• malloc error ubuntu ffmpeg server not streaming

  21 septembre 2012, par user1509326

  enter code hereI was following this tutorial http://jeremyblythe.blogspot.com/2012/05/raspberry-pi-webcam.html and when i run the following command from root

  ffserver -f /root/ffserver.conf & ffmpeg -v 2 -r 5 -s 640x480 -f video4linux2 -i /dev/video1` http://localhost:8090/webcam.ffm
  

  The camera is turned on and everything is fine, except it does not stream, i checked the terminal and it says the following.

  from video 1 i get the following error
  bind(port 8090): Address already in use
  *** glibc detected *** ffmpeg: malloc(): smallbin double linked list corrupted: 0x0000000000e5ac00 **
  

  when i another port like 5000 i get the same result

  ffserver -f /root/ffserver.conf & ffmpeg -v 2 -r 5 -s 640x480 -f video4linux2 -i /dev/video1 http://localhost:8090/webcam.ffm
