It should be relatviely easy to track down just by grepping for av_alloc_format_context and avformat_alloc_context in the ffmpeg build directories and/or install dirs.

Having said of course it would not be the first time an update has gone into ffmpeg only to come out again the next day

Or maybe the same day several hours later? I installed this morning, same error as everyone else except I went into the src folder and commented line 183 on the file the error showed.
Then this evening started from the beginning again and did everything the same and got no errors at all. Very strange, but I've captured all my work and it's uploading now.

Still no joy for me:

It should be make install-libs. That should do it for you.

Whichever one I try first, it's always the other one

Well haven't they always changed that at some arbitrary phase of the solar system.
As I recall 6 years ago was "make installlib" a year and quarter later became "make installlibs" a year and 5 months afterward s "make install-lib", eight months after which became "make install-libs".
It's been about a couple years now so I think it's due to change again
I think they just want to make sure your running "./configure --help" before each build to see what your options are

just wanted to make aware this "bug" is still in 1.24.1 but the above worked

I have just spent 45 minutes updating ffmpeg and ZM and I just don't get this error with ffmpeg SVN-r17785
The use of av_alloc_format_context is now deprecated and all instances should ve changed to avformat_alloc_context
