ffmpeg messages go to stderr, not sure what happens on Windows.
try vlc --ffmpeg-debug option?

thanks for your sugguestion. actually I have tried this way. my test steps are:
1. cross compile vlc and all contrib on ubuntun for windows. make package-win-common. vlc-2.1.0
2. copy vlc-2.1.0-git to win7.
3. run vlc in command console, like: vlc --ffmpeg-debug=3 test.avi. it will pop up a vlc player windows, but command console there aren't debug message. 
and I have tried to run vlc -vvv, open logger interface in vlc player, in the logger windows can get vlc message, not ffmpeg log.

best regards,
