Translucent display has broken phonon video

[Jonathan Corwin]

I thought it was too good to be true. It appears that by making maindisplay translucent I have broken Phonon videos. (Webkit still OK)

~crichter has discovered it relates to Qt bug https://bugreports.qt.nokia.com/browse/QTBUG-8119

Unfortunately just turning the translucent attribute on and off when required doesn't appear to work as the display stops redrawing when turning translucency off after it has been on.

** UPDATE: Partially fixed. This is now only a problem after someone has used a transparent theme. **

I seem unable to get phonon to even open a video file on Linux, let alone play it.

Therefore if there is someone who has had phonon working before and can give lp:~j-corwin/openlp/transparent a try and see if this plays videos under the phonon controller, please could you let me know how successful you are. Ta.

I can get phonon to open and play .mov and .flv (flash) video files on linux using 1.9.8.

I can still open them using lp:~j-corwin/openlp/transparent but when clicking the play button, the display screen just flickers briefly, and then all I get is audio.

Is this fixed?

[Jonathan Corwin (j-corwin)]

It is now fixed when no transparent theme has been used that session (r1892).

Still an issue for transparent themes, it will probably require the maindisplay to be recreated prior to video display.

[Jonathan Corwin (j-corwin)]

Downgrading this from Critical to High as there are now workarounds and it is fixed for many people.
(Either use VLC or don't use transparent themes which weren't available anyway when Phonon last worked)

[Jonathan Corwin (j-corwin)]

Downgrading to Low.
First of all no one has complained about the corner case when it doesn't work.
Secondly I don't think it is an easy fix, and certainly unlikely to happen anytime soon.

Link to QT bug report is no longer valid.
Due to it's age and the fact that it is in QT would suggest we make wontfix.

[Jonathan Corwin (j-corwin)]

Well it is something that is fixable (by recreating the maindisplay) just requires someone to be brave enough to do it.

The Qt bugs have probably moved to a Digia site now Nokia has offloaded it.

Is this issue http://support.openlp.org/issues/1262 to do with this or is it a seperate bug?

[Andreas Preikschat (googol-deactivatedaccount)]

Is this fixed?

[Jonathan Corwin (j-corwin)]

Unlikely

Closing bug as fixed in a later release.
