Rémi Denis-Courmont	9135dffd17	lavc/h264dsp: reduce spills in R-V V idct_add16	6 months ago
Rémi Denis-Courmont	245f76ad74	lavc/h264dsp: reuse the R-V V IDCT DC add functions This reuses the DC bypass functions from the multiple IDCT functions, to leverage vector code. As an added bonus, the caller functions can now rely on the callee functions to preserve their parameters, thus cutting down on stack spills.	6 months ago

Mark Thompson	7110a36ba0	cbs_av1: Reject thirty-two zero bits in uvlc code The spec allows at least thirty-two zero bits followed by a one to mean 2^32-1, with no constraint on the number of zeroes. The libaom reference decoder does not match this, instead reading thirty-two zeroes but not the following one to mean 2^32-1. These two interpretations are incompatible and other implementations may follow one or the other. Therefore reject thirty-two zeroes because the intended behaviour is not clear.
