In FFmpeg You can do it by playing the audio, recording video and then merging two files like
final FlutterFFmpeg _ffMpeg = FlutterFFmpeg();
_ffMpeg.execute("-i video.mp4 -i audio.mp4 -c copy output.mp4")
.then((return_code) => print("Return code $return_code"));
With FFmpeg You need to find the command that suits You the best.
But... Personally I think FFmpeg isn't a good choice:
- It is heavy
- You can't use it in commercial projects (I might be wrong, please correct me if I am)
What I suggest
You can record video and have audio file and video with Flutter. Then use platform specific code.
Even if you don't have experience in specific language I found those two libraries that could help:
iOS: https://github.com/dev-labs-bg/swift-video-generator (does exactly what You need).
Android: https://github.com/israel-fl/bitmap2video (I'm not sure if works with videos, but it accepts bitmaps)
