[Pianod] Pianod2, Internal Server Error

[Peter Li]

What raspi distro are you on?

I had to make some minor changes to fundamentals.cpp to get it to build
under gcc4.7.

But I'm not able to get audiooutput.cpp to build, apparently due to my
libavfilter being too old and buffersink.h not having
av_buffersink_get_frame.
