ffmpeg_kit_flutter operation not permitted for audio operations
25 août 2023, par Black Eyed BeansI'm trying to trim an audio file using
ffmpeg_kit_flutterbut I keep getting the error :

audio/path/output.mp3: Operation not permitted.


This is the ffmpeg command that I'm using :


final cmd="-y -i \"$audioPath\" -ss $audioStartTime -to $audioEndTime -c:a libmp3lame $outPutName";


And I've also tried :


final cmd="-y -i \"$audioPath\" -ss $audioStartTime -to $audioEndTime -c copy $outPutName";


But the error is still the same.
I'm using the
ffmpeg_kit_flutter_full_gplpackage.

Combining multiple image files into a video while using filter_complex to apply a watermark
14 décembre 2017, par GeuisI’m trying to combine two ffmpeg operations into a single one.
Currently I have two sets of ffmpeg commands that first generate a video from existing images, then runs that video through ffmpeg again to apply a watermark.
I’d like to see if its possible to combine these into a single operation.
# Create the source video
ffmpeg -y \
-framerate 1/1 \
-i layer-%d.png \
-r 30 -vcodec libx264 -preset ultrafast -crf 23 -pix_fmt yuv420p \
output.mp4
# Apply the watermark and render the final output
ffmpeg -y \
-i output.mp4 \
-i logo.png \
-filter_complex "[1:v][0:v]scale2ref=40:40[a][b];[b][a]overlay=(80):(main_h-200-80)" \

How to extract audio from a video in Flutter ?
14 janvier, par Mohammed BekeleI have an image picker in Flutter to get the video from the device, and then I created a function to extract the audio using ffmpeg_kit_flutter package.


Future<void> _convertVideoToAudio() async {
 if (_pickedVideo != null) {
 bool? permissionGranted = await _requestStoragePermission();
 if (permissionGranted != true) {
 print("Storage permission denied.");
 return;
 }

 String videoPath = _pickedVideo!.path;
 _outputPath = await getOutputFilePath(); // Get platform-specific path

 try {
 // Ensure the output directory exists
 await Directory(path.dirname(_outputPath)).create(recursive: true);

 await FFmpegKit.execute(
 "-i $videoPath -vn -c:a libmp3lame -q:a 2 $_outputPath"); // FFmpeg command
 print("Video converted to audio successfully!");
 _showSuccessDialog(); // Display success dialog

 try {
 final String fileName = path.basename(_outputPath);
 final transcription =
 await _sendAudioForTranscription(_outputPath, fileName);

 if (transcription != null) {
 setState(() {
 _transcription = transcription;
 });
 } else {
 setState(() {
 _transcription = "Transcription failed";
 });
 }
 } catch (e) {
 print('Error in transcription request: $e');
 setState(() {
 _transcription = "Network request failed";
 });
 }
 } catch (e) {
 print("Error converting video: $e");
 _showErrorDialog(); // Display error dialog
 } finally {
 setState(() {
 _pickedVideo = null; // Clear selected video
 });
 }
 } else {
 print("Please pick a video first.");
 }
 }
</void>

and for getting the path I have this function


Future<string> getOutputFilePath() async {
 final directory = await getApplicationDocumentsDirectory();
 final downloadsDirectory = Directory('${directory.path}/downloads');
 if (!(await downloadsDirectory.exists())) {
 await downloadsDirectory.create(recursive: true);
 }
 final String fileName = path
 .basename(_pickedVideo!.path)
 .replaceAll('.mp4', '.mp3'); // Replace extension
 final filePath = '${downloadsDirectory.path}/$fileName';
 return filePath;
 }
</string>

but this is not working somehow. Because after I get the audio I'm uploading it to a server with http, then it displays that there is no path where the audio supposed to be.
