How to compile on Ubuntu 14.04?

Hi
I'm trying to compile the freej master branch on ubuntu 14.04 and keep getting the error:

Can I build freej on a recent ubuntu?

[jaromil]

FreeJ needs a version on FFMpeg preceeding the complete overhaul and devastation that has been done to its API.

I am considering to restore static linking of FFMpeg as it was before being included in Debian

(Debian has first included FreeJ recommending such a change, then it has removed it from packages. How nice of them!)

[jaromil]

As @diorcety is working on FreeJ 2.0 I see this may be a fix diorcety@05d0bc8

[diorcety]

Maybe, it is not tested, it takes the code from the old function,brainlessly ...

[ricardogsilva]

I'll try using @diorcety repo to see if it builds. If not, what version of ffmpeg would I need to compile and link with the freej source?

[jaromil]

I'd go with any of the 1.x releases maintained by Niedermayer https://www.ffmpeg.org/olddownload.html and recall using 0.10 "Freedom" succesfully, may also work up to 1.1
