Display MoreHi, I'm answering myself and for those who are looking for the solution for streamlink....
Menu/Settings/Software management/Advanced options/Package management
Scroll down to streamlink and click OK to install. Confirm the query with Yes.
Close with the red button.
Answer the reboot request with no.
Press RED repeatedly until the sleep/restart selection appears.
Select restart (not GUI restart)!
------------------------------------
If TV image + sound are present, then again after:
Go to Menu/Settings/Software Management/Advanced Options/Package Management.
Scroll down to streamlinksrv
(if you did everything correctly in step 1,
the globe on streamlink should now be colored)
Now install streamlinksrv with OK
and confirm the query with Yes.
Close with the red button.
Answer the reboot request with no.
Press RED repeatedly until the
sleep/restart selection appears.
Select reboot (not restart
of the graphical interface).
After reboot, streamlink addresses
should now light up!
and to check in package management,
check if both globes are colored.
"opkg install streamlinksrv" from telnet then reboot and you're good to go
