Cannot stream webcam using ffserver because of malloc error [migrated]
21 septembre 2012, par user1509326I 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

Increase the bitrate tolerance of ffmpeg for creating screenshots of a movie
21 septembre 2012, par rekireI'm getting the error
bitrate tolerance too small for bitrate
so far no problem. I know that there are several switches to increase that but nothing works.ffmpeg -y -r 1/30 -b:v 999999k -bt 999999k -maxrate 999999k -i in.flv out%03d.jpg
The source of that commandline is directly from ffmpeg. But that crashes :
