Michael Niedermayer	ac2570a8b0	flac fixes: ... fix data types of residual&decoded fix twos complement bitfields fix utf8 (no, utf8 is not the same as the simple and compact uvlc used in nut) add truncated bitstream support, both ogg and flac demuxers in mplayer cvs provide incomplete frames, and furthermore it isnt possible to find frameboundaries in flac without decoding it completly add escape-less golomb rice decoder (=flac style golomb rice) (ultra efficient, the longest vlc code is just 2^32-1 bits) printf->av_log fix bps for non independant channels fix a few +-1 bugs fix sample order for independant channels fix data_size Originally committed as revision 2791 to svn://svn.ffmpeg.org/ffmpeg/trunk	2004-02-18 01:49:30 +00:00
