can we use -vf and -filter:a with -filter_complex
15 avril 2021, par Eswar TI want to combine some videos with some specific features like(video Speed, volume increase, resolution, rotation, framerate) of the final output of the video
We can do this process in 2 steps like


Combine video


ffmpeg -i test1.mp4 -i test2.mp4 -filter_complex [0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa] -map [outv] -map [outa] output.mp4


Then apply filters


ffmpeg -i output.mp4 -filter:a volume=1.0,atempo=1.0 -vf transpose=2,setpts=1/1.0*PTS,scale=3840X2160,fps=30 final.mp4


I can do it this way but is there any way to do it in 1 step


thank you

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 ?

moviepy ruining video after combining them
1er juin 2020, par jjakeryanI'm trying to make a program that downloads videos from TikTok and combines all the separate videos into one .mp4 file and moves the final video to a folder on my desktop. I've been able to make it download all the videos and when I watch the separate videos they play fine however when I combine the videos some of the videos are messed up and look like this but the audio is fine.



#slecting all .mp4 files
 video_files = glob.iglob("*.mp4")

 print(video_files)
 clips = []

 for clip in video_files: # For each mp4 file name
 clips.append(VideoFileClip(clip)) # Store them as a VideoFileClip and add to the clips list

 today = date.today()

 final = concatenate_videoclips(clips) # Concatenate the VideoFileClips
 final.write_videofile(f"{today}.mp4", codec="libx264")


#moving completed video to folder on desktop
 shutil.move(f'{today}.mp4', '/Users/jacobmarrandio/Desktop/done_videos/')



thanks for any help
