94/07/04 public release of version 1.1a=======================================94/07/04 sEfixed wrong frame rate comment in .par filesmpeg2enc.c:- fixed error message refering to wrong filename (argv[1] -> argv[2])putseq.c:- changed a .sxf to .syf94/06/30 public release of version 1.1======================================94/06/30 sEadded missing _ANSI_ARGS_ in motion.c, predict.c, stats.c94/06/28 sEidct.c:- removed short-circuit for even-coefficient-only case94/06/19 sEadded non-linear mquant (cfogg)conform.c:- allow profiles >= 8, in this case no conformance checks are  made, needed to create 4:4:4 sequencesstats.c:- added output of # and percentage of coded blocks- deactivated output of cbp, dct_type and motion vectors94/06/17 sE  cummulative changes since version 1.0supports 4:2:2 and 4:4:4 chroma_formatsupports field picturessupports dual prime motion vectorsmoved conformance checks to conform.ctighter conformance checksfdct.c:- modified rounding expression, this might reduce floating point  implementation dependency, which caused verify to report differencesidct.c:- see CHANGES.decodermotion.c:- moved macro block loop out of estimation routines- variance is now always computed (even for I pictures)- if no B pictures: estimate dual prime vectors- added field picture motion estimation routines- frame estimates returns all field vector estimations (needed for dual prime)- changed fullsearch search pattern from line scan order to outward spiral  (slightly faster when used with short-circuit dist1)- dist1 speed enhancements: unrolled inner loop, stop accumulation if  partial sum exceeds a given distancepredict.c:- several modifications for chroma_format, field pictures and dual primeputpic.c:- moved mquant 'moderation' to ratectl.c- several modifications for chroma_format, field pictures and dual primeputseq.c:- report correct numbers of I,P,B pictures to rate control (even for  first / last GOP)putvlc.c:- fixed wrong DCT coefficient limit checks for MPEG-1- added putdmv() for dual prime- added support for cbp = 0quantize.c:- added correct saturation of coefficientsratectl.c:- changed some variables from double to int- calculate spatial activities in advance- improved VBV delay calculations and checksstats:- added output of motion vectors and coded block pattern94/05/17 public release of version 1.0======================================94/05/15 cfogg- renamed zz to zig_zag_scan, zz2 to alternate_scan,  quanttab to default_intra_quantizer_matrix,  qscaletab to non_linear_mquant_table- additional comments94/05/15 sEstyle changes and some additional comments in all filesfdctref.c: - same PI guessing as in idctref.c94/05/12 sEname changed to mpeg2encodereadpic.c: - conv444to422 and conv422to420 now convert one component per call, not both   at the same time - changed subsampling filters to be based on those proposed by Cheung - added filter for MPEG-1 4:4:4 to 4:2:2 subsampling94/05/11 sEmpg2enc.c: - changed definition of sample rate from width*height*picture_rate   to horizontal_size*vertical_size*picture_rate - added display of version / copyright when called without parametersglobal.h: - added version[] and author[] strings (similar to the decoder)94/04/?? sEfirst preliminary alpha release
