Sample Impress file with MP4 file with subtitles
This bug specifically affects KDE/QT desktop versions of the Linux operating
system.
(See associated bug 166807)
Description:
Impress presentations that contain MP4 video files with subtitles causes the
presentation to lock up. Mouse and keyboard input stop working. The only way to
stop the presentation is to use the terminal to kill the process.
It does not matter if you use a single screen or a two screen set-up.
Also note:- Keyboard controls stop working during playback i.e. Esc, Right
Arrow, Left Arrow.
Note that this only affects Linux distros with KDE/QT based desktops.
Steps to Reproduce:
1. Create, or download, an MP4 video with subtitles
2. Create an empty simple, two slide, presentation.
3. Add simple text title to first slide.
4. Add video file to second slide.
5. Save Impress file.
6. Play presentation, with or without a second screen, with presenter console
option selected.
Actual Results:
When you get to slide 2, the presentation locks-up and you cannot end the
presentation using on-screen or keyboard controls.
Expected Results:
Play the video at full screen size.
For two screen set-ups, the video should play at full screen size on screen 2.
Note: I was unable to capture this behaviour using screen capture software so I
attempted to film it using my phone camera. The file is uploaded to this bug
report.
