From 1a5bac2149fa2c6224b40c0b40839c2025414e79 Mon Sep 17 00:00:00 2001 From: Grigori Goronzy Date: Wed, 9 Oct 2013 02:23:50 +0200 Subject: [PATCH] st/vdpau: fix GenerateCSCMatrix with NULL procamp MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit As per API specification, it is legal to supply a NULL procamp. In this case, a CSC matrix according to the colorspace should be generated, but no further adjustments are made.
