minidlna

It works even I use my phone to tether data (I don't need to turn on wifi on my phone).

sudo apt-get update
sudo apt-get install minidlna
sudo nano /etc/minidlna.conf # the default location of media files is on /var/lib/minidlna

# rebuild the database. See the comments in <etc/minidlna.conf>
sudo service minidlna force-reload 
sudo service minidlna start
sudo update-rc.d minidlna defaults # ask minidlna to start up automatically upon boot.

Too bad is when I played certain videos the program crashed. The /var/log/syslog showed kernel: [96495.690373] minidlna[1627]: segfault at 0 ip 00007f4af2de9964 sp 00007fffa43014f8 error 4 in libc-2.15.so[7f4af2d54000+1b4000]. Also the minidlna process becomes 2 instead of 1 after the crash.

Kodi

Too bad the Kodi's upnp function is not stable. Kodi server disappeared so the client cannot find it.
