Any help, please?

Have you build libopenshot-audio already?

[onzone]

Yes..I have build libopenshot-audio..And it built fine..

Ubuntu 16.04 has entered what Ubuntu calls "Extended Security Maintenance" (as of April 2021), basically it's no longer supported except for paying customers with critical issues with the core components.

It's therefore no longer supported by OpenShot/libopenshot, sorry. (You could build on it, but you'd have to upgrade CMake and FFmpeg at a minimum. Possibly GCC as well.)

[ferdnyc]

Oh! And Python. We've stopped supporting Python 3.4 and 3.5, which are both now end-of-life.

[ferdnyc]

Ah, it looks like you have upgraded those things — that's good. The issue you were actually seeing was a boneheaded mistake I made in the FFmpeg linking, but it's now been fixed by #693 and #694. Try the latest develop code, it should do the right thing.
