• want to stream mobile camera using ffserver and ffmpeg

  6 janvier 2017, par Vinay Pandya

  First i will tell you my requirement than i will tell you what i have done.

  i am noob in media streaming i am learning and i am very confused about it.

  basically i want to do following thing

  1 : mobile app will stream video on server through URL (which is on my laptop)
  2 : My laptop should run ffserver/ffmpeg which store video stream which is coming from mobile app and allow other client to watch it (here i am talking about VLC as client).

  so this is my requirement.

  i ham running ffserver on my laptop

  my ff server config is like :

  HTTPPort 8090
  
  HTTPBindAddress 0.0.0.0
  
  
  
  RTSPPort 8091
  
  RTSPBindAddress 0.0.0.0
  
  
  
  
  
  MaxHTTPConnections 2000
  
  MaxClients 1000
  
  MaxBandwidth 1000

  i am not able to watch that live stream on VLC client. also tell me what URL should i enter in VLC for streaming i have tried almost every url combination.
