• How do IP camera stream video across home network

  22 janvier 2018, par Ouroboros

  My question is how do the IP camera stream the data from home network to public network. Here’s how I think it can be done :

  1. If I’d to set up something like this using a raspberry pi camera module. I’d probably use port forwarding on my Access Point/Wifi Router. However, clearly, this is not a scalable solution, and there must be something else that off the shelf IP cameras must be doing.

  2. One option is to stream the video (using ffmpeg) to a remove server, and then that remote server can probably again "re-stream" that ? -If this is indeed the case, how is it done ?

  I understand backend architecture very strongly, and have developed fairly complex onces so I do want a fairly technical answer for this one.

• Hls media playlist request url override

  16 janvier 2018, par Tomasz Kowalczyk

  Trying to implement hls support on my platform build with laravel. Testing both ffmpeg and AWS Elastic transcoder solutions. The problem is that i’ve got custom url for requesting files for security purposes. That url then returns the hls master playlist, but subsequent request for media playlists has wrong url. This is because the paths in master playlist are not absolute. I tested it with absolute paths and it worked, but I changed the paths manually, can’t see it as an option on AWS Elastic Trancoder, and not tested it yet on ffmpeg package. I’m not really sure what generates the subsequent request for the media playlists ? Is it the video player or hls codec/plugin ? Can i tinker the original response headers to modify the subsequent requests ? Or am I going the wrong way about it ?
  Any help would be greatly appreciated.

• Problems with slowing down when grid synthesis operation request via ffmpeg is received simultaneously

  7 novembre 2022, par bongcheol Kim
  

  1. Crop/scaling/volume leveling encoding of videos uploaded by users in S3 with predetermined settings

  


  2. Synthesize in grid form with other pre-prepared videos.

  


  


  Perform the above tasks through ffmpeg.
Encoding slows down when multiple requests occur simultaneously.
(Maybe it's because we shared the server's resources.)

  


  To process task requests from 1 and 2 at the same time, but to process them
What can I do ?

  


  Is there a service on AWS that can solve my problems ?

  


  I thought about creating and processing ec2 individually for each request, but is this possible ?

  


  

  1. Invoke API

  


  2. Create EC2

  


  3. Proceed with one encoding operation on the corresponding EC2

  


  4. Delete EC2 after uploading s3
