Media File Tools

Introduction

VASTreaming provides a set of ready-to-use utilities for common media file operations—sequencing, splicing, mixing, and extraction. Call them directly from your code to build automated media processing pipelines without external tools.

Playlist

Present multiple files as a single seamless source, or extract a specific time range from a file. The playlist engine handles gapless transitions and works as a drop-in source for any VASTreaming streaming component.

MP4 Utilities

AudioMixer—merge audio tracks from two or more MP4 files into a single output track. Video is copied from the primary source file.

Concatenator—splice multiple MP4 files into one continuous file. Also works as a trimmer: pass a single file with start and end timestamps to cut a precise segment.

ImageExtractor—extract a frame from any position in an MP4 file and save it as a JPEG image. Ideal for thumbnail generation and preview workflows.

VideoMixer—overlay images onto an MP4 video, including animated formats such as GIF. Use it for watermarks, lower thirds, and branded content.

Platforms

Available for all major platforms:

• C# / .NET: .NET 6/7/8/9/10+ (cross-platform), .NET Framework 4.5+
