Release Notes v5.3

VQ Analyzer 2020
Release Notes ver 5.3
Overview
The VQ Analyzer is a graphical coded video bitstream analysis tool, supporting
the following coding standards:
VVC, SHA-1 (VTM 9.0 tag):
5d7f8127910f424c592fa26f09e3170082ad885a
AV1, SHA-1 (av1-normative branch of AOM source):
acc3f97753f67e0ce7290b98b7bb71152fe5e264
HEVC: (ISO/IEC 23008-2 MPEG-H Part 2 or ITU-T H.265) , 8/10-bit
HEVC: RExt extension, 8/10/12-bit, 4:0:0/4:2:0/4:2:2/4:4:4
HEVC: SCC extension, conform to HM + SCM 8.6 in reference code
HEVC Scalable/Multiview Extension
Google’s VP9, profiles 0,1,2,3, 4:2:0/4:2:2/4:4:0/4:4:4, 8/10/12-bit
AVC: (H.264/AVC, ISO/IEC 14496-10, MPEG-4 Part 10), except
SVC/MVC
MPEG2 (ISO/IEC 13818-2 Part 2), 4:2:0/4:2:2, 8-bit
MKV, MP4, MMT(ARIB STD-B60 1.0), MPEG2 TS/PS, AVI, ASF, FLV,IVF containers
Once a bitstream is loaded, the tool allows the user to inspect each major stepof the decode process visually and numerically, and the structure of the coded
image can be explored. This data can be used as a visual reference whenlearning about HEVC/VP9/AVC/MPEG2/AV1/VVC or when debugging aparticular encoder or decoder.

Package Contents
content: VQ Analyzer Release Notes (this file), VQ Analyzer User Guide,licenses, binary executables, tool’s internal and third-party binaries.

Installation
To begin installation: - Double-click on the executable file to begin installation.
Activation during installation You must activate the product to finish installation.
Use one of these methods: - Activation using serial number. Internet connection
is required; - Remote activation using serial number. Used when your computeris not connected to the internet. You can use another computer with internet
access; - Activation using license file; - Activation using license server. - You
can also evaluate the product for trial period.
If you have problems with installation under MacOS*, please, check System
Preferences -> Security & Privacy options under “Allow apps downloaded
from:”. The option “Mac App Store and identified developers” should bechecked.

Known Limitations
The VQ Analyzer has the following known limitations: - AVC/HEVC HRD buffer
fullness uses only Type II bitstream for visualization. - Archive yuv files (.zip, gz)
fully unpacked in memory currently, huge files could require a lot of memory. For zip files only first file in archive is considered to be used as compressed yuv
file. Only deflate and store compression methods are supported. - Archived y4m
files are not supported yet. - AVC decoding does not support gaps inframe_num and slice groups currently.
AV1 limitations: - Memory consumption can be high on 4K resolutions.
HEVC Conformance checks: - Bitstream conformance to active profile, tier andlevel representation and HRD parameters is tested on general representation
only. (PTL syntax elements with prefix ’general_’) - Bitstream conformance toHRD parameters is tested using VUI parameters specified in active SPS only. For Intra only profiles picture reordering is not tested. - Common Multilayer
HEVC: external base layer configurations are not supported. - HEVC Slice dataerrors: bitstream restrictions specified SPS VUI or VPS VUI parameters are notsupported.
HEVC Decoder behavior: - For Range extensions, High throughput and ScreenExtended (SCC) profiles in order to detect sub-profile (e.g. Monochrome, Main
444 12bit, …) bitstream constraint flags, coded in PTL, must be set according tothe tables specified in clause A.3 of the spec. - For Still Picture profiles test for
number of pictures present in bitstream is applied to whole bitstream file. - For
Screen-Extended (SCC) profiles in order to detect these profiles,general_profile_idc must be set to 31 or general_compatibility_flag[31] must be
set to 1. (same as of HM16.16+SCC8.5) (Will be changed to 9 (according tospec) in future releases) - Multilayer bitstreams are decoded with highest
available index of Layer Set (TargetOlsIdx is set to NumOutputLayerSets – 1).
All available layers will be output. - Different layers in Multiview HEVC stream
must have the same resolution and chroma format for inter-layer prediction.
(Configurations with different chroma format or resolution are still decodable, but
resampling process for inter-layer prediction will be invoked in that cases) - SCC
extensions presence in bitstream is tested on both position 3 and 6 of
sps_extension_bit and pps_extension_bit.
