What is the best way to handle local assets in WPF?

Use Pack URIs (e.g., 'pack://application:,,,/Images/icon.png') to correctly reference resources embedded in your application assembly.

How do I prevent memory leaks when loading many images in WPF?

Use the DecodePixelWidth property to resize images at the source and call the Freeze() method on BitmapImage objects to improve performance and allow cross-thread access.

Does MediaElement support MP3 and MP4 formats?

Yes, MediaElement uses Windows Media Player underlying technology and supports common formats like MP3 for audio and MP4 (H.264) for video.

When should I use SoundPlayer instead of MediaElement?

Use SoundPlayer for simple, low-latency playback of WAV files, such as UI clicks or notification sounds. Use MediaElement for complex media that requires seeking, volume control, or multiple formats.

Design Tools

Integrates high-performance multimedia content including images, video, and audio into WPF applications.

About

This skill provides comprehensive guidance for implementing multimedia features in WPF applications, focusing on both functionality and performance. It covers advanced image handling using the Image control, including memory-efficient thumbnail generation and cross-thread access via freezing. Additionally, it offers implementation patterns for the MediaElement control to build custom video players with full playback controls, as well as lightweight audio integration techniques using SoundPlayer. This is essential for developers building media galleries, multimedia UIs, or any .NET desktop application requiring rich asset display.
