You need to install from the image feeds, as these are compiled with the image,

so...
opkg update
and then install everything you need with the command below,
opkg install ffmpeg exteplayer3 enigma2-plugin-systemplugins-serviceapp

You need to send these 2 commands from telnet/ssh command prompt when you are connected to your box.
