Why mp4 or mp4.ts from identical installation?

You won't get any support for Flash or rtmpdump.  They have been deprecated 
for some months, and have been withdrawn in v2.98 of get_iplayer.

You don't say which version of get_iplayer you are using or which Flash mode 
you are trying to receive.  If you have v2.95 or above you can use the HLS 
modes.  If you have been receiving Flashhd, try tvmode=HLShd

You can find a table of modes available in v2.98 at
