I was following this tutorial RaspBerry Pi webcam 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. 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 use 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

Did you build anything from source, or are these all maintainer-supplied packages? In the latter case, file a bug report. –  nneonneo Sep 21 '12 at 11:05
