Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

Try to concatenate videos using FFmpeg Package. My videos concatenate correctly but those that i record from fornt camera rotate 90' in concatenate
24 avril 2024, par Ahmad AkramHere is my code where I pass a list of image paths that concatenate. I am facing an issue with the front camera video. When concatenated completely some videos rotate 90 degrees.


Future<void> mergeVideos(List<string> videoPaths) async {
 VideoHelper.showInSnackBar('Videos merged Start', context);
 String outputPath = await VideoHelper.generateOutputPath();
 FlutterFFmpeg flutterFFmpeg = FlutterFFmpeg();

 // Create a text file containing the paths of the videos to concatenate
 String fileListPath =
 '${(await getTemporaryDirectory()).path}/fileList.txt';
 File fileList = File(fileListPath);
 await fileList
 .writeAsString(videoPaths.map((path) => 'file \'$path\'').join('\n'));

 // Run FFmpeg command to concatenate videos
 // String command = '-f concat -safe 0 -i $fileListPath -c copy $outputPath';

 String command =
 '-f concat -safe 0 -i $fileListPath -vf "transpose=1" -c:a copy $outputPath';

 VideoHelper.showInSnackBar('command Start', context);
 await flutterFFmpeg.execute(command).then((value) {
 if (value == 0) {
 print("Output Path : $outputPath");
 VideoHelper.showInSnackBar('Videos merged successfully', context);
 Navigator.push(
 context,
 MaterialPageRoute(
 builder: (context) => VideoPlayerScreen(
 videoFile: XFile(outputPath),
 )));
 } else {
 VideoHelper.showInSnackBar(
 'Error merging videos ::::: returnCode=== $value ', context);
 }
 });
 }
</string></void>

Is there a way to horizontal flip video captured from flutter front camera
5 mai 2024, par JoyJoyBasically, I'm trying to flip video horizontally after capturing it from flutter front camera. So I start recording, stop recording, flip the video and pass it to another page. I'm fairly new and would appreciate any assistance as my code isn't working


I've tried doing so using the new ffmpeg_kit flutter


Future<void> flipVideo(String inputPath, String outputPath) async{
final ffmpegCommand = "-i $inputPath -vf hflip $outputPath";
final session = FFmpegKit.executeAsync(ffmpegCommand);
await session.then((session) async {
 final returnCode = await session.getReturnCode();
 if (ReturnCode.isSuccess(returnCode)) {
 print('Video flipping successful');
 } else {
 print('Video flipping failed: ${session.getAllLogs()}');
 }
});}

void stopVideoRecording() async {
XFile videopath = await cameraController.stopVideoRecording();

try {
 final Directory appDocDir = await 
 getApplicationDocumentsDirectory();
 final String outputDirectory = appDocDir.path;
 final String timeStamp = DateTime.now().millisecondsSinceEpoch.toString();
 final String outputPath = '$outputDirectory/flipped_video_$timeStamp.mp4';

 await flipVideo(videopath.path, outputPath);

 // Once completed,
 Navigator.push(
 context,
 MaterialPageRoute(
 builder: (builder) => VideoViewPage(
 path: File(outputPath),
 fromFrontCamera: iscamerafront,
 flash: flash,
 )));
 print('Video flipping completed');
} catch (e) {
 print('Error flipping video: $e');
}
</void>

}

FFmpeg to RTMP - no audio on output [closed]
25 mars 2022, par John Mergene ArellanoFrom my client side, I am sending a stream using the Socket.IO library. I captured the video and audio using getUserMedia API.


navigator.mediaDevices.getUserMedia(constraints).then((stream) => {
 window.videoStream = video.srcObject = stream;
 let mediaRecorder = new MediaRecorder(stream, {
 videoBitsPerSecond : 3 * 1024 * 1024
 });
 mediaRecorder.addEventListener('dataavailable', (e) => {
 let data = e.data;
 socket.emit('live', data);
 });
 mediaRecorder.start(1000);
});


Then my server will receive the stream and write it to FFmpeg.


client.on('live', (stream)=>{
 if(ffmpeg)
 ffmpeg.stdin.write(stream);
});


I tried watching the live video in VLC media player. There is a 5 seconds delay and no audio output.


Please see below for FFmpeg options I used :


ffmpeg = this.CHILD_PROCESS.spawn("ffmpeg", [
 '-f',
 'lavfi',
 '-i', 'anullsrc',
 '-i','-',
 '-c:v', 'libx264', '-preset', 'veryfast', '-tune', 'zerolatency',
 '-c:a', 'aac', '-ar', '44100', '-b:a', '64k',
 '-y', //force to overwrite
 '-use_wallclock_as_timestamps', '1', // used for audio sync
 '-async', '1', // used for audio sync
 '-bufsize', '1000',
 '-f',
 'flv',
 `rtmp://127.0.0.1:1935/live/stream` ]);


What is wrong with my setup ?


I tried removing some of the options but failed. I am expecting to have an output of video and audio from the getUserMedia API.
