+    media/gpu/v4l2: Only set HEVC .num_delta_pocs_of_ref_rps_idx on ChromeOS
+    
+    The HEVC decode parameter .num_delta_pocs_of_ref_rps_idx field was
+    very recently added to support MediaTek's stateless HEVC decoder. It
+    was accepted upstream, but hasn't been part of a release yet, and so
+    hasn't trickled down into a distro package that can be included in the
+    sysroots.
+    
+    Guard the field assignment for now so that the Linux builds can proceed.
+
