Black screen in the Parsec web client

[spaztron64]

Describe the bug When trying to remotely control a Parsec host through the web client at https://web.parsec.app , the user is met with a black screen instead of a compressed video stream of the host. The metrics at the top of the screen report "H.264: N/A". Audio does come through.

Checking the Console shows the following error: parsec.js:32 Uncaught DOMException: Failed to execute 'configure' on 'VideoDecoder': Cannot call 'decode' on a closed codec. at RTCDataChannel. (https://web.parsec.app/lib3/parsec.js:32:393)

To Reproduce Steps to reproduce the behavior:

1. Go to https://web.parsec.app and log into your Parsec account
2. Click on the connect button underneath one of your available hosts
3. Pick the "Web Browser" option
4. Be met with a black screen

Expected behavior The user should be able to see the screen of the remote host and operate it. In my case, the host is a Windows Server 2022 machine.

Desktop (please complete the following information):

• OS: Windows Server 2008 R2 x64 SP1, confirmed to be happening on Windows 7 x64 SP1 as well
• Supermium 122.0.6261.152, 64-bit

The same on Ubuntu / Chrome

Same happens on native Chrome, so more likely a Parsec error.
