From 458c13ae10e72901a2420cb546b183daae102984 Mon Sep 17 00:00:00 2001 From: Jernej Skrabec Date: Wed, 9 Nov 2022 19:23:09 +0100 Subject: [PATCH] media: cedrus: Relax HEVC SPS restrictions Testing reference video TSUNEQBD_A_MAIN10_Technicolor_2 has show that Cedrus is capable of decoding frames with different chroma and luma bit depths. Relax restrictions so only highest depth is checked.
