Simple 4 Steps: Quickly Embed Beauty SDK Effects in Real-time Video Calls
Updated：2025-09-04
Background: The "Urgent Need" for Real-Time Beauty FeaturesRemote work has become increasingly frequent lately, and I have to attend video meetings with my team several times a week. As a programmer who often stays up late to meet project deadlines, I always look sallow on camera with panda-like dark circles. Every time a colleague screenshots me and sends it to the group chat, I just want to find a hole to crawl into.
Last month, our product manager suddenly said we needed to add real-time beauty features to our app (allowing users to adjust skin smoothing and face slimming during video calls). I was instantly overwhelmed — how could our small team handle such underlying technology?
I spent three days digging through open-source projects on GitHub, but either the effects looked as fake as plastic dolls, or the latency was so high that the mouth movements didn’t match the speech. Later, a friend recommended Lanji Beauty SDK. I decided to give it a try as a last-ditch effort, and surprisingly, it actually worked. Looking back now, the whole process only took four steps, which was much simpler than I imagined.
The 4-Step Implementation Process
Step 1: Register a Developer Account & Download SDK
After signing up on Lanji’s official website, I could download the SDK package directly. What impressed me most was that it included detailed integration documentation — even someone like me who has a fear of reading docs could understand it easily.
After unzipping, I found the core files were only about 5MB, much cleaner than those SDKs I downloaded before that were often hundreds of megabytes.
Step 2: Configure the Development Environment
I imported the SDK into the project according to the documentation. A key note here: permission applications (especially camera and microphone permissions) are a must!
I made a silly mistake at first — forgetting to add the camera permission in AndroidManifest.xml. As a result, the camera wouldn’t turn on during debugging. I struggled for half an hour before figuring it out, and I almost smashed my computer out of frustration.
Step 3: Write the Calling Code
The best part about Lanji’s SDK is its pre-packaged APIs — you can enable basic beauty effects with just three lines of code!
I tested the skin smoothing parameter: as I slid the value from 0 to 100, the acne marks in the video really blurred gradually. The real-time feedback felt amazing. But be careful: setting the face-slimming parameter too high will make the face look like a cone — my colleagues laughed for ages when they saw the test version.
Step 4: Test & Optimize
I tested the feature on all the company’s test phones, from budget 1000-yuan models to the latest flagships — no crashes at all!
The biggest surprise was the low latency: even on older iPhones, the delay was controlled within 80 milliseconds, which didn’t affect normal calls at all. Now I secretly turn on light beauty effects during every video meeting — my colleagues all say I look better lately, but only I know my secret weapon.
Conclusion: Choosing the Right Tool Saves Time & Effort
To be honest, I used to think beauty SDKs were really complicated, and that you’d definitely need to spend a lot of money hiring a professional team to develop them. But after doing it myself this time, I realized that choosing the right tool can save you a lot of trouble.
Now our app’s beauty feature has been online for two weeks, and finally, no users are complaining that "the video looks like a monster mirror" in the feedback. My boss even said he’d give me a raise!
