Hello,

Here are my libav* libraries :
Qt Code: 
  1. /usr/local/lib$ ls -al libavcodec*
  2. -rw-r--r-- 1 root root 90588642 mars  25 15:32 libavcodec.a
  3. lrwxrwxrwx 1 root root       23 mars  25 15:32 libavcodec.so -> libavcodec.so.54.23.100
  4. lrwxrwxrwx 1 root root       23 mars  25 15:32 libavcodec.so.54 -> libavcodec.so.54.23.100
  5. -rwxr-xr-x 1 root root  7527520 mars  25 15:32 libavcodec.so.54.23.100

I tried to run sudo apt-get update && sudo apt-get upgrade but it didn't solve the problem.
I guess my version of livav* is wrong, which one should I use ?
