• Installation of opencv and ffmpeg on anaconda

  17 mars 2017, par user564650

  I am using an amazon EC2 instance and working on a deep learning problem. I want to install opencv along with ffmpeg on anaconda python in order to process the video frames. Can somebody please help out with the installation ?

• 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.

  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.
