dear all,
unfortunately i'm forced to work with a mediaserver that is not capable to do a live-cam freeze. now i'm trying to solve this by building a osc-controlled blackbox with GEM (pix_buffer[read/write]).
test-setup: decklink quad 2-8 capturecard https://www.blackmagicdesign.com/de/products/decklink/techspecs/W-DLK-30 in sonnet frame macbookpro (2013)
this testpatch works ok, but with 500-1000ms latency ... https://zimt.at/cam_freeze_v01.jpeg
question:
how can i push the latency and make it more "real-time" (whether with pix_buffer or several pix_buffers or other objects)
do you have experience how to push the GEM output to the decklink sdi-out? i guess the rendering is done on the graphics card and not on the decklink (?not openGL capable?) so mabe this is useless? so is the macbookpro graphic card the bottleneck?
merci marco
