[GEM-dev] [ pd-gem-Bugs-2980652 ] [PD] strange colors with pix_record

[Matthias Neuenhofer]

yes the RGBA channels are set wrong on mac osx. the cube appears blue because the alpha channel is read as blue.
when you change channels like this 
R –> G 
G –> R 
B –> A 
A –> B
the movie will justified. but it´s not handy to give each record this process so  
i fixed this with a change in the code of recordQT.cpp in line 241 - instead of colorspace = k32BGRAPixelFormat;
i use colorspace = k32ARGBPixelFormat;
but i don´t know how this affects other os

also the recorded mov is upside down - this can fix in quicktime pro with a click in the properties of the video track -
so i don´t looked for the code issue.
