fix ffmpeg locking issue

ffmpeg complained "insufficient thread locking around avcodec_open/close()".
This was caused by encavcodec.c calling avcodec_open at the same time as
stream.c called av_find_stream_info.  av_find_stream_info has a side effect
of calling avcodec_open, so we must lock around this call as well.
