java.lang.IllegalArgumentException: Unsupported value: 'kotlin.Unit' of type 'class kotlin.Unit'

[cnkygmr]

MediaInfo? mediaInfo = await VideoCompress.compressVideo(file.path, quality: VideoQuality.MediumQuality, includeAudio: true);

I use it this way, it works normally, but when I leave the page I am processing, it gives the following error? I want it to continue doing it in the background but it throws an error

[lakshmansha]

I am also facing the same issue.

[gOzaru]

I think the problem is in video format. It should be mp4 only. And it cannot be using Adobe Media Encoder to compile it. Sometime the format is read as mp4v and that is not compatible and caused such error.

[karamatpkid]

Not due to Mp4, because in my folder all videos are in MP4.
