Framegrabber on a client

vvvv beta question
1

hello,

here is something i plan to do:

to have external video-input grabbed by 2 boygrouped computers and splitted over 4 screens each.

not having been in a boygroup before, this still raises some problems i want to have considered before getting to it:

  • if the framegrabbers on client and server are not identical, will a boygroupped video-in inherit the client’s format/standard/input/driver enumerations ?

  • in a single-system setup with video-in tiled over multiple displays, i had to parse the signal over shared memory; how does this apply in boygroup ?

  • is Device(ex9 manual) useable in boygroup for decinding wich renders fullscreen on what ‘adapter’ ?

thanks

    the enums will be different as they will always reflect the actual hardware/driver on each client. therefore it may be difficult to select the right settings if they are on different entries in the enum. besideds being an ugly workaround, using Ord2Enum (Enumerations) and the clients id it should still be possible to select different enums on each client.

    exactly so.

    yes, should be. if this is really your what you want to do?! basically the idea of a boygroup is that server and clients hardware are absolutely identical and you don’t have to treat clients individually. just place renderwindows on a monitor on the server where they are supposed to fullscreen and they’ll do so on the clients.

thanks, it worked out just fine on the twin systems.

    how about the server not being used for redering, as stated in the documentation. in this case, do i need the server to carry as many videocards as the clients, as to be able to fullscreen in the proper places on the desktop ?
