VQ Analyzer v4.1.0 New Features

With the latest version, VQ Analyzer v4.1.0, many new features and improvements have been made to accelerate the video analysis.

  • GUI (Syntax Elements Widget and Stats Widget):
    • Add search box to find syntax element by name
    • Save/restore stat's state on exit/start of application
  • AV1:
    • Improve performance and reduce memory usage
    • Add "Reference Info" panel
    • Add new stats ("Block size by pred": intra/inter; "Partition," "Luma Angle delta by mode," "Chroma Angle delta by mode")
  • HEVC:
    • Improve performance: implement new multithreading scheme
    • Add Reference and Low-delay flags at stats
  • Console:
    • Add new console option for dumping syntax elements statistics ("-syntax_stats" option)
    • Add new console option for extracting sub stream ("-extract", i.e. "-extract gops" - for splitting stream into gops' substreams)
    • Output motion vectors stream's stats

Inspect, Debug, and Improve Encoders

Inspect each step of the encode/decode process visually and numerically. VQ Analyzer can help to debug certain quality and decisional miss in coding pipelines, potentially saving months of man-hours on important video projects. Quickly find and navigate to bitstream and coding mode decision errors and debug broken streams by a click. Conduct side-by-side streams comparison for progress/regression check.

Compliance Validation/Error Reporting

Test for output bitstream spec compliance to ensure output video can be parsed without depending on the error resilience features of specific decoders. Automatable logging can increase testing coverage. Analysis features help root cause issues quickly.


Graphically Analyze Coding Flow, Heat Maps, Motion Vectors, Prediction Processes, and More

These features accelerate development by providing insights on the algorithm choices that produce a bitstream. It can also empower testing/quality assurance with checks for output suitability to quickly assess where all is well and dive deep to root cause issues.


Bitstream Error Detection and Visualization, Bitstream Error Navigation

If your favorite Analyzer just crashed with a stream than open the stream with Vicue Analyzer to understand what is wrong. “Error” button at the bottom left of the window will signal if Analyzer detects any errors/warnings in loaded bitstream. By clicking on the button switches to the list of detected problems. Double clicking on selected problem will navigate to the place where the error occurred.


Utilize Advantages to Increase Video Performance

With bandwidth a major cost to network streaming and infrastructure, the use of advanced codec like HEVC and AV1 is essential to improving compression while reducing bandwidth for real-time and OTT video streaming, content delivery, broadcast, and advertisements. With VQ Analyzer, users have the power to deeply investigate the new layers of complexity in next-generation coding pipelines and compare results with conventional codecs. VQ Analyzer has easy-to-use, rich visualization capabilities that can help users take advantage of more efficient encoding to reduce bandwidth needs―decreasing the risk of quality regressions in the transition.

With support for HEVC extensions including Screen Content Coding, Scalable HEVC and Multiview, SCC provides better efficiency for rendered content (desktops graphics). SHVC adds ability to react to changing network bandwidth to produce more reliable viewing experiences.


Dual View

Compare two bitstreams side-by-side to identify a difference and match every step to make decisions or root-cause an issue on. Enhance your product validation process with both visual and automated regression checking.

Informational Overlays/Maps are efficient tools to understand coding efficiency distribution.

  • Heat map (bit per pel), Efficiency map (bools per bit) to identify where most bits/bins spent and detect inefficiency of encoder
  • Reference Indexes, QPs, Block Types, Simple Motion Flow
  • per block PSNR for a loaded reference YUV

Details View

In each mode (Predictions, Residual, Reconstructed, Deblocked, Filtered, and Decoded Pixels), details view replaces Main View when user 'right-clicks' on a selected coding unit/block within a frame in Main View

  • Goes to per pixel view for a selected block, macroblock or CTU for each Main view mode
  • Prediction – every pixel value is clickable to see how it was formed from predictors
  • Residuals de-zigzag process, de-quantization and inverse transform
  • Deblocking edges, strengths and impacted pels
  • SAO directions and predictors
Details View

Statistics and Reports

There are never too many statistics. VQ Analyzer provides many different kinds of data in text and chart formats to help you view, prioritize and target optimizations.

  • Frame level: total pits/bytes, bypass bits, MD5/CRC
  • Motion Vectors direction and Reference list utilization
  • Visual charts and dump to a comma separated file for future use or further analysis
  • Frame level statistics for Intra, inter modes, Prediction modes, TU, CU, PU and Partition types and many more needed for a developer
  • Raw values and normalized by area or bits used

Buffer Analysis

  • VBV visualization
  • HRD buffer compliance
  • Moving average of buffer fullness
  • Frame size and frame type
