OpenNOW PS5 - Prototype

OpenNOW PS5 0.0.7

This prerelease adds audio format selection, multichannel Opus decoding and adaptive audio buffering. Tag 0.0.7 maps to native content version 00.002.037, title ID PPSA99082.

Changes

• Press R2 in the catalog to select Auto, Stereo, 5.1 or 7.1 before launching.
• Request the selected audio format through CloudMatch; choose the widest valid WebRTC Opus layout actually offered by GFN, with stereo fallback.
• Decode explicit multiopus stream/channel mappings and route family-1 speaker order to the PS5 eight-channel PCM output. Follow negotiated RTP/RED payload IDs.
• Keep 48 kHz audio and request bitrate ceilings of 256 kb/s stereo, 384 kb/s 5.1 and 510 kb/s 7.1. The server determines the actual bitrate.
• Adapt the jitter reserve from 20 to 40 ms after starvation, account for packet duration at startup, bound queue excess and preserve the newest samples.
• Retain RED recovery, add in-band FEC attempts with PLC fallback, and restart the audio epoch on large or invalid timestamp gaps.
• Recover from seats that initially send valid stereo despite describing surround.
• Report negotiated/requested channels, primary codec bitrate, queue depth, dropped frames, output errors and recovery counters in private diagnostics.
• Remove the fixed stereo label from video output information.

Validation and limitations

Host regressions passed with ASan/UBSan, including allocation, malformed offer fallback, channel placement, dynamic RED payloads, queue overflow and re-priming, and sustained 20 ms packets with 256-frame output grains. The synthetic catalog preview was visually checked. The native GPU package built on the Linux VPS and passed its import audit.
