Subject: Disable i8x8 in lossless
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=af8e768e2bd3b4398bca033998f83b0eb8874914;p=libx264

Disable i8x8 in lossless

x264's implementation was slightly incorrect due to a vague spec, so some
decoders decoded video incorrectly.

Minimal impact on compression.
