Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 23000-10:2012 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information
technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.

AMENDMENT 1: Conformance and reference software
after 6.4.3.3 add the following two new clauses:
7 Conformance
7.1 File conformance
A file is said to be conforming when the following conditions are all satisfied:
— Brand consistency: the major_brand matches the declared brand name.
— Format conformance: the structure and syntax of the boxes included in the file accomplishes the
conformance procedures defined below.
— Component conformance: all the included components in the file such as video data and audio data
conform to the corresponding coding and file format specification.
— Additional boxes beyond of those required by this specification might be present but are not required
to interpret conforming components correctly.
7.2 Parser conformance
A file parser is said to be conforming when the following condition is satisfied:
— The parser can correctly parse any conforming file and subsequently an appropriate player play the
media components included in the file.
7.3 Creator conformance
A file creator (or authoring tool) is said to be conforming when the following condition is satisfied:
— The creator can produce files that a conforming player can play.
7.3 Conformance points
For the file format, the following conformance points shall be checked for conformance testing.
C1 – conformance point 1
— Check that the major_brand identifier is ’sff1’.
— Check that there is at least one fragment contained.
— Check that at least one metadata box is present
— at file level and
— for each media track at track level.

ISO/IEC 23000-10:2012/Amd.1:2014(E)
C2 – conformance point 2
— Check that each “AF Identification Box” contains a valid UUID identifying the fragment.
— Check that each “AF Identification Box” contains a predecessor UUID referencing the predecessor
fragment or the current fragment if no predecessor exists.
— Check that each “AF Identification Box” contains a successor UUID referencing the successor
fragment or the current fragment if no successor exists.
— Check that the “Camera/microphone Identification Box” for each track contains a valid UUID.
C3 – conformance point 3
— Check that all fragments use the same number of tracks.
— Check that for each media track a timed metadata track exists linked using a track reference of type
‘vsmd’ for video tracks and ‘asmd’ for audio tracks.
— Check that media tracks using identical media coding parameters exist in all fragments.
— Check that all media tracks for each fragment start with a random access point.
— Check that each fragment start with an instantaneous decoding refresh access unit if the sample
entry type avc1 is present.
C4 – conformance point 4
— Check that the duration parameter given in the “AF Identification Box” coincides with the duration
parameter in the “Movie Header Box”.
— Check that boxes of version “1” being used for “Track Header Box”, “Media Header Box” and
SurveillanceMetadataSampleConfigBox.
— Check that following box types are not used: shadow sync sample, SampleGroupBox (‘sbgp’,
‘sgpd’), SampleGroupDescriptionBox, ‘subs’, ‘stsl’, ‘imif’, ‘ipmc’, ‘avcp’, ‘iods’, ‘mp4v’, ‘mp4s’,
MPEG4BitRateBox, and MPEG4ExtensionDescriptorsBox.

8 Reference software description
The reference software is split into three separate modules. A creator module allows for compliant file
generation, a parser module interprets given files and a framework module embraces the core libraries
required.
8.1 Architecture
The architecture of the software is depicted in Figure 1. The software has been designed as standalone
implementation, independent on any SDK and additional tools, and multiplatform capable of compilation.
The design principle used is object oriented programming.
Each box derived from the framework has an auto validity check.

8.1.1 SAF Framework
A generalized function module, configurable and extendible.
Main features provided are:
— Instantiation of boxes conforming to the ISO Base Media FF and the Surveillance AF
— DOM structured containers
— Validity checking of all levels in the DOM
— Functionality for inserting and removing boxes, containers or root containers (DOM tree size is
automatically adapted)
Figure 1 — SAF reference software components
8.1.1.1 LibIsoBaseMedia
The library provides items and containers conforming to the ISO Base Media FF specification. Additionally
it provides for:
— Basic item check
— Visualization of the container-box DOM structure
— error report mechanism and error concealment (can be switched on and off)
NOTE The library files and items use the prefix ISOBMF for name convention. The individual names are
generally identical to those from the related standard.
8.1.1.2 LibIsoSurveillanceAF
The library provides items and containers conforming to this specification. Features provided by
LibIsoBaseMedia are preserved.
8.1.1.3 Utilities
Utilities are used to create more specific boxe
