Saving malformed AAC on Android

[z411]

Package version
6.0.0

Environment

• Android 13 (MIUI 12)

Describe the bug

AAC on Android is getting saved correctly although with malformed data. It will play on most players but they will have trouble with the first frames, thus outputting an error before playing. Due to this, browsers like Firefox and Chrome will refuse to play them at all.

ffmpeg outputs this:

[ffmpeg/audio] aac: Input buffer exhausted before END element found
Error decoding audio.

To Reproduce

Steps to reproduce the behavior:

1. Use RecordConfig(encoder: AudioEncoder.aacLc)
2. Record

Expected behavior

AAC file without errors that can be played anywhere.

Additional context

This works fine on the Linux build. I noticed this because Opus wasn't working on my device (#508) and it would be better to fix that instead.
