PRO Capabilities

Decode and Rendering Enhancements

• WASM multi-threaded decoding for H.264/H.265 at 1080P+ workloads — effectively utilizes multi-core processors for smooth playback.
• WASM SIMD and SIMD + multi-thread acceleration paths for maximum decode performance.
• MPEG4 software decode support (PRO-exclusive).
• Expanded rendering modes: canvas / webgl / webgpu / video element combinations, configurable via useCanvasRender and useWebGPU.
• Long-running foreground/background anti-latency accumulation strategies with configurable videoBuffer and videoBufferDelay thresholds.
• Hardware decoding with worker-based demuxing via demuxUseWorker option.

Protocol and Stream Coverage

• Extended live protocols: HLS (including H.265), fMP4, TS/PS, WebTransport, and broad WebRTC variants (m7s, ZLM, SRS, Alibaba Cloud, and custom servers).
• Encrypted stream support: m7s private crypto, SM4 (national standard), XOR encryption, and HLS AES-128 CBC scenarios.
• Naked stream playback for raw H.264/H.265 without container formats.
• VOD support for MP4 and HLS (TS/MP4), including playback control enhancements.
• Playback stream workflows for GB28181, GA/T 1078, and special replay modes with 24-hour timeline and fixed-duration timeline support.
• Configurable playback rates: dynamic (from stream) or fixed (local setting) with I-frame only decoding at 2x/4x/8x speeds.

Try it → See PRO — Encryption and PRO — Playback demo sections.

Enterprise UI and Control Modules

• Advanced PTZ panel with 8-direction control, zoom/focus/aperture/iris operations, cruise (patrol), defog, and wiper controls — supports GB28181 encoding output.
• Custom control buttons and customizable control-bar HTML content via controlHtml and operateBtns configuration.
• Resolution switching UX with configurable quality levels (qualityConfig).
• Digital zoom (electronic magnification) module with programmable zoom rect control.
• N×N multi-view layouts: 2×2, 3×3, 4×4 regular grids and irregular split modes with per-window drag-sort, selection, and partial fullscreen interaction.
• Display mode controls: mirror (horizontal/vertical), rotation (0°/90°/180°/270°), and aspect ratio (default/fill/stretch, custom ratios).
• Bottom bar auto-hide, custom context menus, and performance panel toggle.

Try it → See PRO — Multi-screen, PRO — Advanced Features, and PRO — UI & Controls demo sections.

Recording, Watermarking, and Security

• Recording formats: WebM (audio+video), MP4 (video), FLV (audio+video) — scenario-dependent with extended module paths.
• Watermark modes:
  • Local watermark — positioned overlay with configurable text, opacity, and size.
  • Fullscreen watermark — tiled text across the entire viewport.
  • Dynamic watermark — moving overlay to prevent screen capture.
  • Ghost watermark — invisible watermark for forensic tracing.
• Screenshot watermark and hidden watermark options for compliance workflows.
• Security-oriented controls for enterprise playback governance workflows.

Try it → See the Dynamic watermark and Video recording demos under PRO — Advanced Features.

Network Resilience and Lifecycle

• Auto-reconnect on timeout, disconnection, and playback errors — configurable retry count (including unlimited), delay intervals, and no-black-screen options.
• Separate timeout handling for loading phase and playback phase with independent retry policies.
• WebSocket 1006 error and stream end/error internal retry with configurable delay.
• Decoder error auto-fallback to WASM mode via decoderErrorAutoWasm.
• Show last frame during replay transitions for seamless user experience.
• Video carousel (looping through multiple streams) with configurable interval and last-frame display.
• Page visibility lifecycle management: auto-pause on tab hide with configurable delay.

Try it → See Error recovery, Video carousel, and Page visibility demos.

AI and Operational Tooling

• AI modules: face detection, object recognition, occlusion/screen anomaly checks.
• Crash and exception telemetry hooks (crashLog event) for support and diagnosis.
• SEI metadata extraction from multiple stream containers via videoSEI event.
• Custom overlay rendering: draw text, rectangles, and combined overlays on the video canvas for annotation and detection visualization.
• Weak-network handling strategies with low-FPS replay triggers.
• Visibility/focus lifecycle hooks and advanced runtime monitoring support.

Try it → See SEI metadata and Custom overlay demos under PRO — Advanced Features.

Audio and Communication

• Audio-only player (jessibuca-pro-audio-player.js) for audio-only streaming scenarios.
• Voice communication (talk) via jessibuca-pro-talk.js:
  • Single-channel audio capture and WebSocket transmission.
  • G.711 A-law/U-law encoding at 8kHz, 16-bit precision.
  • RTP protocol encapsulation support with GB standard TCP/UDP formats.
  • Configurable sample rate, precision, and container format (raw or RTP).
• Multiple audio engine options: script (default), worklet, and active (mobile browser compatible).

Try it → See the PRO — Audio & Talk demo section.

File Structure

The PRO distribution includes the following key files:

Note: Only include one of jessibuca-pro.js or jessibuca-pro-multi.js, not both. TypeScript definitions are available in the d.ts/ folder.
