What's New in Intel® Media SDK 2017 for Windows*

Innovative Features Improve Visual Quality in Video Apps 

Media application developers, gain a competitive edge: new release Intel Media SDK 2017 for Windows* delivers HEVC and AVC visual quality, bitrate and latency control improvements.

The new release improves HEVC encode bitrate control by adding an ability to set maximum frame size. Previously available for AVC only, this feature now allows developers using HEVC in streaming applications to adapt frame size to network conditions. It helps to achieve lower latency, reduce the number of lost packets and as a result, get higher visual quality and a better viewer experience.

Intel Media SDK 2017 also provides AVC encode features improving bitrate control in applications that require low latency (e.g. game streaming), ensuring stream robustness to network connection issues and delivering higher visual quality for OTT broadcasting. Key features are:

  • Slice based and dynamic intra refresh
  • Low delay and sliding window bitrate controls
  • Ability to set maximum size for I- and P-frames
  • Explicit weighted prediction for P- and B-frames
  • Fade detection
  • RGB input control via video signal info
  • Forced intra-based region of interest
AVC Encode Adaptive QVBR Low Delay in Media SDK 2017 for Windows*
Significant advantages in bitrate accuracy in packet constrained environments

Comparison of Average bitrate accuracy over 10 test stream, each 3600 frames long, showing dramatic improvement under highly constraining bitrate requirements, similar to online gaming.  The left (blue) bar corresponds to average QVBR bitrate control constrained by Max Frame Size; the right (orange) bar corresponds to average bitrate from the new Low Delay BRC mode, likewise constrained by MaxFrameSize.  In both sequences, MaxFrameSize for P-frames is equal to the average frame size; while MaxFrameSize for I frames is set to 3X the P-size.  Error bars represent the maximum and minimum across all sequences. Tests were performed by Intel, and run using Intel® Media SDK 2017 for Windows*, on Windows* 10 64-bit, Intel graphics driver 15.45, Intel ® 6th Generation Core™ i5-6260U Processor, 8 GB DDR3-1600, on an Intel NUC model NUC6i5SYH.  Tests of 10 standard 1080p60 sequences from https://media.xiph.org/video/derf/  Gaming section, at 16, 20, and 24 mbps. See also footnotes below.


New features are enabled for the latest Intel platforms:

  • 6th and 7th generation Intel® Core™ processors
  • Intel® Atom®, Celeron®, and Pentium® processors formerly known as Apollo Lake
