DEPENDENCY

• cURL

Why?

There is no official interface yet it is a rudimentary task for anyone administering such a video platform to be aware of pending, working or missing video streams.

SYNOPSIS

Write env variables first

1. M_AUTH

2. Open the Mediasite catalog in your favorite browser

3. Alter the catalog URI to /Mediasite/Manage and log in

4. From browser debugger copy MediasiteAuth cookie or inspect any XHR request for Cookie HTTP header

5. M_HOST

Mediasite Enterprise Video Platform Application (EVP) server FQDN like mediasite.example.com

Run mQuery like this

( source auth.env && perl mQuery.pl --streams |tee mediasite.txt )

STREAMS

Filter out streams

• grep -v [MP4] mediasite.txt to list presentations missing an MP4 stream
• grep [OCR:bad] mediasite.txt to list presentations with a pending OCR
• grep [PLAYBACK:bad] mediasite.txt to list presentations with a broken playback (experimental)

NOTES on audio

• Always check for not assigning a dummy audio interface (Recorder issue)

  Except a visual check there is no way to find a presentation is silent as for a Completed video stream there is always an audio layer present. And you cannot find about the audio size (length) unless you would download and demux the whole video file.

RELEASE NOTES

mQuery wraps cURL requests around several Mediasite JSON URIs. Additionally it can be made to verify presentations for Status (Viewable/Scheduled/..), State (Completed/Pending/..) or Player (Multiview/Full experience/..).

• Tested for Mediasite Server Version 7.0.30 Build 3737
• There is no possible support for previous server versions

TODO

• replace recursion with iteration
• start by a folder name (InitialFolderTree)
• replace system cURL with Mojo::UserAgent
• implement login instead of storing auth session cookie (expires in 15 minutes)
