Media and video application developers can tune for even more brilliant visual quality and fast performance with new HEVC technology inside the just released Intel® Media Server Studio Professional Edition (2017 R3). In this new edition, key analysis tools' enhancements provide better and deeper data insights on application performance characteristics so devs can save time targeting and fixing optimization areas. The Intel Media Server Professional Edition includes easy-to-use video encoding and decoding APIs, and visual quality and performance analysis tools that help media applications to deliver higher resolutions and frame rates.
For this release, Intel improved the visual quality of its HEVC encoder and decoder. Developers can optimize for subjective video quality gains of 10% by using Intel’s HEVC encoder combined with Intel® Processor Graphics (GPU). Developers can also optimize for subjective quality gains of 5% by using the software-only HEVC encoder. Other feature enhancements include:
- Improved compression efficiency for frequent Key Frames when using TU 1 / 2 encoding.
- Support for MaxFrameSize for constrained variable bitrate encoding, which results in better quality streaming.
- Advanced user-defined bitrate control. The software and GPU-accelerated HEVC encoders expose distortion metrics that can be used in concert with recently introduced external bitrate controls to support customized rate control for demanding customers.

Optimize Performance and More with Super Component Tools Inside
Intel® VTune™ Amplifier
The Intel Media Server Studio Professional Edition includes several other tools that help developers understand their code and take advantage of the advanced Intel on-chip GPU. One of the more powerful analysis tools is Intel® VTune™ Amplifier. This tool allows for GPU in-kernel profiling, which helps developers quickly find memory latency of inefficient kernel algorithms. This analysis tool also provides a GPU Hotspots Summary view, which includes histograms of Packet Queue Depth and Packet Duration for analyzing DMA packet execution.
With Intel® VTune™ Amplifier, developers can also:
- Detect GPU stalled/idle issues to improve application performance.
- Find GPU hotspots for determining compute bound tasks hindered by GPU L3 bandwidth or DRAM bandwidth.
Intel® SDK for OpenCL™ Applications
Intel® SDK for OpenCL™ Applications (2017 version) is also included in this release of Intel Media Server Studio Professional Edition. This SDK adds OpenCL support for additional operating systems and platforms. It's fully compatible in Ubuntu* 16.04 with the latest OpenCL™ 2.0 CPU/GPU driver pages for Linux* OS (SRB5).
