Use webcodec to accelerate lottie to video
Dramalf opened this issue · comments
Use puppeteer in nodejs using webcodec to convert lottie file to mp4 video
No need to take screenshot of each frame (it takes much time）
Its workflow basiclly looks like this:
- load in puppeteer lottie-web
- encode each frame by webcodec API : VideoEncoder and VideoFrame
- frames -> buffer -> blob -> file
- send back to nodejs
- use ffmpeg to generate video
I write a demo here https://github.com/Dramalf/puppeteer-webcodec-lottie/tree/master
I think it can be merged into this project
