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

0496a03413 simplify 
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

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

826ca10408 * gotta setup coded_frame for encoding. avcodec.h says that for decoding 
lavc is supposed to set it up as well and I don't think I see any
      reason not to.

99683a3077 2 byte shorter userdata for mpeg4 
in the past it was startcode,string,00,7F,startcode
now it is startcode,string,stratcode
both are mpeg4 compliant, as according to the standard the userdata lasts until the next 00 00 01 (startcode prefix) but some very primitive decoders which simply skip until the first 00 byte and then expect the next valid startcode might fail with the old variant, just a theory though (didnt test if quicktime can decode it now)

747a0554ea - made --extra-cflags option work on darwin 
- allow INTER4V macroblocks for FLV1 codec
- fixed issue in flv file format saving 8 mp3 frames per packet instead of 1
- fixed crasher in flv file format involving mp3 buffer handling
- added FLV1 codec support for swf file format (FlashPlayer6 or above
required) and made it default
- fixed broken mp3 support in swf file format
patch by (Tinic Uro <turo at macromedia dot com>)
