From 60f0fde3092d18d4d36555962c192af8691a099c Mon Sep 17 00:00:00 2001 From: Vittorio Giovara Date: Thu, 28 Jan 2016 11:38:27 -0500 Subject: libx264: Make sure to preserve default option values The private options chromaoffset, sc_threshold, and noise_reduction were set to 0 rather than -1, and were always initializing values in libx264 rather than letting the library use its default.
