Bug#774038: xbmc: When going fullscreen watching through xbmc-pvr-tvheadend-hts makes video stays black

[Bernhard Übelacker]

Hello Bálint,

Tried now if I could get the SetFullScreen/CDecoder::OnResetDevice from
kodi into xbmc, but was not successfull on it (probably one with deeper
knowledge could do ...).

So in the end we have these options:

- turn off xrandr: affecting every video usage of xbmc
  (even affect non-binary-nvidia-driver users.)

- switch PVR to software decoding: just affecting PVR, but probably
  problematic on devices not fast enough for software (raspberry?)

- Let affected users change it via the confiruation interface:
  (at least Settings level Advanced)
   Settings - Video - Acceleration - Allow hardware acceleration (VDPAU)
  (guisettings.xml:usevdpau=false)

Kind regards,
Bernhard
