From f6b8af22e9aab21d72c881f5eebfb8eef805ac88 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 24 Apr 2015 11:16:26 -0300 Subject: [PATCH] [media] vivid-tpg: fix XV601/709 Y'CbCr encoding For these encodings the quantization range should be ignored, since there is only one possible Y'CbCr encoding.
