Sample slide (PPTX) with video

Here we have a slide with a video playing (in an infinite loop) in the
background and some elements in the forefront.

Impress does not show these elements while the video plays nor after,
though it does show them in edit mode.

Version: 7.5.0.0.alpha0+ / LibreOffice Community

(Similarly for 6.4 - 7.3 I tested.)

Screenshot with PowerPoint in presentation mode

Comment 2 Aron Budea 2022-07-26 04:51:52 UTC

Confirmed using LO 7.5.0.0.alpha0+ (28daee8a3252e03a67484dc8d3dd26fd73af4826) / Ubuntu.
In earlier versions, eg. 4.x the video doesn't even play, probably due to some codec or multimedia lib issue. We can probably assume this was never okay.

Alternate, more complex, sample document (PPTX)

I wonder whether / believe that this, somewhat more complex, sample
document with two slides including a background video is about the
same issue - if possibly from a slightly different angle.

Still reproducible in

Version: 7.6.0.0.alpha1+ (X86_64) / LibreOffice Community

Comment 5 Tex2002ans 2024-03-26 20:51:07 UTC

Still an issue in:

I have 2 monitors, so when I pressed F5:

- 1st screen had presentation playing.
- 2nd screen had "Current Slide" + "Next Slide" thumbnails playing.

- - -

In attachment 181397 [details] (comment 0):

Both screens acted different:

- 1st = only background video playing
- 2nd = background video playing + constant white screen flashing of "Dev->QA->Prod"

- - -

In attachment 181501 [details] (comment 3):

Both screens were the same:

- Background video was playing.
- Could see animations moving/playing above the video.
- Constant black rectangle flashing.

- - -

So both attachments were still busted, but in slightly different ways.

Seems like there's constant flickering between the background (video) + foreground layers.
