How to extract audio from video with ffmpegKit in flutter
8 juillet 2024, par Carlos PeñarandaI want to extract audio from video with this method :


Future<audio> extractAudio(Video video, String formatAudioByUser) async {
 
 final pathAudio = video.pathIn;

 FFmpegKit.execute(
 '-i ${video.pathIn} -q:a 0 -map a audio_${video.title}.mp3')
 .then((session) async {
 final returnCode = await session.getReturnCode();

 if (ReturnCode.isSuccess(returnCode)) {
 Fluttertoast.showToast(msg: 'Extraccion exitosa');
 } else if (ReturnCode.isCancel(returnCode)) {
 Fluttertoast.showToast(msg: 'Extraccion cancelada');
 } else {
 final error = await session.getFailStackTrace();
 Fluttertoast.showToast(msg: 'Fallo al extraer audio: $error');
 }
 });

//creates object
 final audio = Audio(
 id: 'audio_${video.id}',
 title: 'audio_${video.title}',
 duration: video.duration,
 pathIn: video.pathIn, 
 pathOut:pathAudio,
 format: formatAudioByUser,
 );
 
 return audio;
 }
</audio>

which i use in my datasource_impl.


But when choosing the media (video) and running the method, it doesn't work from the ffmpegkit script, and it shows this error :
"Fallo al extraer audio: null"

I've reviewed the debugging mode, and created brakpoints, but all the video data looks good.

How to execute this CMD Script in a Batch File ?
10 août 2024, par Edgar Ferreira

I am trying to make a batch file that when executes makes a list named VideosToJoin.txt of the files with the extension .mp4, .mts and .avi in the folder and the after that proceed with the concat of those same files creating a final one named FinalVideo.mp4
I need some help here, because i want to automatize a specific process...


(for %i in (*.mp4,*.mts,*.avi) do @echo file '%i') > VideosToJoin.txt 
 
ffmpeg -f concat -i VideosToJoin.txt -c copy FinalVideo.mp4


The expected result is to have the final video by executing just one file, that's all i want, please help.
