.Synopsis
   iDRAC cmdlet using Redfish API with OEM extension to export either boot capture videos or crash capture video locally.
.DESCRIPTION
   iDRAC Cmdlet using Redfish API with OEM extension to export either boot capture videos or crash capture video locally. NOTE: iDRAC copies boot capture videos to a zip file and prompts you to download using your default browser. If needed to watch the video capture files (dvc format), download the video player from the iDRAC GUI/Maintenance/Troubleshooting page.
 
   Supported parameters to pass in for cmdlet:
    
   - idrac_ip: Pass in iDRAC IP
   - idrac_username: Pass in iDRAC username
   - idrac_password: Pass in iDRAC password
   - x_auth_token: Pass in iDRAC X-Auth token session to execute cmdlet instead of username / password (recommended)
   - filetype: Pass in the filetype to export. Supported string values are BootCaptureVideo or CrashCaptureVideo
    
.EXAMPLE
   Invoke-ExportVideoLogREDFISH -idrac_ip 192.168.0.120 -idrac_username root -idrac_password calvin -filetype CrashCaptureVideo
   This example will export iDRAC crash video capture to a zip file and prompt you to download the zip using your default browser.
.EXAMPLE
   Invoke-ExportVideoLogREDFISH -idrac_ip 192.168.0.120 -filetype CrashCaptureVideo
   This example will first prompt for iDRAC username and password using Get-Credentials, then export iDRAC crash video capture to a zip file and prompt you to download the zip using your default browser.
.EXAMPLE
   Invoke-ExportVideoLogREDFISH -idrac_ip 192.168.0.120 -filetype CrashCaptureVideo -x_auth_token 7bd9bb9a8727ec366a9cef5bc83b2708
   This example using iDRAC X-auth token session will export iDRAC crash video capture to a zip file and prompt you to download the zip using your default browser.
