setOutputFormat method
Sets the format of the output file produced during recording. Call this after setAudioSource/setVideoSource but before prepare.
It is recommended to always use 3GP format when using the H.263 video encoder and AMR audio encoder. Using an MPEG-4 container format may confuse some desktop players.
Implementation
Future<void> setOutputFormat(int format) =>
_channel.$setOutputFormat(this, format);
