Can't build dr_meter

[scus1]

Hi there, I tried to build dr_meter and got the following error. I am using Debian Wheezy and libavformat-dev 6:11-1.

Same in 2018

I downloaded all branches of libav from https://libav.org/download/#git and tried building magiacl and adibol forks with each of the libav version (0.8.21, 9.21, 11,12, 12,3, snapshot). None of them seem to be compatible! The least amount of errors is with magical fork and libav-12,3 / libav-snapshot

Could you, please, add a link to the version of libav that you are using?

I managed to build it after making some fixes. See https://github.com/adiblol/dr_meter/pull/5.
