Generally, on this mailing list, only current FFmpeg git head is supported. 
(Among the reasons are that our man-power is limited and that we can only 
fix issues in current FFmpeg git head, non-security patches are normally 
not backported.)
There is also a bug tracker for FFmpeg on Ubuntu but you would likely be 
asked to test current FFmpeg there as well.

Another reason for using current FFmpeg git head is that we now have a 
better default aac encoder.

> frame=  666 fps=8.0 q=-1.0 Lsize=    2496kB time=00:00:22.20 
> bitrate=  920.6kbits/s

This status line indicates that no frame was dropped or duplicated while 
(Although I realize you didn't post your command line, it is possible to 
create command lines that drop and / or duplicate frames without showing 
anything suspicious in the status line.)

Feel free to provide an input sample.
