Michael Niedermayer	bacc4b6e81	avcodec/wmalosslessdec: Use unsigned operations for overflowing cases Fixes undefined behavior in fate-lossless-wma24-2 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Christophe Gisquet	7d453aaf65	wmalossless: allow calling madd_int16 This is done by actually handling the "prev_values" in the cascaded LMS data as if it were int16_t, thus requiring switching at various locations the computations.	9 years ago
Michael Niedermayer	3187277ebb	avcodec/wmalosslessdec: Fix memset sizeof Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Christophe Gisquet	532e937083	avcodec/wmalosslessdec: silence a sample request 16bits samples with CDLMS orders of 8 are currently unsupported, but have never been encountered before. However, 8 seems to be the most frequent, if not the only order used for 24bits. In that case, the dsp functions are fine with handling order that are multiples of 8, so silence the warning.

Christophe Gisquet	adf4ee40e7	wma lossless: reuse scalarproduct_and_madd_int16 This is done by padding the coefficient buffer with 0s, because the order may be only a multiple of 4, and the DSP function requires batches of 8. However, no sample with such a case was found, so request one if it uses that kind of order.
