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.
