Powershell Script to list ALL videos in your 365 Stream environment

I hope this is useful to everyone. 

My goal was to get a list of all videos in my stream so that I could contact each video creator about the changes that are coming to stream. Also so I could figure out how much work there was to do in moving, and how much video is created and not used.

My original solution (posted here 7 Oct 2020) I've retired, as thanks to Twan van Beers code here https://neroblanco.co.uk/2022/02/get-list-of-videos-from-microsoft-stream/ I've been able to build a single ps1 script that does all I need. I'll leave the the original code at the bottom of this post.

Take a look a the comments I've put into the code for how to use this script.

I found that my original script gave me information about the videos but it was hard to use AND didn't tell me which videos were in which channels. This new version of Twan van Beers script gives me both.

Save the new code Oct 2022 as a PowerShell script e.g. get-stream-video-info.ps1 Then open a powershell screen, navigate to the folder get-stream-video-info.ps1 is in. 

To run it enter    .\get-stream-video-info.ps1 "C:\Temp\streamanalysis\stream7Oct22-getnbstreamvideoinfo.csv"

Follow the on screen prompts.

>>> New Code Oct 2022 <<<

using namespace System.Management.Automation.Host

[CmdletBinding()]
param (
    [parameter(Position=0,Mandatory=$False)] 
    [string]$OutputCsvFileName,

    [parameter(Position=1,Mandatory=$False)] 
    [switch]$OpenFileWhenComplete = $False
)


# ----------------------------------------
#	How to use
<#--
	Open a powershell window then type in the following and click enter
		.\get-stream-video-info.ps1 "C:\Temp\streamanalysis\stream7Oct22-getnbstreamvideoinfo.csv"
		
	You'll then be prompted for 3 options
	[V] Videos  [C] ChannelVideos  [A] All  [?] Help (default is "V"): 
		V - videos, which will get a list of all the videos in your STREAM environment.
			NOTE you may need to alter the variables in the code if you have more than 1000s of videos
		C - ChannelVideos, will get a list of all the videos and the channels they are in.
			NOTE this returns a filtered view of all the videos associated with a channel
		A - All, returns both the Videos and the ChannelVideos.
		
	You'll then be prompted for a user to login to the STREAM portal with, this is so the script can get a security token to do it's work with.
	Choose/use an account with full access to STREAM.
		
	If you used a CSV file path after the script name, then this powershell script will export one or two CSV files based on the option chosen
		<your folder path, your filename>-videos<your file ending>
		and or
		<your folder path, your filename>-channelVideos<your file ending>
			
	If you don't want to export file names, this powershell creates objects you can use in other ways
		V or A - will create an object $ExtractData, which is a list of every video and key properties for each video.
		C or A - wil create an object $videosPerChannel, which lists key information about each video AND the channel they are part of.

	original source
	my script 
	https://techcommunity.microsoft.com/t5/microsoft-stream-classic/powershell-script-to-list-all-videos-in-your-365-stream/m-p/1752149

	which inspired Twan van Beers to write
	https://neroblanco.co.uk/2022/02/get-list-of-videos-from-microsoft-stream/
	
	I've then taken Twan's script and modified it to do what I require in my environment.
	Namely - get the video information AND the channels they are part of. For my 1000 or so videos and 35 channels, it takes about 1 min to run using the All option.
	
	This meant I was able to setup an intranet video library with a channel metadata column, folders per channel 
	(so i could give edit rights to channel owners, without opening up the entire library or having to use multiple libraries), and eventually
	download the videos, then upload them into the library using ShareGate to reinstate some of the key metadata, i.e. created date, person who created them etc

I've left this here in case it is useful to anyone. See the script above for a better solution.

That said this solution relies on you knowing a bit about PowerShell, being a Stream Admin and being happy to manually save some files (I couldn't figure out how to do pass through windows authentication for the script) so you have to manually save each paged JSON file of 100 videos.

It took me about 20minutes to export information about 591 videos (about 3 hours to make the script).

To use the script

• update each variable marked with #<<<< Update this value
• in a normal (not admin) powershell window run the script (i copy and paste logical parts into the powershell window)
• you will be given several urls, to visit and save the JSON files from
• once you have the JSON files the final part of the script reads those, and exports a CSV file with a row per video in STREAM

NOTE : as an admin you see all videos, so before you share the CSV with others be aware that there may be sensitive information in it that most users can't see due to STREAM's in built security.

I don't have much time, hence I made this script so please don't expect quick answers to any questions. This script is rough, use it if it helps, but ... be professional and check it before you use it.

##>> Update 5 Aug 2021 <<##

Thanks to everyone who has commented, I've updated the code below with your suggestions

You still have to manually save the JSON browser tabs that show up as JSON files into a folder, but other than that I hope it is now easier for you to use 🙂

#First

# using Developer tools look at the "console" search for .api.microsoftstream to find out what is between https://  and     .api.microsoftstream in my case    https://aase-1.api.microsoftstream.com/api/

#[string]$rootAPIlocation = "uswe-1" 	# use this for Western US
#[string]$rootAPIlocation = "euno-1" 	# use this for the Europe North region
