Compiling with recent avcodec/avformat libraries result in several deprecation warnings:

I'm trying to install qpsnr_0.2.5 on Ubuntu 16.04 but unfortunately it is not compatible:

$ sudo dpkg -i qpsnr_0.2.5_amd64.deb
(Reading database ... 379155 files and directories currently installed.)
Preparing to unpack qpsnr_0.2.5_amd64.deb ...
Unpacking qpsnr (0.2.5) over (0.2.5) ...
dpkg: dependency problems prevent configuration of qpsnr:
 qpsnr depends on libavformat54; however:
  Package libavformat54 is not installed.
 qpsnr depends on libswscale2; however:
  Package libswscale2 is not installed.

dpkg: error processing package qpsnr (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 qpsnr

Is there any plan to migrate qpsnr to Ubuntu 16.04?

Thank you.
