The obvious non-standard item is Project-X, which I build from the 
tarball; that needs java openjdk to run and and openjdk-devel to build.

You could set USEPJX to false and use the python script instead, but the 
output will then include secondary-language and data streams - and 
perhaps reception errors - and will therefore be bigger, and the cuts 
won't be as clean as with USEPJX true.  There's no heavy-duty 
transcoding involved and the java seems quite efficient, so most of the 
time taken is file-shuffling.
