ray, UHD, HD, and SD) to adapt to different network environments.
Top Speed High Definition (TSHD): This is Tencent's own trump card technology. Through AI dynamic semantic analysis, it can intelligently identify where in the video is dynamic (such as a running player in a football game) and where it is static (background lawn). Under the premise of ensuring that the picture quality is not degraded at all and even subjective visual changes are good, the video code rate can be reduced by 30% to 50%!
The same picture quality, which originally required 2M bandwidth to pull, now only needs 1M. This directly helps enterprises cut half of CDN bandwidth traffic charges.
3. Global Accelerated Distribution: The Happiness of Seconds
After transcoding is completed, the video will be automatically pushed to Tengxun Cloud all over the world.
2800 multiple CDN acceleration nodes
Up.
When a user in Harbin clicks play, he visits the local computer room in Harbin, which is only a few kilometers from his home. Coordination
First frame adaptive acceleration
Technology, basically can do "instant broadcast", like watching local video as silky.
3. Live Perspective: What other hidden tricks do VOD have for people to call "really sweet?
As a full stack product, tengxunyun VOD not only solves the problem of "being able to play", but also solves many pain points at the business level:
1. AI intelligent audit (refuse violation, protect rice bowl)
As a video website, what users fear most is to upload videos that violate regulations, involve pornography, politics or violence. If it all depends on manual audit, not only is it inefficient, but once one is missed, the entire App or website will face the top penalty of being blocked from the shelf.
VOD has built-in powerful
Audio and video AI audit
. After the video is uploaded, the AI will automatically capture the picture in seconds, extract audio speech (ASR) and recognize the text in the video (OCR). Once found suspected violations of content, immediately automatically intercept and notify the administrator. This is the "life renewal artifact" of the operation team in today's increasingly strict compliance ".
2. Hard-core anti-theft chain and video encryption (to protect intellectual property)
For businesses such as online education and paid courses, the most hated thing is that buyers secretly record videos or download them with scripts, and then resell them at low prices.
The traditional anti-theft chain can only prevent others from copying links (stolen brush flow
Quantity), can't prevent others from downloading files directly. Tencent Cloud VOD provides
Commercial Digital Rights Management (DRM)
and
Private encryption (HLS encryption)
. The video file is cut into numerous small fragments with high-intensity encryption in the cloud, and the front end is decrypted with a dedicated player during playback. Even if the hacker gets the file link, the download is just a bunch of garbled codes that cannot be played.
3. One-click generation of exclusive player
Many front-end students work overtime every day to correct bugs in order to adapt to the compatibility of various browser players for Android, iOS, WeChat applets and H5 web pages.
Tengxunyun VOD directly sent Buddha to the west, providing a set
Full Platform Super Player (TCPlayer)
. Not only is it perfectly compatible with all major platforms, but it also comes with functions such as definition switching, double-speed playback, barrage, thumbnail preview, skin customization, etc. Developers only need to copy a few lines of code, and a high-end player is successfully embedded.
Actual combat in the 4. industry: which scenes close your eyes and choose VOD?

Video and audio full hosting (no need to build a server) by the amount of billing (save money)
5. Summary: Leave professional matters to professional teams
Many technical leaders often fall into a misunderstanding that they have to write and build everything by themselves before they have core technology. But in fact, in the field of streaming media, which is extremely intricate and has high technical barriers, the cost performance of repeated wheel building is extremely low.
The essence of Tengxun Cloud VOD is that it packs the huge bandwidth bonus and audio and video black technology that Tencent has accumulated from its past operations of Tencent Video and WeChat WeChat Channels into one
Minimalist cloud components
.
You don't need to know what FFmpeg parameters are, you don't need to know how to configure HLS slices, and you don't need to have a huge audio and video operation and maintenance team. When you open VOD, you're hiring a whole team of top streaming experts. Venting your energy and focusing on optimizing your business logic and user experience is the most efficient way to play in the digital age.
