Hi i'm using also ffmpeg_kit_flutter_full_gpl: ^4.5.1-LTS this cause duplicate classes failure. How can we change the package of ffmpeg plugins?

What went wrong:

Any update?

[dannycortesv]

@felipeemidio Make sure to use the same ffmpeg package on all puglins you use

[wolfwithflames]

Please help on this facing same issue.

[sbis04]

In your pubspec.yaml file, are you guys using both the ffmpeg_kit_flutter and the video_trimmer packages together?

[felipeemidio]

Yes, @sbis04. My case is that I want to use the video_trimmer package and the ffmpeg_kit_flutter_https_gpl for video convertion (both on version 4.5.1-LTS).

I'm not totally sure how this duplicate class error can be fixed, but this thread may help: https://stackoverflow.com/questions/56029393/why-im-getting-duplicate-class-when-running-my-android-project
