National bodies that are members of ISO or IEC participate in

6、 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

7、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. The procedures used to develop this document and those intended for its further maintenance are described in the IS

8、O/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibil

13、e 1, Scope Replace the following: Currently the following standards/profiles are included in ISO/IEC 23002-4 and in this part of ISO/IEC 23002 as reference software ISO/IEC 14496-2 Simple Profile, ISO/IEC 14496-10 Constrained Baseline Profile, ISO/IEC 14496-10 Progressive High Profile. with the foll

14、owing: Currently the following standards/profiles are supported in ISO/IEC 23002-4 and in this document as reference software ISO/IEC 14496-2 Simple Profile, ISO/IEC 14496-10 Constrained Baseline Profile, ISO/IEC 14496-10 Progressive High Profile, ISO/IEC 23008-2 Main Profile. NOTE The reference sof

15、tware supports the decoding of bitstreams that conform to the Main Profile of ISO/IEC 23008-2, but does not support display-related features indicated in supplemental enhancement information (the support for which is a display capability that is outside the scope of ISO/IEC 23008-2).

16、 9 Replace the electronic attachment as found attached; which includes the prior reference software and adds a new “mpegh” subdirectory. The “mpegh” directory contains functional units and networks allowing decoding of the ISO/IEC 23008-2 Main Profile. ISO/IEC 23002-5:2013/Amd.2:2017(E) ISO 2017 All

Annex A (informative) Information on compiling the RMC reference software This annex provides information on how to comp

18、ile the reference software of ISO/IEC 23002-5. Like most software written in other programming languages, such as, for example, C, C+, Java, Verilog, or VHDL, the reference software written in RVC-CAL according to ISO/IEC 23001-4 first needs to be compiled in order to be executed on a processing pla

19、tform. Since, in general, current processing platforms do not support RVC-CAL with platform-specific compilers, an RVC-CAL program needs to be cross-compiled into another language that is supported on the processing platform that is chosen as the program execution environment. Any ISO/IEC 23001-4 RV

20、C-CAL compliant cross compiler could be used for this purpose. For instance, the Orcc cross compiler available at: http:/ / supports, for C and some other programming languages, the cross compilation of the reference software provided with this document.2 ISO 2017 All rights reserved ISO/IEC 23002-5:2013/Amd.2:2017(E) ISO/IEC 2017 All rights reserved ICS 35.040.40 Price based on 2 pages
