⏺️ Call recording

[nickvergessen]

Following up on #1232 and some other issues here is the draft of the call recording feature we plan to work on.

📐 Design

Mockups & prototypes

• Top bar is extended to show Add useful information to the top-bar when in a call #6766
  • Headline: Conversation name
  • Subline:
    • Recording icon when the call is being recorded
    • Duration of the call
    • Number of call participants
    • Description of the room
• To start or stop a recording any moderator can use the "…" menu in the topbar next to the Call button
  • Starting and stopping should be logged as a system message
  • It might be necessary to play a sound when recording is started/stopped (to be clarified)
• The recording shall be shared in the chat as a "normal file" but have a special section in the Media tab of the sidebar
• Option to only record audio?

⚙️ Engineering

Requirements

• Recording will be done with a virtual participant
  • Recording will be only speaker view for v1
  • First shared screenshare will be recorded if there is any
• Web UI needs to show the same thing in "Promoted view" that is being recorded (currently not the case when sharing your own screen)
• The recording shall be uploaded to either the/a owner/moderator of the conversation or to a "recording bot" users storage and then shared back into the chat.

Constraints

• Only supported with HPB
