yes please. it's hard to fix the issue otherwise.
you could try running Pd from the cmdline and in verbose mode ("-v") and
see whether you get something meaningful on the stderr.
Gem scans for gem_video-plugins both on startup and when you create a
[pix_video] object, so these are the times to watch out.
also, check whether the (runtime) linker can find all the dependencies
by running:
$ ldd gem_videoDeckLink.so
and looking for "not found" lines.
(but then, iirc, the DeckLink API uses dlopen() to open the actual
proprietary library, so "ldd" might succeed just fine)

Re: [GEM-dev] Blackmagic Deck Link Duo + Gem
Hi, The plugin .so file should reside besides Gem.pd_* Library file. Then gem will load it at startup, look at log level 4 in pd's console or at pd's terminal output to see debug info about where gem is looking for plugins and which one it loads My 2 cents A Le lun. 11 juin 2018 à 00:46, hi via GEM-dev a écrit : > so i try with the native backend for DeckLink cards. > unfortunately i know only half of what i am doing: > I managed to compile, as so that there are now .la + .so files but now > Pd+Gem does not load the backend.

Re: [GEM-dev] Blackmagic Deck Link Duo + Gem
[pix_video] gives an output on [enumerate( but using these numbers or names in the [device( message has not the desired effect. What works now is to use the [dialog( message and set the input by hand. unfortunatly I have to do this every time I open the patch. Thank you both for your informations concerning the linux backends. Probably I will have to use Linux for my project because of the limitation of RAM in a 32bit application (i use a lot [pix_delay]). > Am 08.06.2018 um 21:05 schrieb IOhannes m zmölnig : > > On 06/07/2018 12:05 PM, hi via GEM-dev wrote: >> Dearest Gem devs >> >> sorry for cross posting pd+gem >> >> I try to work with a Blackmagic DeckLink Duo 2 with 4 separate SDI inputs on >> OSX.
