Tau: [BUG]: Build failed Android with FFMpeg

[Tom3652]

Flutter Sound Version :

flutter_sound: 8.2.0

• Important: Result of the command : flutter pub deps | grep flutter_sound

|-- flutter_sound 8.2.0
|   |-- flutter_sound_platform_interface 8.2.0
|   |-- flutter_sound_web 8.2.0
|   |   |-- flutter_sound_platform_interface...

---

Severity

• Cannot build my App

---

Platforms you faced the error

• Android
• Real device

---

Describe the bug
Build failed due to duplicate FFMPEG classes. There is a conflict between flutter_ffmpeg and flutter_sound
That makes flutter_sound unsable if we use flutter_ffmpeg in our project
I am making an issue here as ffmpeg doesn't seem to be depending on any other package and is "lower level" API that maybe flutter_sound is also using.

To Reproduce
Steps to reproduce the behavior:

1. Add the flutter_ffmpeg package to the latest version (0.4.0 at the time of this issue)
2. Add flutter_sound: ^8.2.0
3. Build the application on a real Android device

Use flutter_sound_lite which does not include ffmpeg

[Tom3652]

Thanks for your reply and suggestion, indeed it's now working !
However, where can i find the differences between the full and the lite version please ?

[mhstoller]

flutter_sound includes ffmpeg for some conversion methods between different codecs which you can use yourself, and this also allows it to support more codecs. See here: https://tau.canardoux.xyz/guides_codec.html

[Larpoux]

Actually, the only difference between the LITE flavor and the FULL flavor is only the inclusion of Mobile FFmpeg in the FULL version.
It is possible in the future that there will be some other differences, but actually this is only that.

The big reason of the FULL flavor, is to be able to play regular OPUS/OGG files on iOS.
Apple people are so stupids that their implementation of the OPUS codec use a proprietary File Format that is CAF instead of a normal OGG.
I really wanted Flutter Sound being able to play directely OPUS/OGG without having the App to do itself the conversion.

[Larpoux]

Also, one of my many projects will be to be able to record MP3 on the flight, without having to convert the file after recording.
To do that, I will use LAME, which is a free MP3 encoder and is part of FlutterFFmpeg.
