|
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.

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 ¬Ú 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.
