The ogg2 demuxer doesn't call any codec directly.  It's
av_find_stream_info() that does it once to figure out the stream
parameters, even if the stream later goes unused, and then ffmpeg
opens the codec as required.  The reason you're noticing this with ogg
files is that the theora decoder prints a message on initialization.
The fix: remove that message ;-)
