d705e4a6bb (f)printf() is disallowed in libavcodec, compilation will fail now if its used, except that codecs which where added after the printf->av_log change which did ignore av_log() and used prinf are now silent and wont print anything, they should be changed to use av_log, i could do that, but its better if the orginal developer decides which AV_LOG level each message should get

2451592652 improved VCD support patch by ("Hauke Duden" <H.NS.Duden at gmx dot net>) 
- the first audio and video packs now contain only a system header and lots
  of padding.
  - no system headers in any packs other than the first ones
  - the two system headers only contain information about "their" stream
  - fixed some header values (muxrate, some flags, ...) so that they have the
  values specified by the standard
  - padding packs are inserted if the mux rate would be below 75 packs per
  second (the rate must not be below or above that value).
  - fixed the SCR of the packs
  - 20 zero bytes are now inserted at the end of each audio pack, after the
  data packet

only change context if frame header is error-free, as some fields may not be stored in the frame header and so a single damaged frame-header may trash them

channel_order -> decorrelation_type (cosmetic i know, but the old name is too meaningless IMHO)

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

9c3d33d67f multithreaded/SMP motion estimation 
multithreaded/SMP encoding for MPEG1/MPEG2/MPEG4/H263
all pthread specific code is in pthread.c
to try it, run configure --enable-pthreads and ffmpeg ... -threads <num>
the internal thread API is a simple AVCodecContext.execute() callback which executes a given function pointer with different arguments and returns after finishing all, that way no mutexes or other thread-mess is needed outside pthread.c
