[FFmpeg-user] avfoundation on osx 10.7.5: issues with audio input

[John Robinson]

I'm trying to record both screen and audio on an older intel mac mini (circa 2009). The machine is running OSX 10.7.5. I've been able to compile and test ffmpeg on my other mac which is running OSX 10.9.5 just fine. 

So far I've tried the following on the 10.7.5 machine....

./configure --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass  --enable-libx264 --enable-indev=avfoundation
make && sudo make install

It compiles and installs fine, but when I run the following:

./ffmpeg -f avfoundation -i "0:0" ~/Desktop/screenout.mpg

I get this response:

If I change the ./configure like so:
./configure --cc=/usr/bin/clang --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass --enable-libx264 --enable-indev=avfoundation
make && sudo make install

and then run:
./ffmpeg -f avfoundation -i "0:0" ~/Desktop/screenout.mpg

I get the following output:

0:0: Input/output error

As a side note, I've modified 'configure' . I've removed the -framework CoreGraphics bits since ffmpeg wouldn't compile with those bits included. I also tried changing it to ApplicationServices which compiled, but resulted in the same 'audio format is not supported' error when I tried to capture audio. Anyone have any thoughts? I don't know enough objective-C to modify avfoundation.m to give a more descriptive error message but if anyone wants to point me in the right direction I'll gladly give it a whirl and try to capture any more details as to what's going wrong.

Thanks!
