How to export a video with a widget overlay in a Flutter app ?
30 juin 2024, par Mohammed BekeleI'm developing a Flutter app for a caption embeding on a video that needs to export a video file after processing it. I'm using the flutter_ffmpeg_kit package. However, I'm having trouble getting the export to work correctly.


Here's the code I'm using :


initially this is my stack


Expanded(
 child: Stack(
 children: [
 Center(
 child: _videoPlayerController.value.isInitialized
 ? AspectRatio(
 aspectRatio:
 _videoPlayerController.value.aspectRatio,
 child: VideoPlayer(_videoPlayerController),
 )
 : CircularProgressIndicator(),
 ),
 if (_currentCaption.isNotEmpty)
 Positioned.fill(
 child: Center(child: _buildCaptionText()),
 ),
 ],
 ),
 ),


and in export button i executed this function


Future<void> _exportVideo() async {
 setState(() {
 _isProcessing = true;
 });

 try {
 final directory = await getExternalStorageDirectory();
 final rootPath = directory?.parent.parent.parent.parent.path;
 final mobixPath = path.join(rootPath!, 'Mobix App');
 final appPath = path.join(mobixPath, 'Caption');
 final outputPath = path.join(appPath, 'Output');

 // Create the directories if they don't exist
 await Directory(outputPath).create(recursive: true);

 final timestamp = DateTime.now().millisecondsSinceEpoch;
 final outputFilePath = path.join(outputPath, 'output-$timestamp.mp4');


 // Generate the FFmpeg command
 final ffmpegCommand = _generateFFmpegCommand(
 widget.videoPath,
 outputFilePath,
 widget.words,
 _fontSize,
 _isBold,
 _isItalic,
 _fontColor,
 _backgroundColor,
 );

 // Execute the FFmpeg command
 await FFmpegKit.execute(
 ffmpegCommand,
 ).then(
 (session) async {
 // Update progress if needed
 final returnCode = await session.getReturnCode();
 if (ReturnCode.isSuccess(returnCode)) {
 setState(() {
 _outputFilePath = outputFilePath;
 });
 ScaffoldMessenger.of(context).showSnackBar(
 SnackBar(content: Text('Export successful: $_outputFilePath')),
 );
 } else {
 print('Export failed with rc: $returnCode');

 ScaffoldMessenger.of(context).showSnackBar(
 SnackBar(content: Text('Export failed with rc: $returnCode')),
 );
 }
 setState(() {
 _isProcessing = false;
 });
 },
 );
 } catch (e) {
 print('Export failed: $e');
 ScaffoldMessenger.of(context).showSnackBar(
 SnackBar(content: Text('Export failed: $e')),
 );
 setState(() {
 _isProcessing = false;
 });
 }
 }

 String _generateFFmpegCommand(
 String inputPath,
 String outputPath,
 List<dynamic> words,
 double fontSize,
 bool isBold,
 bool isItalic,
 Color fontColor,
 Color backgroundColor,
 ) {
 final ffmpegCommand = StringBuffer();

 // Add input file
 ffmpegCommand.write('-i $inputPath ');

 // Add subtitles filter
 final subtitleFilter = StringBuffer();
 for (var word in words) {
 final startTime = word['startTime'].toDouble();
 final endTime = word['endTime'].toDouble();
 final caption = word['word'];

 final fontStyle = isBold && isItalic
 ? 'bold italic'
 : isBold
 ? 'bold'
 : isItalic
 ? 'italic'
 : 'normal';
 final fontColorHex = fontColor.value.toRadixString(16).substring(2);
 final backgroundColorHex =
 backgroundColor.value.toRadixString(16).substring(2);

 subtitleFilter.write(
 "drawtext=text='$caption':x=(w-tw)/2:y=h-(2*lh):fontcolor=$fontColorHex:fontsize=$fontSize:fontStyle=$fontStyle:box=1:boxcolor=$backgroundColorHex@0.5:boxborderw=5:enable='between(t,$startTime,$endTime)',");
 }
 ffmpegCommand.write('-vf "${subtitleFilter.toString()}" ');

 // Add output file
 ffmpegCommand.write('$outputPath');

 return ffmpegCommand.toString();
 }
</dynamic></void>

when i run this it returns ReturnCode 1. what am i doing wrong ?
