Package: xbmc
Version: 2:13.2+dfsg1-4
Severity: important
Dear Maintainer,
when playing with xbmc from current jessie with activated xbmc-pvr-tvheadend-
hts
from some satellite broadcasts I get only a black screen when switching from
windowed to fullscreen mode.
These are the circumstances which are relevant (as far as I think):
- using a VDPAU enabled graphics card with needed vdpau libraries installed
- having no .xbmc directory in home directory (just for reproducability)
- starting xbmc
- activating Tvheadend HTSP Client addon
- playing a broadcast through LiveTv in windowed mode (in my case no HD
channel)
(plays fine in the partial screen with channels on the side as filling the
whole window too.)
- switching to fullscreen mode (e.g. altgr+backslash)
- video stays black, audio still playing, other menus and control elements also
visible.
I did some further investigations:
when changing "videoplayer.usevdpau" to false
(e.g. .xbmc/userdata/guisettings.xml, <usevdpau>false</usevdpau>)
then the video plays normal after switching to fullscreen.
I compared it to playing a DVD and I think in CDVDPlayer::OpenVideoStream
(which is
also used for my non HD channel) the "hint.software = true;" makes the
difference.
(DVDPlayer.cpp:2991, if DVDSTREAM_TYPE_DVD.)
I made a version which adds this "hint.software = true;" also to the next
paragraph
relevant for the addon.
(DVDPlayer.cpp:3003, if DVDSTREAM_TYPE_PVRMANAGER)
Then this black screen issue is not visible anymore.
I think this happens because on switching to fullscreen some X11 resources get
notifed in CWinSystemX11::OnLostDevice and therefore the
VDPAU::CDecoder::FiniVDPAUOutput
method is called.
Later every CDecoder::Decode call returns VC_ERROR because m_vdpauConfigured
get never true
again.

I opened it as important, but probably you want to increase it to serious if
you see fit.
If yes probably on way of action for jessie would be to add this "hint.software
= true;"
in DVDPlayer.cpp:3003 as it is already the case for DVD playback.
Kind regards,
Bernhard
