From: Deb Mukherjee Date: Sat, 5 Apr 2014 00:30:16 +0000 (-0700) Subject: High-level hooks for Profile 2 (10/12 bit) X-Git-Tag: v1.4.0~1868^2 X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d35df2d8eaa74d7f9640f380f23e057fd7d83c35;p=libvpx High-level hooks for Profile 2 (10/12 bit) Adds some high-level hooks for profile 2 before further progress on the implementation. According to the definitiion in this patch: 1. Profile 2 only supports 10 or 12 bit color but not 8 2. Profile 2 supports all color sampling modes: 444, 422 and 420, and alpha plane. 3. Profile 3 is currently undefined. Please consider the definition carefully and suggest modifications to the definition as needed.
