I want to extract audio from video with this method:

I’m developing a Flutter app for a caption embeding on a video that needs to export a video file after processing it. I’m using the flutter_ffmpeg_kit package. However, I’m having trouble getting the export to work correctly.

I have an image picker in flutter ro get the video from the device. and then i created a function to extract the audio using ffmpeg_kit_flutter package.

I’m trying to convert video to audio using flutter ffmpeg kit package but it is returning ReturnCode 1 which is false

I was using video_player to do the rest of the metadata extraction I need but I didn’t find a way to get the resolution with this package.
