• Get image from webcam, convert that image into something else, and returning it back to the client

  29 janvier 2023, par immigration9

  I have some questions on choosing the right architectural decision to solve my problem.

  


  I am planning to create an app, which takes the

  


  


  1. input from a client's (a browser) webcam,

     


  


  2. sending the input to the server (whether frame by frame, or just live stream video)

     


  


  3. getting each frame from the server (into a image)

     


  


  4. convert the image using some technology (let's say like a tiktok filter)

     


  


  5. returning the image back to the client in real time.

     


  


  


  Except for the phase 4 which the technology can only be applied on an image,
Everything else can be changed.

  


  I'm targeting 30fps (or at least 20) with 1080p quality.

  


  The language or framework is completely agnostic as I do not have any preference. Right now, I am thinking of using React with Node, but I'm opened to other options as well. (eg. Python maybe. Language doesn't matter)

  


  If anyone have some prior experiences, can you teach me the best way ?

  


  I've tried to create the image blob from client and send it to the server using socket.io but it seemed too slow to use when targeted at 30fps on 1080p image.

  


  I'm currently looking at WebRTC with fluent-ffmpeg, but not sure if it's the right way.

  


  Any kind of help will be appreciated.

• Live streaming HLS via ffmpeg, How to force client to start playing from the beginning ? From 1st segment

  27 janvier 2021, par vedeojunky

  Is there a way, maybe via an ffmpeg option or flag, to force the client player to always start the playlist from the beginning when live streaming rather than the real time mid-stream ?

  



  Say the user comes in 1mn after the stream has started, rather than starting to watch at 1mn the player would start at the beginning of the video so minute zero.

  



  Here is my ffmpeg command :

  



  ffmpeg -f "screen capture" -s 1280x720 -r 30 -i :0.0+nomouse -f alsa -ac 2 -i pulse -async 30 -vcodec libx264 -pix_fmt yuv420p -acodec libfdk_aac -ar 44100 -b:a 64k -threads 0 -s 640x360 -f hls -g 1 -hls_time 1 -hls_list_size 1 -hls_allow_cache 0 /hls/#{@stream_name}/index.m3u8


  



  Thanks !
