[1] [2] It is intended for low power and embedded system devices (including smartphones, game consoles, digital media players, and set-top boxes) that need to efficiently process large amounts of multimedia data in predictable ways, such as video codecs, graphics libraries, and other functions for video, image, audio, voice and speech.
It enables and provides remote access to hardware acceleration for audio and video decoding on the IVA-HD in OMAP4-based platforms via a syslink/rcm shim layer accessing the OMAP's Codec Engine API codec interface on the co-processor (Ducati/M3) from the host under Linux without needing OpenMAX.
Video Decode Acceleration Framework is Apple Inc.'s API for hardware-accelerated decoding of H.264 on Mac OS X; VideoToolbox is an API from Apple Inc. for hardware-accelerated decoding on Apple TV and Mac OS X. [39] OpenMAX IL (Open Media Acceleration Integration Layer) - a royalty-free cross-platform media abstraction API from the Khronos Group
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).
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]
Rockbox is a free and open-source software replacement for the OEM firmware in various forms of digital audio players (DAPs) with an original kernel. [2] [3] It offers an alternative to the player's operating system, in many cases without removing the original firmware, which provides a plug-in architecture for adding various enhancements and functions.
LDAC is an alternative to Bluetooth SIG's SBC codec. Its main competitors are Huawei's L2HC, Qualcomm's aptX-HD/aptX Adaptive and the HWA Union/Savitech's LHDC. [1]LDAC utilizes a type of lossy compression [2] [3] by employing a hybrid coding scheme based on the modified discrete cosine transform [4] and Huffman coding [5] to provide more efficient data compression.
This codec is used in Sony Hi-MD Walkman devices (e.g., "Hi-LP and Hi-SP"), Network Walkman players, Memory Stick players, VAIO Pocket, PS3 and PSP console, and ATRAC CD players. It is a hybrid subband/MDCT codec based on a 16 channel QMF followed by a 128-point MDCT. Prior to MDCT coding, Generalized Harmonic Analysis (GHA) is used to extract ...
