Right, you mean qtvideo-node. Thanks for reminding about the inclusion
of those private headers, they had indeed changed.

With the attached MP video playback works again.

Ok it's possible to gdb -p [pidofmediaplayer-app] to get:

#9  0xb5df6490 in start_thread () from /lib/arm-linux-gnueabihf/libpthread.so.0

That's probably as far as I can get there, and the trace doesn't show
any hints why video playback works for eg thumbnailer + in Youtube but
not in media-player - nothing related to qtvideo-node shown for example,
and the backtrace does not go further back because of corrupt stack.

Any help welcome.

[Touch-packages] [Bug 1474695] Re: Video playback broken with Qt 5.5

[Jim Hodapp]

Thanks Timo. It looks like this is a regression or change of behavior in
how the Qt threaded renderer works. Perhaps it has a new requirement for
how a QSGVideoNode needs to be setup. Another thought: we brought
QSGVideoNode into qtubuntu-media, maybe the definition used by the
threaded renderer loop has changed for Qt 5.5 and we need to update our
local copy of it.

Can you get the log for mediaplayer-app as well? This will have the
qtmultimedia/qtubuntu-media debug output.
