  • MPEG-TS files multiplexed with packets size greater than 188 bytes now can be opened correctly
  • Ability to open HEVC streams without IDR/CRA/BLA NAL units

26 April 2017 3.7.1704.26

Features:

  • High Dynamic Range (HDR) Detection and Analysis. Frame-by-frame parsing and interpretation of SEI units into discrete Frame Information.
  • Hypothetic Reference Decoder (HRD) Buffer Flow: Instant insights into buffer occupancy – available from the interface and through CLI reports.
  • Comprehensive File Info in a Single Source, including profile, level, chroma subsampling, bit depth, resolution, aspect ratio, bitrate, frame rate, HDR information, compression efficiency, and GOP length statistics.
  • Bitrate Histogram. Bitrate peak values update every second in the course of consecutive frame reading

16 March 2016 3.1.1603.16

Features:

  • Support of MP4 (MPEG-4 Part 12) file format for HEVC/H.265 video streams
  • Increased speed with translucent overlays of the image of encoded file (PU, TU, QP, Bits, RefIdx, PSNR) for high-resolution files: the mapping, scaling, responds to mouse movement
  • Added data in the generated report in the console mode: average PSNR and SSIM for the whole file, file size, duration, bitrate

Fixes:

  • PDF specification file was not displayed
  • Extra blank lines in the report file were removed
  • Fixed the crash on files with the data of HRD model if there are some pic_timing SEI missed
  • Fixed a problem with opening a HEVC file if it does not begin with a key frame, but with the frame with a large value of the Picture Order Count
  • Displaying of an error message when opening an unsupported file
  • The current marker was not updated sometimes
  • Wrong preview picture on frames with dimensions not multiple of 4
