If you upgrade to a more recent version of the FFmpeg library, thread locking
should not be necessary.
I use a version from January 2010, and have no thread locks around the FFmpeg
library calls.
If you don't have error, it's just because you are lucky or you don't access
avcodec_open/close concurrently.
avcodec_open/close require locking in the svn trunk HEAD (the most update to
date version) but as I said, providing a lock manager function is enough to
prevent race conditions
I was not aware this was a problem, but I see the warning in avcodec.h
now that I look for it.
Thanks for the information,
