h2. Use-case Analysis Presentations

* Stefan
** Spread cross-compiling does not work well
** RSC more fine-grained because one single library to load wastes memory
*** build all smaller libs with one CMake but configure via options what is required
** Make tests and spread binary finding optional in RSB
** How to map CAN messages to RSB messages (Shadow Hand uses a more complicated protocol than Stefan's robot)
** Performance requirements:
*** 1 Mbit on the CAN bus
*** Marshaling could waste CPU
** Robert and Stefan will further discuss what is required to build a more or less generic CAN ti RSB bridge
* Florian
** Sending and receiving in a gstreamer pipeline using RSB
** Audio missing
** Overview about available classes
** nearly easier than XCF
* Christoph
** tasks
*** high-level data, IPC
*** **** how to use or define common types for this (type-safety vs. flexibility)
**** ***** Frederic: e.g. starting from BTL and ROS messages
**** ***** make a publicly available repository that is visible
*** **** migration path from XCF
** *** video
*** **** for one computer there's a shared memory solution existing (later to be ported)
*** **** common types for images as protocol
**** ***** support compression (e.g. run-length coding)
*** **** avoid extensions to this type(?)
* Robert
* Johannes/Jan
** Conditional Sending (see above)
*** Problem statement and requirements
*** Implementation Plan
** Inter-Segment Communication
*** Clarification
*** Documentation: wiki page
