Replay Source crashes OBS and fails to save replays on macOS (Apple Silicon, OBS 31.x)

[jeanribas]

Environment:

• macOS (Apple Silicon: M1/M2/M3)
• OBS Studio 31.x
• Replay Source plugin (version 1.8.1)
• Replay directory: /Users/jeanribas/OBS/GRAVACOES/Replay Source/Replay1
• Filename format: %CCYY-%MM-%DD %hh.%mm.%ss

Describe the bug (Unexpected behavior):

1. Pressing "Save Replay" logs success in OBS, but no file appears in the target folder (forum reports) :contentReference[oaicite:1]{index=1}.
2. Stopping recording or closing OBS hangs at "stopping recording..." and needs force quit (common on Apple Silicon + similar plugins) :contentReference[oaicite:2]{index=2}.
3. High memory/CPU usage during replay; several users report heavy resource consumption and crashes in OBS 31.x setups :contentReference[oaicite:3]{index=3}.

Steps to Reproduce:

1. Install Replay Source on macOS w/ OBS 31.x.
2. Add Replay Filter + Source to scene; configure duration (e.g., 5s), hotkeys.
3. Trigger "Load Replay" → loads correctly.
4. Trigger "Save Replay" → logs indicate success, no file.
5. Exit OBS → application hangs indefinitely.

Expected behavior:

• Replay files are saved correctly in the folder with configured filename.
• OBS exits normally (no hang or force quit).
• Memory usage remains moderate (< 1 GB for 5 s buffer).

Logs & Crash Reports:

• OBS logs (Help → Log Files → Upload Last Log)
• macOS crash report from ~/Library/Logs/DiagnosticReports/obs_*.crash

Suggested fixes:

• Ensure saveReplay() always writes an output file to the specified directory.
• Address memory leak and buffer cleanup to reduce RAM usage.
• Fix hang in stopRecording() or plugin shutdown path—ensure OBS can quit cleanly.

Additional context:

• Many forum reports recommend native OBS Replay Buffer for stability on Apple Silicon, and mention that obs-instant-replay is a better-functioning alternative :contentReference[oaicite:4]{index=4}.
• Users on OBS forums and Reddit have repeatedly noted similar issues with no fix in recent updates :contentReference[oaicite:5]{index=5}.
