NoOOXML

Some delegations has attracted the attention on audio support on OOXML, asking for a list of supported audio codecs:

Delegations are asking for a list of codecs:

Proposed change: An interoperable set of formats should be specified.

Here is the ECMA non-answer:

If a rendering application cannot process external content of the content type specified, then the specified content can be ignored. [Note: A list of suggested audio types is provided in Part 1, §15.2.2. end note]

When you go reading the Part 1, §15.2.2, there is no list of codecs.

And the same issue and non-answer is for the video codecs:

Here is the ECMA non-answer, where they agreed to refuse to fix a list:

The video element does not specify the actual video file that is used by the animation; as such, we do not believe that it needs a list of potential codecs.

ECMA also does not fix the problems with another comment from Colombia:

ECMA continues to do not provide a FIXED LIST of supported video codecs:

Proposed Disposition
Agreed; the description of this element would be improved by referencing a set of suggested formats, as was suggested for other similar items (e.g. image formats) in other national body comments. However, we believe that rather than duplicate this information, we should just reference the list defined in Part 1. Also, we agree that this list should contain a set of portable codecs as the suggested base set. However, we do not believe that preventing the use of other codecs is appropriate, as it will prevent innovation. Accordingly, the following changes will be made:

Part 4, §2.3.3.17, page 259, line 5:

This element specifies a location within a document where the specified parent image shall be treated as a placeholder for an embedded movie. [Note: A list of suggested video types is provided in Part 1, §15.2.16. e note]

Part 1, §15.2.16, page 157, row

Content Type: Any supported video type.

[Note: Some example content types are:
video/x-ms-asf http://www.microsoft.com/windows/windowsmedia/forpros/format/asfspec.aspx
video/avi http://www.the-labs.com/Video/odmlff2-avidef.pdf
video/mpg ISO/IEC 13818
video/mpeg ISO/IEC 13818
video/ogg http://www.theora.org/doc/Theora.pdf//
video/x-ms-wm http://www.microsoft.com/windows/windowsmedia/forpros/format/asfspec.aspx
video/quicktime http://developer.apple.com/softwarelicensing/agreements/quicktime.html
video/vc1 http://tools.ietf.org/html/rfc4425//
end note]

ECMA removes some Microsoft's formats from the list of examples. Does that mean that ASF and WMV are excluded from the list of supported codecs? Of course not, it is a list of suggestions, and Any supported video type is supported, and the ECMA intentions are pretty clear:

we do not believe that preventing the use of other codecs is appropriate, as it will prevent innovation

And when it comes to address the reference to Quicktime, it is a patented format which requires royalty payments to MPEG-LA suckers.

Again, ECMA seems devoted to say: Good Bye Interoperability!

Also with Quicktime in another CO-0220:

Suggestion from the NB: Since Quicktime is a proprietary technology not covered within this specification, must cause the document to be marked as “extended” (See comment for Part 1, Section 2.6)

ECMA refuses to put it in the "extended" section:

while it is important to maintain this functionality in order to support the existing corpus of binary documents, we will update Part 1 and Part 4 of this standard as follows: Part 1, §15.2.16, page 157, Table 1: video/quicktime http://developer.apple.com/documentation/QuickTime/ softwarelicensi ng/agreements/quicktime.html Part 4, §5.1.3.4, page 3,294, line 2: This element specifies the existence of a QuickTime file, as defined in the 2007-09-04 version of the QuickTime File Format Specification http://developer.apple.com/documentation/QuickTime/QTFF/qtff.pdf . [Note: For more information on the QuickTime format: http://developer.apple.com/reference/QuickTime/ end note].

Quicktime, a proprietary and patented file format, is made mandatory to be compatible with old Microsoft Office 97-2007 binary file formats.

Again, say Good Bye to Interoperability!
