• Setting up a server to redistribute a webcam stream

  22 janvier 2013, par Martin Taleski

  I am trying to set up a streaming server that will receive a RTP stream and redistribute it.

  I am able to create the stream with :

  ffmpeg -f video4linux2 -i /dev/video0 -vcodec mpeg2video -r 25 -pix_fmt yuv420p -me_method epzs -b 2600k -bt 256k -f rtp rtp://myserver:8090/

  I see the UDP packets coming to my server, but I was not able to set up a feed and a stream with ffserver. I can also view the stream though VLC if I change the destination IP of the server with my local IP.

  I am now considering writing a daemon in python or perl or C, that will read the UDP packets coming on port 8090 on the server, and distribute them on another port. Not sure if this is a great idea, but can not find any other clues...

  Any clues how to make this happen ?

• setTimeout() fix for onfinish()-related issue where subsequent play() calls fail when Flash Player 11.6.602.171 is installed, and using soundManager with flashVersion = 8 (which is the default).

  setTimeout() fix for onfinish()-related issue where subsequent play() calls fail when Flash Player 11.6.602.171 is installed, and using soundManager with flashVersion = 8 (which is the default).
  Not sure of exact cause. Suspect race condition resulting in an invalid (NaN-style) position argument trickling down to the next JS -> Flash _start() call.
  Fix : setTimeout() to yield, plus safer null / NaN checking on position argument provided to Flash.
