I am trying to compile MythTV on MacOS X for the first time after
Daniel committed the Xv-XvMC patch and I am having problems with
videoout_quartz.cpp. It seemes that the data type CodecType is defined
both in libavcodec/avcodec.h and in QuickTime.hThis is my fault, I added avcodec.h to videooutbase.h for the CodecID type. Is it difficult to put QuickTime.h into a namespace? Putting avcodec.h in a namespace requires changing many files.
Tried that and got mythtv to link, but as soon as I selected "Watch TV" it crashed with the following backtrace:
#0 0x908311ec in objc_msgSend ()
#1 0x96547a0c in numberForKey ()

Maybe I'm on the wrong track but my guess is that CGDisplayCurrentMode() was calling a QuickTime function whose name got mangled because of the namespace.
I can look into this if you like (now that I know that this isn't just a setup problem on my end). I'll see if I can split videoout_quartz into two files, and have different #includes in each. If I can get it to link that way and still get a crash, then we can add a namespace and start looking elsewhere for the cause of the crash :-)

Thanks Daniel, for fixing the #include problem. Unfortunately it did not fix the crash in VideoOutputQuartz::Init(). I did a bit of debugging and discovered that CGDisplayCurrentMode() was referring to data that DisplayResOSX::GetDisplaySize() had incorrectly deleted. I have attached a fix for this, as well as a small #ifdef to prevent the Mac build from #including videoout_xv.h
