It is true.
After looking at what exactly was needed, I reduced it to a very simple
bridgesupport file :D
At first I thought it would be a bunch of inter-dependant bridgesupport files,
but looks like it was way easier than that :-)
<?xml version="1.0"?>
<!DOCTYPE signatures SYSTEM
"file://localhost/System/Library/DTDs/BridgeSupport.dtd">
<signatures version="0.9">
<cftype name='CVBufferRef' type='^{__CVBuffer=}'/>
</signatures>
Add this into a file like QTKit-capturefix.bridgesupport, and call this line
just after QTKit:
framework 'QTKit'
# Fixes the call to
captureOutput:didOutputVideoFrame:withSampleBuffer:fromConnection:
load_bridge_support_file '/path/to/QTKit-capturefix.bridgesupport'
Hope this helps :-)
