Video SDK for Encoding, Decoding and Transcoding¶
The AVBlocks Video SDK is a cross-platform library for building video encoding, decoding and transcoding into your own applications. It is available for C++, .NET (C#, VB, F#) and Python, and runs on Windows, macOS and Linux.
Unlike real-time streaming SDKs, AVBlocks is a file-based video SDK: you give it a source file or stream, set an output format and codec, and it produces a finished media file — ideal for transcoding services, batch converters, media servers and post-production tools.
What you can build with the Video SDK¶
Video transcoding services — convert between MP4, MPEG-TS, WebM, AVI and more.
Batch video converters — process large libraries with a consistent API.
Encoding pipelines — encode raw frames to H.264, H.265/HEVC, VP9 or MPEG-2.
Decoding / playback tools — decode H.264, HEVC, VP9, MPEG-2, VC-1 and others.
Video processing — resize, crop, de-interlace, overlay images and change frame rate or bitrate.
