SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

You need a reliable way to integrate VisioForge Video Edit SDK X into an Avalonia app that renders and joins media on Windows, Linux, and macOS without breaking due to per-OS native dependencies, initialization order, or missing licensing data.

Core Features & Use Cases

  • Cross-platform editor integration: Wire up VideoEditCoreX with an Avalonia VideoView, a timeline-style input list, and a single configurable output format.
  • Per-OS packaging & runtime dependencies: Add the correct Windows/macOS NuGet native runtime redists via OS-conditional csproj groups, while relying on system GStreamer on Linux.
  • Common failure avoidance: Prevent typical issues such as DllNotFoundException / missing elements, Linux “element not found” errors from absent GStreamer plugins, and trial-period expiry due to missing license certificate loading.
  • UI-safe lifecycle and event handling: Marshal OnProgress/OnStop updates onto the Avalonia UI thread and ensure shutdown uses Stop() → Dispose() → VisioForgeX.DestroySDK().

Quick Start

Copy references/Sample.csproj, references/Program.cs, references/App.axaml + references/App.axaml.cs, and references/MainWindow.axaml + references/MainWindow.axaml.cs into a new Avalonia project, then build on your target OS and use the Start/Stop buttons to join selected clips into the chosen output format.

Frequently Asked Questions about video-edit-sdk-x-avalonia

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build a cross-platform non-linear video editor UI in Avalonia?▼

To build a cross-platform non-linear video editor UI in Avalonia, you integrate VideoEditCoreX with a VideoView component and a timeline-style input list to concatenate audio, video, and image clips across Windows, Linux, and macOS.

What causes DllNotFoundException or missing element errors when joining media on Linux?▼

DllNotFoundException and missing element errors during media joining on Linux occur when system GStreamer plugins are absent. You must ensure the correct OS-specific native runtime dependencies are packaged and rely on the system GStreamer installation for Linux.

How do I manage the lifecycle and UI thread events for a cross-platform video editor?▼

To manage the lifecycle and UI thread events for a cross-platform video editor, marshal OnProgress and OnStop updates onto the Avalonia UI thread, and execute Stop(), Dispose(), then DestroySDK() during shutdown to prevent failures.

How do I render concatenated video clips to multiple output formats from one codebase?▼

You render concatenated video clips to multiple output formats from one codebase by configuring a single output container and codec target within the VideoEditCoreX timeline before calling the Start method.

Do I need to load a license certificate before starting video rendering in Avalonia?▼

Yes, you need to load a license certificate. You must call SetLicenseCertificateAsync before calling Start to prevent trial-period expiry issues and ensure uninterrupted SDK video rendering functionality.
