Dear list,

i reactivate an old patch with pd 51.2 and Gem 0.94 on OSX 10.12.6. Super nice that Gem works with the 64bit version of Pd nowadays!!
I have a problem with [pix_record] testing with the help patch, i get this error:

[GEM:recordQT4L] couldn't initialize codec
[GEM:recordQT4L] unable to initialize QT4L

pressing [codeclist( does not give anything.
pressing [codec 3( gives
[pix_record]: invalid codec# 3 (0..0)

Should i change the backend? If so, how? Should i install QT4L on OSX??

Many thanks in advance,

Jonas
