Nice development @kisvegabor! Unfortunately I'm still on v8.3 so testing your PR will involve quite a bit of refactoring for me. I'll report back when I get it done.

The next frame callback is initialized using the frame rate specified in the lottie:

lvgl/src/extra/libs/rlottie/lv_rlottie.c

Line 148 in 36a8052

 rlottie->task = lv_timer_create(next_frame_task_cb, 1000 / rlottie->framerate, obj); 

and then in the callback, the frame number is simply incremented by 1:

lvgl/src/extra/libs/rlottie/lv_rlottie.c

Lines 253 to 254 in 36a8052

 if(rlottie->current_frame < rlottie->total_frames) 

 ++rlottie->current_frame;

I think it should instead calculate which frame should be rendered based on the time elapsed.

Hi,

Can you try it this PR? It uses a more recent Lottie implementation and it's also easier to integrate into LVGL.
