[Question] Slower by using dotLottie

[Drjacky]

I have a GIF that I converted to both JSON and Lottie file types. I used one by one but, when I use the Lottie filetype, it takes a couple of seconds to load the animation.

The Lottie version: 3.5.0

Hi!

When you say you've converted a GIF I assume you're either using the video->lottie tool or a manual process, but essentially have a sequence of image assets encapsulated in a Lottie yes?

IF that's the case you should be able to skip this loader lib and use lottie-android directly which might give you some speedups. The most likely issue is that images take a little bit of time and compute power to decompress

I see you used the video2lottie tool. You should be able to use that Lottie directly in lottie-android without this library and it should give you a performance boost.

I used Convert video and image sequence to Lottie (Beta) from https://app.lottiefiles.com/

Thank you for clarifying. Had a look and I believe the performance issues are coming from the double buffer from dotlottie-loader and lottie-android. I'd recommend the original suggestion of lottie-android directly. It should be able to support the file directly

I used Lottie-android and JSON and there is no issue.
