5.3Summary of discussions

M18382

A set of conformance sequences produced by GPAC have been uploaded in this contribution (mp4 and xmt). Another set of files in the used by bifsenc/mux in IM1 is also provided.

There is no repository for sequences, so where to put them ?

This should go to the WD on BIFS ExtendedCore2D profile conformance

M18383

IM1-2D has been updated to reflect the latest versions of BIFS. The project files were updated to Visual Studio 8 (and should be upgradable easily now). MPEG-J support is not activated because it could not be rebuilt. Some 3DGC code needs some help.

Parsing, decoding and encoding of the new tools is functional for nodes and commands. There is utility software to check the behaviour of the nodes (GPAC). So there are two interoperable open implementations of the standard.

This should go into a WD of BIFS ExtendedCore2D Reference Software.

This raises the question of free readonly access to the MPEG SVN.
The five contributions are presented together through m18417.

m18407: question about the virtual lab, sharing a lab software, clarification that if there is software, it is on the server, and all communication with the software is managed by the collaborative environment.

m18408: what is the specificity of this use case ? possibly the security/privacy issues, and how to establish and communicate trust.

m18409: specificity is the mobility, the sharing of high quality material and the variety of usage environment, but not so collaborative.

m18412: session migration, collaborate on external software, remote upgrades

There is a missing tool on allowing collaboration on external software, a sort of extended VNC.

Should it be connected to BIFS? No! We should specify what are the needs: a scene description format, possibly XML-base, with events, maybe an update mechanism (but could be in the collaborative layer).
M18422

This describes using mosaic of images to share an application within a BIFS environment. The criticism expressed in the contribution was clarified to be criticism of the GPAC implementation, not of the standard. Guidelines were provided to the author about the proper use of CacheTexture, once the implementation in GPAC has been improved.

7.3Summary of discussions

m18529:

the contribution was presented, together with further discussions on the reflector. Some of it comes from a misunderstanding, and further discussions on the reflector may be needed. However, the contribution cannot be accepted.
