AFAIU we plan to: * work on Voctomix * work on our hardware (what we are going to buy, travel cases, etc.) * work on the Opsis * work on having a better streaming I personally want to document the shit out of our things. I feel a lot of the things we use are known by one or two people only in our group and that makes me sad :( As for all the technical opsis-y stuff bellow, nice to see things are moving! I'm sure some of use will be thrilled to work with you on this during the sprint. -- pollo > A couple of things which I would really love to see done are; > > * Finish the VGA board changes. > - This is currently pending on RattusRattus changes around the ESD > protection. > - Once this has been finished, I can get my PCB designer to finish the > routing and we can look at getting them made! > > * Getting the HDMI2USB-mode-switch tool ( > https://github.com/timvideos/HDMI2USB-mode-switch) packaging for Debian > (and getting upstream). > - This tool will be the primary mechanism for people to manage their > HDMI2USB compatible boards and do things like upgrade the firmware on them. > - There are some custom udev rules included with the tool ( > https://github.com/timvideos/HDMI2USB-mode-switch/tree/master/udev) which > probably need hitting with a stick to be acceptable (they current set > things to permission 0666). > - There are extra features that I would love to add but these are not > Debian specific things (IE Checking the existing firmware version and then > downloading newer firmware from the prebuilt repo). > > * Start using the HDMI2USB-controlproxy-daemon ( > https://github.com/timvideos/HDMI2USB-controlproxy-daemon) and packaging it > for Debian. > - This tool converts the serial interface into a TCP socket and works > around problems with the crappy serial implementations.
