After upgrading to 6.2.8 to 6.3.5 I found that .avi videos inserted in Impress slides did not render successfully in slide show mode. There was a brief flash of what was probably the first frame, then the display reverted to the slide background image. The problem arose both when the video was linked and when it was embedded in the slide. I discovered this when trying to build a new presentation with 6.3.5 but found the same symptoms when I tried to display an old presentation (several different video clips) made with 6.2.8 which had displayed successfully under 6.2.8. I only tried .avi video, so can't say how other formats behave.
I have now uninstalled 6.3.5 and re-installed 6.2.8. I note that the video in the new presentation I had built with 6.3.5 displays successfuly in 6.2.8, suggesting that this is a rendering problem.
I am running 64 bit Windows 10 Home on a 3 Ghz G3220 Pentium with $GB RAM.
Steps to Reproduce:
1.Insert an avi video in an Impress slide
2.Go to slide show mode to start at the previous slide
3.Advance to the slide containing the video (mouse click)
The video is not rendered and the slide background image is displayed
The video should have been rendered
User Profile Reset: No
Rendered the video
cannot confirm here with LO 22.214.171.124 on Linux, VCL kf5, de-de
I can confirm the bug in 126.96.36.199 and 188.8.131.52, in 184.108.40.206 it is still working. I used the same file in all three tests, which was created using 220.127.116.11, so the problem seems not to be raised when the video is inserted.
By the way: the video did run directly after inserting it in 18.104.22.168, but after saving, closing and reopening it didn't work any longer.
All tested with Windows 10, so it might be depending on gthe operating system.
When right-clicking on the video while the presentation is running and there ending the presentation, the video did run correctly when the presentation was run again, also for the next runs tried.
Bug makes sense only if we have reproducible steps.
1. Please attach sample ODP.
2. Try both with/without OpenGL (there up to LO 6.4) or Skia (from 7.0) in Tools-Options-View
3. Please try daily master from https://dev-builds.libreoffice.org/daily/master/current.html
I think Colin's report describes how to reproduce the problem, but to avoid delay I will add a test presentation Test_avi_does_not_play.odp.
I tested with LibO 22.214.171.124, 126.96.36.199 and 188.8.131.52; I didn't install a daily build because I don't know how to handle that without replacing my working installation, I use Separate Install GUI for a parallel installation, and there the daily builds seem not to be provided.
The results are principally as described, but Timur's guess (?) regarding OpenGL resp. Skia is right:
184.108.40.206: the video plays with and without OpenGL
220.127.116.11: the video plays with OpenGL activated, without it only the sound is playing, the rectangle for the video remains black.
18.104.22.168: same behaviour a 22.214.171.124, if Skia is activated or not instead of OpenGL.
Since OpenGL produced some problems, as I have read many times, many people will have deactivated it. As regards Skia I have no experience and no information, but nevertheless the video should be playing even without Skia, I think.

Thanks. Those who test many bugs need clear steps, no time to start from scratch.
More, I tried with avi but it worked, so I wasn't sure if it's about my computer or sample. So, sample is always needed.

They are there, daily master like "master x86_64 (TB77-TDF)". I also use it in Windows that way. Mine SI-GUI is 126.96.36.199.

Colin didn't write if OpenGL or not/GDI, please test, also test master that installs separately to your working LO, if not using SI-GUI then from https://dev-builds.libreoffice.org/daily/master/current.html.
Gerhard explained well, meaning that on some systems/video cards current LO doesn't play with GDI (plays with OpenGL or Skia). Please test master to be sure.
Timur has no issue with LO 7.0 and master 7.1+ in Windows, video plays with Skia and without (that's GDI). Also no issue in Linux, bug is Windows so far.

This is a regression. Most useful in regression is bibisect.
But this one can be done only in Windows, and some who do bibisect in Windows do not reproduce it (I do it in Linux for all versions, no more space).
Meaning: Gerhard, you seem to be advanced Lo contributor, please see if you could set up Windows bibisect as in https://wiki.documentfoundation.org/QA/Bibisect.
Oliver, pleas test and write your video card... and see me praising Win bibisecters :)

Actually, this 131310 and bug 130524 look duplicates of Bug 128353 which is already bibisected.
