Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.

Flutter : Running FFmpeg.execute to generate thumbnails in a different isolate doesn't work ?
12 novembre 2024, par VasudevThis is the current code to generate thumbnails for Video and Audio files.. It is working fine in most cases.


@override
Future<imageprovider> thumbnail(String path,
{required double width, required double height}) async {


 final FFmpegSession session = await FFmpegKit.executeAsync(
 "-loglevel quiet -i '$filePath' -y -ss 00:00:00.000 -vframes 1 '$thumbnailPath'");


 final returnCode = await session.getReturnCode();
 if (returnCode == null || returnCode.isValueError()) {
 throw Exception("Thumbnail generation failed");
 }

/* Returns ImageProvider */
}
</imageprovider>

Now in iOS, for large files, the thumbnail generation doesn't really fail. But takes a long time and doesn't complete at all.


This causes performance issues. I would like to run this FFmpeg.execute() in a different isolate, but it doesn't work at all.


final FFmpegSession session = await Isolate.run(
 () async {
 return await FFmpegKit.executeAsync(
 "-loglevel quiet -i '$filePath' -y -ss 00:00:00.000 -vframes 1 '$thumbnailPath'");
 },
 );

ffmpeg timelapse discard garbage jpg [duplicate]
12 mai 2021, par pieknI'm successfully creating timelapse video (jpg->mp4) using command line
$ffmpeg -r $fps -f concat -safe 0 -i $concat_file -c:v libx264 -vf 'format=yuv420p' $thumbnail 2>&1 &


But some of source jpg are 'garbage' (look picture below what I mean) - part of the picture is lost.
part of picture is lost


As result, final clip contains damaged frames (see below)
final clip


As I see, the best for me is to discard these jpg. But I have no ideas how to define them ? - file system don't see them as 'broken', etc.


Any ideas ?

ffmpeg with Flutter - Error in my code - Video not created
30 juillet 2020, par csslerI try to create a video from images with flutter and
ffmpeg. I think the logic of my code is correct, but I always get the return value1which says that the execute was not successfull.

Do you find the error in my code ?


Future<void> _onCreateVideoFromImages() async {
 Directory tempDir = await getTemporaryDirectory();
 String tempPath = tempDir.path;

 final allPictures = await picturesData.getPicturesFromAlbum(albumID);

 List textFileMap = [];

 for (var i = 0; i < allPictures.length; i++) {
 var file = File(allPictures[i].path);

 final newFile = await file
 .copySync("$tempPath/img${i.toString().padLeft(4, '0')}.jpg");

 print("File has been moved successfully to temporary folder: $newFile");

 textFileMap.add("file '" + newFile.path + "'");
 }

 print("Final list:");
 print(textFileMap);

 print("Create txt file for ffmpeg");
 final File file = File('${tempPath}/images.txt');
 final textFile = await file.writeAsString(textFileMap.join("\n"));
 print("txt file created successfully: $textFile");

 await _flutterFFmpeg.execute(
 "ffmpeg -f concat -safe 0 -i $textFile -c copy $tempPath/output.mp4")
 .then((rc) {
 if (rc == 0) {
 print("Video completed");
 } else {
 print(rc); // Returns 1
 }
 });
 }
</void>

And here the console log


flutter: File has been moved successfully to temporary folder: File: '/var/mobile/Containers/Data/Application/C28A04D5-76DF-450B-8F63-75CD39BC927F/Library/Caches/img0001.jpg'
