Add AV1 Hardware Encoding + Decoding to Your App

Add AV1 Hardware Encoding + Decoding to Your App

November 13, 2023

MPlatform SDK V2.8 adds support for NVIDIA hardware encoding / decoding, allowing you to work with high-resolution #AV1 streams.

The MPlatform SDK is a professional multimedia software development kit that supports native C#, VB.NET, VB6, Visual C++, and Embarcadero Delphi, allowing you to create broadcast automation, ingest, and video mixing applications.

MPlatform SDK v2.8 adds support for AV1 NVIDIA hardware encoding and decoding. AV1 is a next-generation video codec that offers superior compression efficiency and image quality compared to older codecs like H.264 and HEVC. NVIDIA GPU hardware encoding is much faster than CPU-based encoding. Hardware decoding allows users to play back AV1 video with lower CPU usage and power consumption. The addition of hardware encoding/decoding to the MPlatform SDK makes working with high-resolution AV1 streams more efficient and practical.
