Michael Niedermayer	f5a719287d	rescale coefficients during IDWT, that way the lifting steps are much simpler and faster Originally committed as revision 4119 to svn://svn.ffmpeg.org/ffmpeg/trunk	20 years ago
Michael Niedermayer	a0a74ad9f0	increasing precission of the quantization parameter this is needed as the quantization stepsize for each subband is also in this precission and insignificant changes to the wavelet like scaling its coefficients slightly differently would lead to wildly variing PSNR and bitrate note, a encoder could also simply choose to leave the least significant bits of the quantization parameters zero which would give the exact previous behaviour except a y very tiny number of bits in the header Originally committed as revision 4115 to svn://svn.ffmpeg.org/ffmpeg/trunk	20 years ago
