Symbian, the consortium that develops the mobile operating system of the same name, plans to add in APIs for multimedia applications, a bearer mobility capability and technology for greater code density on ARM processors to the OS over the next 18 months. Two of the multimedia APIs come from the Khronos Group, OpenSL ES and OpenMAX IL, said Andy Moran, head of enterprise at the London-based company. Symbian intends to implement OpenGL ES, another Khronos Group API for full-function 2D and 3D graphics, enabling mobile TV, videoclips on a phone and so on.
Khronos Group Releases OpenMAX AL 1.0 and OpenSL ES 1.0 Specifications for Embedded Media and Audio Processing
The Khronos™ Group has publicly released provisional versions of the OpenMAX™ AL 1.0 and OpenSL ES™ 1.0 specifications to enable widespread developer feedback and rapid industry implementation of these new standards that are designed to bring portable, state-of-the-art audio, video and image acceleration to mobile handsets and embedded devices. Both specifications are expected to be finalized by mid-2008. Read the press release.
Mentor Graphics Corporation today announced the launch of the Inflexion Platform ™ Multimedia Feature Pack for Nucleus® OS, a new paradigm for manufacturers of mass market consumer electronic devices to bring advanced audio and video capabilities to their products. To ensure maximum interoperability, Inflexion Platform Multimedia Feature Pack implements the new OpenMAX™ industry standard API. This means that any OpenMAX-compliant multimedia component -- including audio and video codecs -- can be integrated with minimal effort, including those which take advantage of accelerated graphics hardware. “OpenMAX has wide industry support, enabling the rapid and flexible deployment of streaming media acceleration on a wide range of silicon platforms and operating systems,” commented Neil Trevett, president of the Khronos Group. “Mentor Graphics’ announcement today is truly significant as it enables embedded developers to take advantage of the full power of OpenMAX across the wide range of embedded platforms that use Nucleus OS.”
ARM, the microprocessor intellectual property (IP) company, specialising in RISC processors and system-on-a-chip (SoC), has made available OpenMAX DL API libraries for the decoding of AAC audio format and H.264 video format. These libraries are optimised to take advantage of the SIMD instruction set found in ARM Cortex-A8 and ARM11 series processors. ARM also announced its goal to add more optimized OpenMAX DL functions for MP3, JPEG and MPEG-4 decode.
The Khronos Group today posted slides from several of the Birds of a Feather sessions that were held at the 2007 Siggraph in San Diego. Included in the slide collections are OpenGL, OpenGL ES, OpenKODE, OpenVG and OpenMAX. There is also a collection for the Japan BOF. You can view the slides on the Khronos Groups Developer Library in PDF format.
Khronos is happy to announce a very well rounded Birds of a Feather (BOF) schedule for SIGGRAPH’s 34th international conference and exhibition on computer graphics and interactive techniques. Running August 7th and August 8th at the San Diego Convention Center, these informal get-togethers are filled with presentations, discussions, and demonstrations for people who share interests, goals, technologies, environments, or backgrounds in OpenGL, OpenGL ES, OpenKODE, COLLADA, OpenVG, OpenMAX and much more.
The presentations from Emerging Technology Forums @ CTIA Wireless are now available as PDFs. Presentations cover Benchmarking, Mobile Media APIs, Mobile Media Trends and OpenMAX.
The newly ratified and released OpenMAX IL 1.1 defines enhanced media component interfaces to enable the rapid integration of media acceleration into streaming media frameworks on embedded devices. OpenMAX IL 1.1 adds significant functionality to OpenMAX 1.0 including standardized components, interfaces and controls; enhanced video and camera controls; extended color formats; and integration with EGL to seamlessly integrate with OpenGL ES and OpenVG. The OpenMAX IL 1.1 Adopter's Program has also been launched. See press release.
The presentations from the full day Khronos Media Acceleration Forum in Cambridge UK are now online. These presentations include OpenKODE, a non-technical introduction to OpenGL ES, hardware-accelerated OpenVG, OpenSL ES overview, a technical overview of OpenGL ES 1.1, a technical overview of OpenMAX DL, IL and AL, how shader programmability with OpenGL ES 2.0 can boost overall system level performance, and high-performance 3D graphics coding for handheld devices.
Episode #4 in the Khronos Mobile Media Developer podcast series focuses on OpenMAX DL - a standard to enable rapid porting of codecs to new platforms. OpenMAX DL (Development Layer) APIs contains a comprehensive set of audio, video and imaging functions that can be optimized by platform developers for new CPUs, hardware engines, and DSPs. Developers can then use the APIs to create portable accelerated codec functionality such as MPEG-4, H.264, MP3, AAC and JPEG. They can port the codec to a new platform simply by getting the appropriate platform library.
