• How to enable third party login providers in .NET with sessionState set to SQL Server ?

  12 novembre 2015, par Rod

  My requirements are to create a webapp allowing third party logins (facebook specifically) and allow users to upload and share video.

  My development environment is :

  • Visual Studio Express 2013 for Web
  • SQL Server 2012
  • ASP.NET MVC project using C# deployed to Azure

  I’ve found invaluable information on Stack Overflow for using oAuth2 with third party login providers, and for enabling SQL Server session state, but what I would like to know is how can I use both of them together ?

  I originally started using SQL Server session state because the site loses session when a video is saved on the server, converted using NReco videoconverter, then saved to blob storage. However this broke my third party logins which need sessionState set to OFF.

  I tried accounting for this by converting the video STREAM with FFMpeg, and then saving directly to blob storage, but I still lose session.

  Any help would be appreciated on the topics of : Why am I losing session with NReco.VideoConverter ? How to use third party logins with sessionState set to SQL Server ?

• Transform video and image with multer-s3-transform

  6 mai 2022, par Nguyen Hoang Vu

  I'm trying to upload media to S3 with multer-s3-transform
Here is my endpoint :

  


  router.post(
    ROUTE_CONSTANT.PRODUCT_IMAGES,
    validation.verifyProductExisted,
    uploadImage.single('image'),
    uploadProductImage
  );


  


  Here is my multer-s3-transform implementation :

  


    const uploadImage = multer({
  fileFilter: imageTypeFilter,
  limits: {
    fileSize: configEnv.mediaFileSizeLimit * 1024 * 1024,
  },
  storage: multerS3({
    s3,
    bucket: configEnv.productMediaBucket,
    acl: 'public-read',
    contentType: multerS3.AUTO_CONTENT_TYPE,
    shouldTransform(
      req: Request,
      file: Express.Multer.File,
      cb: (arg0: any, arg1: boolean) => void
    ) {
      cb(null, true);
    },
    transforms: [
      {
        id: 'original',
        key(
          req: Request,
          file: Express.Multer.File,
          cb: (arg0: any, arg1: string) => void
        ) {
          const fileName = `${req.params.id}-${new Date().getTime()}`;
          if (imageMimeType.includes(file.mimetype)) {
            cb(null, `images/${fileName}.jpg`);
          } else {
            cb(null, `videos/${fileName}.mp4`);
          }
        },
        transform(req: Request, file: Express.Multer.File, cb: any) {
          if (imageMimeType.includes(file.mimetype)) {
            cb(null, sharp().jpeg());
          } else {
            cb(
              null,
              ffmpeg()
                .videoCodec('libx264')
                .audioCodec('aac')
                .outputFormat('mp4')
                .outputOptions(['-movflags frag_keyframe+empty_moov'])
            );
          }
        },
      },
    ],
  }),
});


  


  The image's part is working fine with Sharp, now I want to use fluent-ffmpeg to transform the video as well. I still can not figure out how to make the ffmpeg return a ReadableStream or Buffer so that it can be uploaded to S3 due to this code of multer-s3-transform :

  


    storage.getTransforms[i].transform(req, file, function (err, piper) {
  if (err) return cb(err);
  
  var upload = storage.s3.upload({
    Bucket: opts.bucket,
    Key: key,
    ACL: opts.acl,
    CacheControl: opts.cacheControl,
    ContentType: opts.contentType,
    Metadata: opts.metadata,
    StorageClass: opts.storageClass,
    ServerSideEncryption: opts.serverSideEncryption,
    SSEKMSKeyId: opts.sseKmsKeyId,
    Body: (opts.replacementStream || file.stream).pipe(piper),
  });


  


  Many thanks

  


• Invalid argument Unable to print text using drawtext using ffmpeg

  I am trying to add text and time stamp on video but not able to print the simple text on it.

  


  String[] complexCommand = {"-f", "3gp", "-i", videoPath, "-s", height + "x" + width, "-r",
 "17", "drawtext=fontfile='file://android_asset/font_eight.ttf':fontsize=20:text='test':x=10:y=100",
  "-vcodec", "libx264", "-vb", "2000k", "-preset", "fast", "-f", "3gp", dir.getAbsolutePath() + "/out.3gp"};
 
 ffmpeg -f 3gp -i /storage/emulated/0/DCIM/Camera/VID_20171211_105946.3gp -s 1920x1080
 -r 17 drawtext='fontfile=file://android_asset/font_eight.ttf:fontsize=20:text=test:x=10:y=100 
-vcodec libx264 -vb 2000k -preset fast -f 3gp /storage/emulated/0/Pictures/Video/out.3gp 


  


  — Edited Question ---

  


  Error :

  


  Fontconfig error : Cannot load default config file

  


  [Parsed_drawtext_0 @ 0xf5ba0730] impossible to init fontconfig

  


  [AVFilterGraph @ 0xf5b89040] Error initializing filter 'drawtext' with args 'fontfile=file ://android_asset/font_eight.ttf:fontsize=32:text=test:fontcolor=white:x=0:y=0'

  


  Error opening filters !

  


  Same command runs on windows with no error, But when I converted it for mobile device and tested getting error of font-path.
