Summary: real encoder improvements 

Initial Comment:
2001-04-07  Peter Schlaile <ud...@rz...>
        * VLC encoder improvements: static qno tables
for 3 passes
        * audio support for the encoder (plugin system
with wav and /dev/dsp
          support)
        * renamed build_coeff to fill_macroblock and
moved it into the
          input filter. Wrote specialized mmx copy
routines. 
          -> now we _are_ realtime on an Athlon 800
even with 3 VLC passes 
          (static qno tables!) It's time to throw the
video recorder away ;-)
        * New option: --fps : select frames per second
if your machine isn't
          fast enough for the full bandwidth
        * Interface changes: -t renamed to -v since it
gives additional
          verbose output now.
        * pgm support for mpeg2dec

        * VLC encoder improvements: Now it's more
correct for 3 passes (but
          also slower...), faster for 2 passes.
Implemented turbo mode 
          (static qno tables). Hopefully makes the
thing finally realtime on 
          an Athlon 800...
        * Separated out the input and output queue.
Build general input and
          output filter plugin system. Included
/dev/video support.
        * several assembler optimized routines in the
vlc encoder added, 
          reorder_88 code is now merged with the DCT
postscaler to fill the 
          integer pipelines _and_ the MMX pipelines
        * renamed encode to encodedv
        * removed blur function since it doesn't make
sense
        * corrected (?) faster C version of
convert_to_yuv
