AVC, MPEG-1/2, HEVC, VP9*, VVC*, AV1*

Video Formats that are supported

Raw reference file support

Allows estimating quality of encoded stream against the raw reference stream and calculating quality metrics, such as  PSNR | APSNR | SSIM | DELTA | MSE | MSAD | VQM | NQI | VMAF and VMAF phone | EPSNR | VIF at various steps: decoded, predicted, unfiltered, residual.

Not available

Comparison of the encoded file with the reference / raw file

Binding mode

Allows synchronization of the selected frame and block position with similar frame and block of a stream opened via another StreamEye instance running in the system.

Not available

Comparison of similar blocks or frames in the same position in different streams

Stream Presentation/Charts

BarChart

All parameters of the Barchart are available except for EPSNR (Estimated Pick to Signal Noise Ratio).

Statistics data representation in barcharts and graphs. Easy navigation throughout the stream frames using several stream presentation types

The bar height illustrates the frame size in bytes and the bar color indicates the frame type. Presentation order, scale, bitallocation lines, reference markers, sizes, metrics, quantizers, EPSNR, DPB occupancy parameters are shown. Tooltip with thumbnail, frame position in the stream, type, timestamp, quantizer, offset, picture order count, size is displayed for each frame.

Area Chart

Not available

The Area Chart navigation control shows bit distribution in the stream. The control allows choosing bitstream elements to display: skipped macroblocks, macroblock and prediction types, transform data, flags, quartier delta. Tooltip is added.

Thumbnails

Not available

The Thumbnails navigation control shows the video stream using the frame thumbnails. The thumbnails are underlined with color indicating the frame type. The stream/display frame order is specified with digits below thumbnails. Tooltip is added.

Info panels

Stream

All parameters of the Stream panel are available except for bit distribution in the coded elements.

Detailed information on each and any component of the stream

The Stream panel displays the stream summary information: profile, compatibility flags, level, tier, chroma format, resolution, frame rate, duration, frame types, average frame sizes; range of quantizer values; bit allocation info; frame average bit distribution in CU.

Picture

All parameters of the Picture panel are available except for bit distribution in the coded elements.

The panel displays the frame summary information: CU, PU, TU size (in bits); max\min QP; pixel distribution into encoded type (intra, inter, and skip); motion vectors range; bit distribution in CU.

Block info

The panel displays Mackroblock /Suberblock/Coding Tree Unit/TCU information: location, slice idx, tile idx; sizes; coded unit, predicted unit, transform unit info.

Headers

Not available

The panel displays the bitstream headers that are used for the selected frame decoding and display. Header parameter values along with indication of their compliance to the standards are shown.

DPB info

Not available

The panel shows the Decoded Picture Buffer information for the selected frame. The DPB panel supports display for AVC and HEVC video.

Block Presenter

Not available

The panel provides block visualization for smooth navigation and detailed information on CU parameters. Shows processing stage of a frame, overlay parameters: partitions, motion vectors, types, background; values for the selected block: predictions, sizes, quantizes.

Statistics  

Not available

The panel displays statistics on streams or selected frames and can be shown either by count, or by area: distance between I frames, P Frames, B frames and Key frames; macroblock types and dimensions, prediction and transform info  and additional information depending on the stream type.

Tools

Stream Viewer

Helpful instruments addressing specific areas of investigation during bitstream analysis

The stream viewer displays a structure of headers belonging to the opened stream in the text mode. The stream internal structures are expandable.

HEX Viewer

The viewer displays a stream in the HEX mode. The display is synchronized with the stream position.

Pixels Viewer

Not available

The viewer displays pixel YUV values for different decoding steps (decoded, predicted, unfiltered), coefficient values (residual, transform, dequantized), reference (if opened) and difference (if selected and exists).

After Deblocking и AfterSAO are also available for VVC streams.

Message Viewer

Not available

The viewer displays messages on compression standard compliance for the stream. The Message viewer  supports display for AVC and HEVC video.

Buffer Analyzer

Not available

To ensure the system operational reliability, the Decoder Video Buffer parameter analysis is performed. The Buffer viewer displays results of the analysis (for AVC and HEVC video formats).

The controls allow adjusting chart presentation and show main parameters that are used for the buffer calculation along with their values.

Picture difference comparison

Allows picture comparison between decoded, predicted, unfiltered, residual, reference and memory stages and showing the difference in Compare, PSNR, PSNR clip, Subtraction, Temperature modes.

Not available

Visual representation of picture difference at several processing / decoding stages based on a set of comparison criteria

Memory

The frames can be memorized  at various processing stages: decoded, predicted, unfiltered, reference.

Not available

Easy selection of a specific frame for further comparison against the current frame
