1. Improved H265 RTP packetization for stricter decoders and better mobile compatibility (including and tested on DS-7632NXI-K2 <-> Hik-Connect iOS).
2. Improved ONVIF audio request compatibility for NVR clients (more stable behavior when audio is not enabled on ITVDesk).
3. Improved Combined Channel performance and visual quality by applying per-input scaling/crop parameters
(each combined input can now use its own scaling settings).
4. Main stream default FPS policy refined by source type for better stability and resource usage
(e.g. desktop-like sources vs external/file sources).
5. ONVIF audio advertising is now synchronized with real stream profile state.
If a profile has no audio, the device reports this correctly to NVR clients, reducing connection errors.
6. Added a dedicated profile setting to control which profiles are exposed to NVR auto-discovery.
Typical use: show Main/Sub, hide Third/P2P.
7. Added live client status in the UI channel list:
`[LIVE]/[IDLE]` markers, connected client count, and last activity tooltip per stream.
8. Resolution profile updates:
- Main stream now supports up to 8MP (`3840x2160`) in stream configuration UI.
- Substream now supports up to `1280x720` (720p) for modern NVR/mobile usage.
9. Updated substream defaults for better quality/performance balance:
- Default substream: `1280x720`
- Automatic fallback to `640x480` on lower source resolutions
- Default substream FPS: `8`
- Default substream bitrate: `768 kbps` (720p) / `384 kbps` (fallback)
10. General ONVIF + RTSP stability improvements for faster and more reliable NVR/VMS interoperability.
