Multiple Overlay Filters Causing Memory Error - Flutter (Only for iOS)

Description I need to put overlay images to a video. It is working on Android without problem. But on iOS platform, if I try 23-24 overlay images, it is working correctly. If I try it with 30+ images, it gives memory allocation error.

Every overlay image is around 50 kb
Video is around 250 MB
I tried with smaller images, so I can use 40+ images without problem, so it is not related with counts, it is related with file size. I think there is a limit like 1MB for complex filter streams.

Most likely related with: #121 and #329

Expected behavior Exporting a video with different time based image overlays.

Current behavior Giving memory error.

To Reproduce You can try it with 30+ images which sizes per 50kb+ over Full HD video.
