Description Oliver Sander 2013-10-18 10:33:30 UTC
I use the LaTeX 'multimedia' package to show movie files within my pdf presentations.  The package has an option 'showcontrols', which should show & enable the movie player controls while playing the movie.  This does work, but only during the first time the movie is played.  Clicking on the movie again to play it a second time plays the movie, but the controls are not there.

I can make the controls reappear by either reloading the file, or by switching to presentation mode (or back).

Reproducible: Always

Thanks, Albert.  Maybe it's too late in the day, but I don't actually see any difference with the patch.  The bug is still there.  Is that possible?
Comment 6 Albert Astals Cid 2013-10-20 16:09:42 UTC
It's probably too late in the day.
Comment 7 Oliver Sander 2013-10-28 20:50:01 UTC
I have recently updated my entire system to Debian testing, and recompiled poppler and okular (from git master) from scratch.  That was earlier in the day :-) still I keep having the same problem as described originally.  Albert, can you recommend something that I could do to help and debug this?
Comment 8 Albert Astals Cid 2013-10-28 23:00:20 UTC
Only reason i can find is that you're not compiling or running it correctly. Add some code that crashes in VideoWidget::play, compile and run, and if it does not crash, it's because you're doing something wrong.

Some code that crashes:
int *a = 0; *a = 33;
Comment 9 Oliver Sander 2013-10-29 13:16:34 UTC
I purged the system okular + libraries from my computer, just to be sure I am not secretly starting that one.

I cannot make okular crash by placing that line into VideoWidget::play, and not by putting it into the VideoWidget constructor, either.  I can make it crash, however, when putting it into main(), or into Shell::fileOpen().  Does it make sense to try more places?  Since I don't know KDE/QT programming I would need some help on what places to try.

Read the last bit of http://okular.kde.org/download.php
Comment 11 Oliver Sander 2013-10-29 14:11:34 UTC
Oh stupid me.
I know what it says on that page, and I had followed those instructions.  But on rechecking I remembered that I had a second old instance of okular compiled and forgotten a while ago in a temporary directory.  And of course the relevant paths pointed to that one first...
Anyway, apologies, and many thanks for your time.
Comment 12 Albert Astals Cid 2013-10-29 14:22:28 UTC
Just to confirm, the fix is working, right?
Comment 13 Oliver Sander 2013-10-29 14:35:23 UTC
Yes, thank you.
