• Efficient way to stream a sequence of frames

  3 juin 2020, par DoriHp 0

  I'm facing with an issue : I implemented a device to detect stranger for my home, which includes inputs from some IP camera and use a tensorflow model to process frame got from them.

  



  Now I want to build a dashboard (use Flask or Django - python framework as backend) to streaming the processed frames I got from the system, and if possible, do some transform on them (such as stack multi frames into one, etc), and run the server so I can watch it from distances. Currently, I'm sending frame by frame as independent images but it costs so much bandwidth. I read how h264 encoder work and felt very exicted about it. Now, the question is, how can I use h264 or any encoder like it transfer my data and reduce the bandwidth ?

  


• What is the point of encrypting HLS files ?

  29 janvier 2016, par APITC

  I am currently working on a project of videos on demand where I convert videos to HLS using FFMPEG.

  Videos are publicly hosted on AWS S3 and there is an API giving the URL of the HLS playlist.

  Now, I was looking at encrypting HLS files with AES-128 so that people can’t download and watch the video offline.
  I found the procedure which consists in hosting the key online and using that key while converting the video to encrypt the segments.

  The URL of the key is written in the HLS playlist, and the file is publicly available online.

  So anyone has access to the encryption key.

  I don’t understand what is the point of encrypting the segments if anyone has access to the key.

  Can someone enlighten me ? I know I must be missing something. Thanks !
