• Is there any library in python or can we use FFMPEG to detect the appearance of the lines pattern in video that is shown in the image attached below ? [closed]

  Video defect appearing frame

  


  Hi All,

  


  I am trying to find a way to detect the appearance of this lines pattern embedded in the link below.
If I get any match of this pattern in a video, I need to record that particular timestamp of the video where I got the pattern match.

  


  My idea is to take the image and compare it against the video to find for approximate match percentage. If I get it, then I record that particular timestamp within a .txt file.

  


  Is there any better way to achieve this ?
I think we can use Python or FFMPEG video filters to get a solution for this.

  


  It would really help if anyone can support with a solution. Thanks

  


  Update :
I got a reference where they have proposed a solution similar to my concern.

  


  https://aws.amazon.com/blogs/media/metfc-automatically-compare-two-videos-to-find-common-content/

  


  So we can try to achieve some output from this solution.

  


• How do I use a buffer object as Ffmpeg's source input

  6 septembre 2016, par Marwan Sulaiman

  I’m using node.js as a web server (fluent-ffmpeg as the ffmpeg library).

  1. I have two videos on amazon s3, when I retrieve them, they come as Buffer objects.

  2. I’d like to retrieve them, combine them, and send them to the client, without having to save them as files.

  I am trying to generate thumbnails from videos in an S3 bucket every x frames by following this documentation : https://aws.amazon.com/blogs/media/processing-user-generated-content-using-aws-lambda-and-ffmpeg/

  


  I am at the point where I'm testing the Lambda code provided in the documentation, but receive this error in CloudWatch Logs :

  


  

  


  Here is the portion of the Lambda code associated with this error :

  


  

  


  Any help is appreciated. Thanks !
