Record the last 30 seconds from the session menu (NVIDIA Instant Replay / Highlights)

[lippdev]

Idea

The session menu (Select + Y) already shows Record last 30 s as Soon. Make it work: one press saves the last 30 seconds of gameplay, without leaving the game. Ideally also a controller shortcut, and a toast in the corner when the clip is saved.

NVIDIA first

• Instant Replay (NVIDIA app / GeForce Experience): when it's on, the driver keeps a rolling buffer and Save the last N minutes (default Alt+F10) writes the clip. Console Mode can trigger that shortcut. Needs: detect that the NVIDIA app is installed and Instant Replay is enabled, and read the user's shortcut if they changed it.
• NVIDIA Highlights SDK: made for games to mark moments (a kill, a win) that the NVIDIA overlay turns into clips. A third-party app like ours may not be allowed to request highlights for another process; worth checking the SDK terms and whether it works outside the game's process before relying on it.

Fallbacks for everyone else

• Xbox Game Bar: Record that (Win+Alt+G) when background recording is on. Works on any GPU.
• AMD Adrenalin (ReLive): Instant Replay save (Ctrl+Shift+S by default).
• OBS: replay buffer through obs-websocket (SaveReplayBuffer), for people who already use OBS.

Sketch

• Settings → "Recording": automatic (NVIDIA → AMD → Game Bar) / pick one / off.
• The session menu tile saves the clip, closes the menu and shows Clip saved (or Instant Replay is off with a hint to turn it on).
• The menu closes before the key press, so the clip doesn't show the menu.

Open questions

• Is sending the shortcut reliable while the game has the foreground (it should be, the menu already works there)?
• Can we tell the save actually happened (new file in the capture folder)?
• 👍 this issue and say your GPU and which recorder you use.

Not planned for a specific version yet.
