Detailed Description

Intel® Media Server Studio 2017 R3 - Video Quality Caliper (VQC) is a graphical utility for objective and visual quality inspection of encoded or uncompressed videos. It is able to work with elementary AVC, HEVC and VP9 streams decoding them on-the-fly using embedded Intel® Media SDK software decoders. It also supports several uncompressed YUV video formats making it useful for the new codec development. In order to measure objective visual quality, fast and accurate implementations of the mainstream PSNR/SSIM metrics (VQM), together with some experimental ones, are provided. Selected VQMs are visualized as a per-frame graph in the main application window together with frame preview and RD-chart toggle. Additionally, videos can be inspected per-frame with help of a details window that supports rapid switching between three streams, arbitrary zoom, color channel selection and difference highlighting.

VQC is using Qt library and D3JS visualization library, VP8/VP9 decoder implementation is based on reference WebM libvpx library.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
