Supported codecs.
Actually, the following codecs are supported by flutter_sound:
iOS encoder
iOS decoder
Android encoder
This table will eventually be upgraded when more codecs will be added.
✅ (*) : The codec is supported by Flutter Sound, but with a File Format Conversion. This has several drawbacks :
Needs FFmpeg. FFmpeg is not included in the LITE flavor of Flutter Sound
Can add some delay before Playing Back the file, or after stopping the recording. This delay can be substancial for very large records.
Webkit is bull shit : you cannot record anything with Safari, or even Firefox/Chrome on iOS.
Opus WEBM is a great Codec. It works on everything (mobile and Web Browsers), except Apple
Edge is same as Chrome
