Hi @daz,

I've read through the forums, and done some searching. Apparently, this is a common thing with this software and it's binary installs. That said, there seems to be a general stance from the producer of the software to try newwer versions (which fix these issues) or to do what you'd also tried, the source install.

To get the extra component that you seem to be missing, go ahead and install ffmpeg and if that doesn't help, try ffmpeg-dev or ffmpeg-dbg depending on your distribution.
