I didn't try your patch, but I'm extremely sure it doesn't compile. You
forgot a lot of stuff in the first av_log() call line.

Please, when creating a patch:
- branch locally from master
- do your edits
- try to compile
- fix by editing again
- compile
- test your change
- repeat if necessary
- commit locally
- create a patch from this commit with git format-patch
- submit the patch.

And please fix your email address when committing.
