OpenMAX (Open Media Acceleration), often shortened as "OMX", is a non-proprietary and royalty-free cross-platform set of C-language programming interfaces. It provides abstractions for routines that are especially useful for processing of audio, video, and still images.
In latest version of Adobe Premiere Elements 7 and Premiere Pro CS4 (both shipped in 2008), both source-video and video-export (to Blu-ray Disc) support H.264. Apple integrated H.264 support into Mac OS X v10.4 "Tiger" and QuickTime 7. The encoder conforms to Main Profile and the decoder supports Constrained Baseline and most of Main Profile. [1]
IndirectSound is a freeware library that emulates DirectSound 3D using XAudio2, without using hardware acceleration. [16] DSOAL is an open source library that emulates DirectSound 3D and EAX using OpenAL. Either a hardware-accelerated OpenAL implementation or OpenAL Soft (which provides HRTF) can be used. [17]
MPlayer is a free and open-source media player software application. It is available for Linux, OS X and Microsoft Windows.Versions for OS/2, Syllable, AmigaOS, MorphOS and AROS Research Operating System are also available.
An example of vainfo output, showing supported video codecs for VA-API acceleration. The main motivation for VA-API is to enable hardware-accelerated video decode at various entry-points (VLD, IDCT, motion compensation, deblocking [5]) for the prevailing coding standards today (MPEG-2, MPEG-4 ASP/H.263, MPEG-4 AVC/H.264, H.265/HEVC, and VC-1/WMV3).
