there is some unique concept about processing Lottie Animations using FFMPEG video processing library and MediaCodec. In that, I wants to make video from Lottie animation and overlay that video on other original video.
But the problem is i'm unable to make a video with transparent background from Lottie animation. So i made simple video from Lottie animation using MediaCodec and MediaMuxer, it takes one by one frame from Lottie Drawable and attach it to the video(Lottie Video). Here is the link about this concept- https://engineering.21buttons.com/how-to-generate-videos-using-lottie-in-android-2db6ecceb2a
And then i overlay this video to the original video using FFmpeg library. Here FFmpeg does two task, first it makes transparent background in Lottie Video and second it overlays this Lottie Video above the original video.
And here the actual problem is out, FFmpeg takes more than 8 to 9 minutes in processing of video of 25 seconds, So i wants to get solution for this problem, as i have time limit of only 1 to 2 minutes. Any one has a solution for it or new ides for implementation of this concept, then please tell me i'll appreciate it.
