• How to import fluent-ffmpeg in aws lamdba ?

  3 octobre 2019, par Fook

  I’m trying to use fluent-ffmpeg in AWS Lambda, but cannot get it setup correctly. At the top of my index.js :

  import ffmpeg from "fluent-ffmpeg";

  But it is always undefined.

  ffmpeg === undefined.

  I’m using Serverless and have ffmpeg included as a layer.

  serverless.yaml

  functions:
  
    createGifFromVideo:
  
      handler: src/services/createGifFromVideo/index.handler
  
      layers:
  
        - { Ref: FfmpegLambdaLayer }
  
      events:
  
        - sns: arn:aws:sns:us-east-1:${self:custom.accountId}:NewVideoPostContentTopic-${self:provider.stage}
  
  
  
  layers:
  
    ffmpeg:
  
      path: src/layers

  package.json

  {
  
    "name": "createGifFromVideo",
  
    "version": "1.0.0",
  
    "main": "index.js",
  
    "license": "MIT",
  
    "private": true,
  
    "dependencies": {
  
      "fluent-ffmpeg": "^2.1.2"
  
    }
  
  }

  The uploaded lambda seems to be constructed correctly from what I can tell. Webpack builds the file with fluent-ffmpeg merged in and it is linked to the ffmpeg layer.

  I can load other packages. It’s just fluent-ffmpeg that comes back undefined.

  From the docs it mentions passing FFMPEG_PATH and FFPROBE_PATH as environment variables. Are these necessary with a layer ?

  I would be grateful to see a configuration that works.

• Web Based Playback of iOS Videos with Orientation Flag

  3 mars 2012, par shanee

  We just recently created an iPhone app for one of our system that allows users to upload picture and video content to our services. The last major hitch we are running into is how to handle videos that are uploaded in an orientation other than Horizontal Right. Apparently if your playback system does not account for the orientation flag sent with the video then it will play upside down or sideways.

  The correct approach appears to be that the playback system should take the orientation flag into account just prior to playback. This is the way Apple handles it directly on the device as well as through Quicktime.

  SO my first hope is that someone is aware of a web based (HTML5 or Flash) player that is capable of rotating a video during playback based on either the video orientation metadata or based on a passed flag (we already have the necessary flag available in the DB if we need to just pass it manually). If you know of any such player then PLEASE SHARE !

  If you aren't aware of such a player, then has anyone had any luck rotating their videos using FFMPEG or MEncoder ? We did a few hours of testing last week and weren't able to get any decent results from the two heavy hitters mentioned there.

  Failing ALL OF THAT, is it possible to have the iPhone upload a video or image in a specified direction ?

  Any of the three will work for me, but I would prefer to do whatever is standard (if one exists).

  Any help is much appreciated !
