Logs!!!

i put some try catch on my code to see the output, this is the log on debug

I/flutter (14966): ---------------------------------------- I/flutter (14966): convert start I/flutter (14966): ---------------------------------------- D/flutter-ffmpeg(14966): Running FFmpeg with arguments: [-loglevel, error, -y, -i, /data/user/0/com.example.topos/cache/300621-19#58-Bornage-Immatriculation.aac, /storage/emulated/0/Topos/300621-19#58-Bornage-Immatriculation.mp3].

D/flutter-ffmpeg(14966): FFmpeg exited with rc: 0 I/flutter (14966): ---------------------------------------- I/flutter (14966): convert end I/flutter (14966): ----------------------------------------

the aac file is the temp file, and the mp3 is the result of convert, the file is successfuly converted and it appear in the path where it would be. i don’t know if this line "D/flutter-ffmpeg(14966): Running FFmpeg with arguments: [-loglevel, error, -y, -i, " mean something important or not cause this error text.

But on release this convert make the app crash.

Below screenshot of my full code to save the record

Hi Necro,

Flutter Sound 8.1.9 is released. This version has a fix for your issue.

You must also check your build.gradle :

• Remove any reference to repository jcenter()
• Add a reference to mavenCentral() if not already done

I wrote a very simple example here that record an AAC audio, convert it to MP3 and playback it. You probably do not need any more this example : your code was correct and the problem was on Flutter FFmpeg.

Thank you for your patience

Might be better off using flutter sound lite and including ffmpeg as a separate dependency and running the commands directly.

Flutter_ffmpeg likes to crash or output weird things when multiple jobs are run concurrently. I had to create a queue system for ffmpeg calls to work around this. I’m sure there are other quirks and something like that could be causing this issue.

Best way forward is probably to run ffmpeg directly so you have full control over the process
