Unable to split audio using easy_audio_trimmer
27 juillet 2023, par Sana Wasimcan we use the easy_audio_trimmer package to split an audio ? I tried using the ffmpeg but it is conflicting with the above package and not work.


I tried splitting by using these functions and it gave an error at the FlutterFFmpeg() method and i cant find an alternative also the duration(filePath) in the command final durationResult = await flutterSound.duration(filePath) ; shows an error


Future<void> _splitAudio() async {
 setState(() {
 _progressVisibility = true;
 });

 // Get the application documents directory
 final appDocumentsDirectory = await getApplicationDocumentsDirectory();

 // Get the input audio file path
 final inputAudioPath = widget.file.path;

 // Get the output file names for the two parts
 final outputFileName1 = 'split_audio_part1.mp3';
 final outputFileName2 = 'split_audio_part2.mp3';

 // Get the output file paths for the two parts
 final outputPath1 = '${appDocumentsDirectory.path}/$outputFileName1';
 final outputPath2 = '${appDocumentsDirectory.path}/$outputFileName2';

 // Calculate the duration of the original audio
 final originalDuration = await _getAudioDuration(inputAudioPath);

 // Calculate the durations of the two parts
 final part1Duration = _startValue;
 final part2Duration = originalDuration - _endValue;

 // Construct the FFmpeg command to split the audio
 final ffmpeg = FlutterFFmpeg();
 final splitCommand = '-i $inputAudioPath -ss 0 -t $part1Duration -c copy $outputPath1 -ss $_endValue -t $part2Duration -c copy $outputPath2';

 try {
 // Execute the FFmpeg command to split the audio
 final int result = await ffmpeg.execute(splitCommand);

 if (result == 0) {
 setState(() {
 _progressVisibility = false;
 });
 debugPrint('Audio split successfully.');
 } else {
 setState(() {
 _progressVisibility = false;
 });
 debugPrint('Failed to split audio.');
 }
 } catch (error) {
 setState(() {
 _progressVisibility = false;
 });
 debugPrint('Error while splitting audio: $error');
 }
 }

 Future<int> _getAudioDuration(String filePath) async {
 final flutterSound = FlutterSound();
 final durationResult = await flutterSound.duration(filePath);
 return durationResult.inMilliseconds;
 }
</int></void>

FFMPEG : Converting from raw audio to audio/mp4 (audio is being converted with slow speed)
29 décembre 2017, par ValdirIf I convert from mp3 to mp4 directly everything works perfectly. But if I try to convert from raw pcm, the audio speed is slowed down.
I’ve tried the following (this works) :
ffmpeg -i mp3/1.mp3 -strict -2 final.mp4This doesn’t work as expected :
ffmpeg -f s16le -i final.raw -strict -2 -r 26 final.mp4With the following output :
Input #0, s16le, from 'final.raw':
Duration: 00:08:37.38, bitrate: 705 kb/s
Stream #0:0: Audio: pcm_s16le, 44100 Hz, 1 channels, s16, 705 kb/s
File 'final.mp4' already exists. Overwrite ? [y/N] y
Output #0, mp4, to 'final.mp4':

ffmpeg -ar 44100 -f s16le -i final.raw -strict -2 -r 26 final.mp4With no luck.
In order to get the PCM from mp3 I’m using nodejs lame decoder :
var decoder = new lame.Decoder({
channels: 2,
bitDepth: 16,
sampleRate: 44100,
bitRate: 128,
outSampleRate: 44100, // 22050
