libmpcodecs: add ad_spdif.c, S/PDIF passthrough decoder
patch by Naoya OYAMA, naoya.oyama gmail com git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@34191 b3059339-0415-0410-9bf9-f77b7e298cf2 fix ad_spdif Call av_register_all() before initialising the SPDIF muxer. Fixes playback with -demuxer mpegts -ac spdifac3. Patch by Naoya OYAMA, naoya D oyama gmail git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@34291 b3059339-0415-0410-9bf9-f77b7e298cf2 Use new API avformat_new_stream() instead of the deprecated av_new_stream(). Patch by Naoya OYAMA, naoya D oyama gmail git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@34292 b3059339-0415-0410-9bf9-f77b7e298cf2 Cosmetics: Remove empty statement.
