Aurora 1.2.3

5.1 audio dropouts are fixed, Experimental/Host now show the settings that were previously unreachable, and there is a new V-Sync attempt that actually talks to NDL.

Audio — 5.1 dropouts (#66)

5.1 could go silent for a few seconds at 4K/high bitrate. The TV's Opus surround transcode was running on the RTP receive thread (CAPABILITY_DIRECT_SUBMIT), so a slow transcode starved the socket.

• Audio on webOS no longer uses direct submit — Limelight's decoder thread absorbs the transcode.
• The NDL 5.1 Opus transcode runs outside the NDL lock, at encoder complexity 0.
• Experimental → Decode 5.1 in the client (PCM) skips the TV transcode entirely if it still cuts out.

Frame pacing — another V-Sync attempt

Every previous pacing scheme (PTS grid, host PTS, presentation offset, panel-phase, holding Feed) changed when Aurora submits. NDL was still given PTS = now, so its render buffer stayed empty and it could not vsync.

Experimental → Frame pacing now places the PTS N frames in the future so the TV queues frames and releases them on its own V-Sync. Start with V-Sync, 3 frames (~25 ms extra at 120 fps). Turn Show logs on: after a session you should see Render pacing: … queue avg … starved ….

• queue avg near target, starved near 0% → the TV is holding frames. If pans still judder, presentation is not the remaining problem.
• queue avg ~0, starved ~100% → NDL ignores a future PTS. V-Sync is not possible through NDL.

Settings that were invisible

The compact Settings UI only instantiates Stream / Input / Host / Experimental. Video and Audio panes compiled but were never shown.

Now in Experimental:

• Frame pacing (V-Sync via render buffer)
• Full range YUV (SDR)
• Periodic decoder refresh (HEVC)
• Decode 5.1 in the client (PCM)
• Adaptive bitrate + mode

Now in Host:

• Quit the game when the stream ends
• Resume a running game automatically

Notes

• video.pane.c / audio.pane.c were deleted so this trap cannot repeat.
• The old Feed-hold “V-Sync gate” was removed; it did not work.
• Config is preserved across TV updates (moonlight.ini restore).
