How to apply patch in CentOS 8

Hello

I am trying to compile libva-utils package in CentOS 8. Since it is not available in CentOS 8 repo, I'm using EL7 package to compile it. But I don't know how to apply patches.

Steps I followed:
1. Downloaded srpm from https://download-ib01.fedoraproject....-4.el7.src.rpm
2. Extracted it using command 'rpm2cpio libva-utils-1.8.3-4.el7.src.rpm | cpio -ivd'
3.Extracted files listing
Code:ls -1
0001-vainfo-add-an-option-device-to-specify-a-drm-device.patch
0002-vainfo-Add-help-to-show-available-options.patch
libva-utils-1.8.3.tar.gz
libva-utils.spec4. Contents of libva-utils.spec
Code:Name: libva-utils

Code:# yum install libtool libXext-devel libXfixes-devel libdrm-devel libva-devel wayland-devel pkgconfig6. Now I've to apply patch and compile the source. But I don't know how to apply patches as specified in point 4

I really appreciate if someone tells me how to apply those two .patch files

Thanks
