Dan,
Thanks for your response. I read both articles and understood why this
isnt a good idea! :(
The thing with wanting to use two different computers is that one will have
two Decklink cards (one for input, one for output) and will be processing
some filters for the output. Im afraid that I will run out of processor if
I try to encode a stream on this same machine. On the other hand, I have
another computer, set up for transcoding with two beautiful processors.
But I cant put a Decklink card on it (its 1u rack) nor a shuttle (lacks of
usb3). So I was wondering how could I send the input from Decklink card to
this transcoding server... Discarding UDP, do you think is any other way of
doing this (FIFO, UDS, SHM??). Im on linux but am not a linux master. In
the past, one of my colleagues did a Producer that used SHM for passing the
Frame object through to n Consumer. But this worked on the same computer,
I dont know how to do something like this for work on different computers
(if possible).
Thanks again!
Juan Martin
