New driver support (version 495.44)

Created by: fkortsagin

Please provide details about your environment (please complete the following information)

Nvidia driver version: [495.44]
GPU Model: [GTX 1070]
OS: [Archlinux]
I'm willing to participate in testing of new patch version
Latest NVIDIA driver 495.44 came out,since the latest supported NVIDIA Driver version for the patch is 470.74,did some tinkering of my own in both patch.sh and patch-fbc.sh by adding manually the 495.44 driver support in both and everything works now.Provided code for both files.Hope it helps! Code for patch.sh #!/bin/bash

halt on any error for safety and proper pipe handling

set -euo pipefail ; # <- this semicolon and comment make options apply

even when script is corrupt by CRLF line terminators (issue #75 (closed))

empty line must follow this comment for immediate fail with CRLF newlines

backup_path="/opt/nvidia/libnvidia-encode-backup" silent_flag='' manual_driver_version='' flatpak_flag='' backup_suffix=''

print_usage() { printf ' SYNOPSIS patch.sh [-s] [-r|-h|-c VERSION|-l|-f]

DESCRIPTION The patch for Nvidia drivers to remove NVENC session limit

   -s             Silent mode (No output)
   -r             Rollback to original (Restore lib from backup)
   -h             Print this help message
   -c VERSION     Check if version VERSION supported by this patch.
                  Returns true exit code (0) if version is supported.
   -l             List supported driver versions
   -d VERSION     Use VERSION driver version when looking for libraries
                  instead of using nvidia-smi to detect it.
   -f             Enable support for Flatpak NVIDIA drivers.

   -s             Silent mode (No output)
   -r             Rollback to original (Restore lib from backup)
   -h             Print this help message
   -c VERSION     Check if version VERSION supported by this patch.
                  Returns true exit code (0) if version is supported.
   -l             List supported driver versions
   -d VERSION     Use VERSION driver version when looking for libraries
                  instead of using nvidia-smi to detect it.
   -f             Enable support for Flatpak NVIDIA drivers.
