ppobs v32.1.2-rc002
This version includes enhanced WHIP/P2P streaming, HEVC/H264 multi-track simultaneous broadcast, SRT simultaneous broadcast, optimized live streaming settings, improved image quality processing capabilities, and stability fixes.
WHIP / P2P Streaming
- Added WHIP HEVC + H264 multi-track streaming
- H264 and HEVC use separate WHIP sessions
- Each session carries audio separately
- Supports multi-layer Simulcast for H264/HEVC
- Automatically matches the corresponding vendor's H264/HEVC encoder
- Provides explicit prompts when the HEVC encoder is unavailable
- Added WHIP P2P NAT detection
- Detects the publisher's NAT type before streaming
- Persistentizes device ID
- Automatically downgrades to Edge-only when NAT detection fails, without blocking streaming
- Added PPCenter STUN service deployment and configuration
- Enhanced P2P WebSocket signaling security
- Forces remote signaling to use
wss:// ws://only allows localhost/loopback- Fixed IPv6 loopback address handling
- Fixed WHIP connection establishment, reconnection, and termination processes
- Faster disconnection recovery
- Added reconnect watchdog
- Limit reconnection frequency to avoid duplicate reconnection threads
- Fixed data transmission race condition when connection is closed
- Fixed residual reconnection after degrade WebSocket stops
- Fixed issue where the encoder remained active after WHIP output failure
- Fixed issue where WHIP output was stuck at 0 bitrate
- Support for
{ppcenter_appid}expansion - WHIP endpoint supports App ID placeholders
- Custom SRT URL's
streamidalso supports App ID placeholders
Simulcast / SRT
- Added single SRT connection to carry multiple Simulcast streams
- Each video encoder outputs an independent H264 elementary stream
- Support for routing video packets by
track_idx - Each layer independently waits for a keyframe before starting transmission
- Preserves the high-to-low Simulcast hierarchy order
- Creates independent FFmpeg
AVStreamand encoding state for each layer - SRT Simulcast is limited to a maximum of 4 layers.
- WHIP Simulcast is also limited to a maximum of 4 layers.
- SRT multi-channel video requires all video encoders to be H.264.
- Fixed compatibility issues with the first H.264 Access Unit of the hardware encoder.
- Supports valid Annex-B leading zeros.
- Supports 4-byte AVCC to Annex-B conversion.
- Correctly cleans up FFmpeg/MPEG-TS state when initialization fails.
- Custom services no longer display inapplicable independent "Multitrack Video Settings".
- Retains the unified "Simultaneous Playback Configuration" entry for custom services and WHIP.
Push Streaming Limitations
WHIP push streaming has added hard limits, applicable to all startup methods and reconnection paths:
- Maximum landscape resolution:
3840x2160 - Maximum portrait resolution:
2160x3840 - Maximum FPS:
60 - Maximum video bitrate:
10000 Kbps - H264, HEVC, and all Simulcast layers are validated separately.
- Output stops and a clear error is logged when limits are exceeded.
- Settings interface provides advance warning of resolution and FPS exceeding limits.
Live Streaming Settings
- Unified configuration items for custom services and WHIP:
- Endpoint
- Simultaneous Broadcast
- Authentication Center
- Interval Live Streaming Configuration
- Custom and WHIP endpoints are remembered separately.
- Endpoint addresses will not be used interchangeably when switching between the two services.
- Authentication center configuration is also displayed for custom services.
Custom service authentication center fields are saved to the corresponding service settings.
Custom services retain the user-selected audio encoder. - No longer automatically switching or hiding encoders such as Opus based on protocol recommendations.
- Simultaneous broadcast encoders are uniformly limited to 4 layers.
Image Quality and Video Processing
- Added Clarity filter
- Added Temporal Denoise filter
- Added basic Beauty filter
- Added face beautification/stylization capabilities
- Added ROI-Related Capabilities
- Manual ROI selection
- Decoupling ROI from WHIP service settings
- Moving ROI settings to the video settings page
- Adding live streaming quality score
- Calculating video quality score and PSNR
- Supporting quality degradation alerts
- Supporting quality score preview overlays
- Adjusting quality processing defaults and UI text
- Enhancing QSV/hardware encoder bitrate cap handling
Network and Clock
- Adding Windows network adapter type recognition
- Ethernet
- Wi-Fi
- Cellular
- Other/Unknown
- Adding the following to RTMP and WHIP logs:
- Network interface card description
- Network interface card type
- Uplink and downlink speeds
- Adding active network adapter logs at startup
- Improved NTP clock calibration
- Anchoring the calibrated clock to the system wall time
- Improved streaming timestamp stability
