How to add a subtitle to a video using ffmpeg in Flutter ?
3 juillet 2024, par Mohammed BekeleI'm using flutter_ffmpeg_kit_full package to add subtitles to my video. First I loop through all words and create an srt file and stored it in temp folder :


Future<string> _createSrtFile() async {
 String filePath = await getSrtOutputFilePath();

 final file = File(filePath);
 final buffer = StringBuffer();

 for (int i = 0; i < widget.words.length; i++) {
 final word = widget.words[i];
 final startTime = _formatSrtTime(word['startTime'].toDouble());
 final endTime = _formatSrtTime(word['endTime'].toDouble());
 final text = word['word'];

 buffer.writeln('${i + 1}');
 buffer.writeln('$startTime --> $endTime');
 buffer.writeln('$text');
 buffer.writeln('');
 }

 await file.writeAsString(buffer.toString());
 return filePath;
 }

 String _formatSrtTime(double seconds) {
 final int hours = seconds ~/ 3600;
 final int minutes = ((seconds % 3600) ~/ 60);
 final int secs = (seconds % 60).toInt();
 final int millis = ((seconds - secs) * 1000).toInt() % 1000;

 return '${hours.toString().padLeft(2, '0')}:${minutes.toString().padLeft(2, '0')}:${secs.toString().padLeft(2, '0')},${millis.toString().padLeft(3, '0')}';
 }
</string>

Then I create a future function to handle the export by using ffmpeg command :


Future<void> _exportVideo() async {
 final hasPermission = await _requestStoragePermission();
 if (!hasPermission) {
 ScaffoldMessenger.of(context).showSnackBar(
 const SnackBar(content: Text('Storage permission denied')));
 return;
 }

 setState(() {
 _isProcessing = true;
 _outputFilePath = "";
 });

 try {
 final srtFilePath = await _createSrtFile();

 String videoPath = widget.videoFile!.path;

 String _outputPath = await getOutputFilePath();

 final command =
 '-i $videoPath -vf "drawtext="text=\'Stack Overflow\':fontcolor=white:fontsize=24:box=1:boxcolor=black@0.5:boxborderw=5:x=(w-text_w)/2:y=(h-text_h)/2"" -codec:a copy $_outputPath';

 // final cmd = [
 // '-i',
 // videoPath,
 // '-preset',
 // 'ultrafast',
 // '-vf',
 // 'subtitles=$srtFilePath:force_style=\'Fontname=Roboto Bold,FontSize=30,MarginV=70,PrimaryColour=ffffff,OutlineColour=000000\'',
 // _outputPath
 // ];
 // FFmpegKit.executeWithArguments(cmd)

 print('Executing FFmpeg command: $command');

 await FFmpegKit.execute(command).then((session) async {
 final returnCode = await session.getReturnCode();
 final output = await session.getOutput();
 final failStackTrace = await session.getFailStackTrace();

 print('FFmpeg Output: $output');
 if (failStackTrace != null) {
 print('FFmpeg Fail StackTrace: $failStackTrace');
 }

 if (ReturnCode.isSuccess(returnCode)) {
 setState(() {
 _outputFilePath = _outputPath;
 });
 ScaffoldMessenger.of(context).showSnackBar(
 const SnackBar(content: Text('Export successful!')));
 } else {
 final logs = await session.getLogsAsString();
 print('FFmpeg Logs: $logs');
 ScaffoldMessenger.of(context)
 .showSnackBar(const SnackBar(content: Text('Export failed!')));
 }
 });
 } catch (e) {
 print('Error: $e');
 ScaffoldMessenger.of(context).showSnackBar(
 SnackBar(content: Text('Export failed with error: $e')));
 } finally {
 setState(() {
 _isProcessing = false;
 });
 }
 }
</void>

I did the export without the subtitles and it works. but the issue is when I try to do it with subtitles. I don't know what fault I'm making but this code is failing to export. Here is the path for the srt and video itself :


Future<string> getOutputFilePath() async {
 final Directory? downloadsDir = await getDownloadsDirectory();
 final timestamp = DateTime.now().millisecondsSinceEpoch;
 final name = "output-$timestamp.avi";
 return '${downloadsDir!.path}/$name'; // Save in downloads folder
 }

 Future<string> getSrtOutputFilePath() async {
 final Directory? downloadsDir = await getDownloadsDirectory();
 final timestamp = DateTime.now().millisecondsSinceEpoch;
 final name = "caption-$timestamp.srt";
 return '${downloadsDir!.path}/$name'; // Save in downloads folder
 }
</string></string>

Batch script cannot read file if there is a space
25 août 2022, par ShahpariCD "C:\Input"
for %%a in ("*.*") do "C:\ffmpeg.exe" -i %%a -map 0:v -map 0:a:0 -map 0:s -c:v copy -c:a ac3 -b:a 640K "C:\Out\%%~na.mkv"
pause


if there is no space this script works fine, but if there is a space in file name, the script reads only the first word of the file and throws an error. i tried to add a double quote first %%a. but then the script does not even run.


here is an example file name :

[TEST] ABC test - 99
