• Setting up multi webcam streaming

  28 septembre 2013, par Moritz Mädler

  we are currently planning to connect all our offices via webcams selectable from a website. So I guess the setup could be something like this :

  Webcam 1 \
  
  Webcam 2 - > Streamserver -> Webserver displaying html5 Video 
  
  Webcam n /

  I've made first tests from streaming from Windows using VLC to a central ffserver, but the results where rather bad (after 1-2 frames the stream stopped).

  Do you have any suggestions on
   which stream software I can use on the client/webcam site (Linux or Windows)
   which software I can use on the server side (Linux) for collecting and recoding streams ?

  Thanks,

  Moritz

• Try to close SDL_CloseAudio has deadlock when RTSP server is down

  24 juillet 2014, par Evan Lin

  I try to using live555(a.k.a OpenRTSP) to setup RTSP server and client.
  My Client application using live555, ffmpeg and SDL as streaming, decode and playback.
  

  I found it might have deadlock if I try to call SDL_CloseAudio as following situation :

  • When RTSP is down.
  • When network is broken.

  I am exclude it related to any timing issue because it works well if I try to call SDL_CloseAudio when server is not down.

  Also, I have tried following API but still not work :

  • Try SDL_PauseAudio before close it.
  • Try SDL_UnlockAudio before close it.

  Any idea for this ?
