ffmpeg complex filter - multiple crops on black background
31 octobre 2017, par Kevin O'HaraWe are attempting to process a video file by cropping it into several pieces and arranging it on a black background which is exactly 1920x1080. The following command runs but it never completes and we have to kill the process.
Is there something wrong with how we’re trying to do this ?
ffmpeg -i in.mov -y -filter_complex "\
color=s=1920x1080:c=black[bg];\
[0:v]crop=w=1920:h=ih:x=0:y=0[crop1];\
[0:v]crop=w=iw-1920:h=ih:x=1920:y=0[crop2];\
[bg][crop1]overlay=x=0:y=0[out1];\
[out1][crop2]overlay=x=0:y=h[final]" \
-map [final] out.mov -
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.

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)" \
final.mp4
