Dear bordfeldt,

To make sure we're focusing on the bugs that affect our users today,
LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed
bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this
bug report. During that time, it's possible that the bug has been fixed, or the
details of the problem have changed. We'd really appreciate your help in
getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice
from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information
from Help - About LibreOffice.

If the bug is NOT present, please set the bug's Status field to
RESOLVED-WORKSFORME and leave a comment that includes the information from Help
- About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular
meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a
REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your
bug pertains to a feature added after 3.3) from
https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat:

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team

Still having the same issue as the other posters in v6.4.6.2. Audio  plays, but
video image does not. I tried insalling k-lite and LAVfilters. Is there a way
to change the setting to enable vlc support on windows? I read about a google
summer of code for that, but I can't seem to find any info on how to use it.

As mentioned in 62408 comment 39: 'LO only supports playback through DirectShow
filters, while "Windows Media Player supports the Media Foundation framework
besides DirectShow".'

Yes i'm aware of the install center which installs the codecs to the system.

All the codec packs bundle LAV Filters.

Tested the file on WMP, and it shows it just like LO, gray frame during
playback. So i tested it in Zoomplayer again and noticed the same gray frame,
but it appears for a split second at the beginning, so it i possible that the
sample file is corrupted at the beginning, as the mpeg-2 sample files here[1]
all play file in WMP and LO. One difference that i did see in MediaInfo is that
attachment 130234 is using the mpeg-ps container.

Regardless, if it plays in Windows Media Player it should play in LibreOffice.
That test tells us that Windows knows how to play this file.
On my system it plays in WMP and in LO.
If this is not a valid test, I would like to know.
I would expect your WMP to not play the file.
If it does, that tells us something useful.

FYI, Zoomplayer installs many of the same all-in-one codec packages that are
included in VLC and other players. 
If I remember correctly, all-in-one codec packages like FFDShow, etc. do not
work with WMP, and similarly with Windows OS itself.
It will take about 1 minute.
Please test with Windows Media Player.

OK, I will upload it and post a link.
If your WMP works after that it tells us something.
If your LO works after that it tells us something.

Yes this is off-topic, but the short answer is, codec patents. You can get a
clearer answer by asking Michael Stahl in the dev IRC channel, which i recently
did.

Actually, a VLC backend exists, but it is incomplete and abandoned. It was the
result of GSoC 2013: https://wiki.documentfoundation.org/Development/GSoC/2013
Over the years I have tried to recruit new developers to work on a new
implementation based on VLC's new official C++ bindings library:
https://code.videolan.org/videolan/libvlcpp

I encourage anyone interested in this feature to continue recruiting people to
re-do this, targeting the upcoming VLC 3.0.

I'm following the Media Playback issues a bit. It's probably a bit off topic
and asked before, but anyway... I'm wondering, why is LibreOffice using the
native (system) media-player/codecs anyway? Why not embed a cross platform
directly media-player into LibreOffice (for example VideoLAN; MPV). Or - a bit
less drastic - make it possible to use a specific backend if available: for
example the VideoLAN (it can be pushed as a separate install).   

Some reasons:
*The audio/video format support is now inconsistent; system depended. Creating
a working presentation on Linux doesn't guarantee a working presentation on
Windows. Or even with the same system environment   
*The out-of-box experience for the end user is bad. You need to install
separate codecs (especially on Windows). And codec pack which can change the
default filters at any time. Multiple media players are bundling there own
codecs (VideLAN; Potplayer); there must be a reason for that 
* Maintaining different backends on different system environments
(win/mac/linux) with different quirks look like a lot of work (and harder to
test).
*LibreOffice should work on the 'core'. Media playback issues should be
addressed by a team (more) devoted to that. 
*Installing a codec-pack in business like environment will always be
problematic (and the default configuration doesn't guarantee a working
playback)

Only a though; there are probably good reason for the current situation.

Most media players dont bundle their own codecs, but yes if it did bundle its
own codecs, like VLC, then it wouldnt be relevant in this case, but Zoom media
player doesnt.

Didnt test with WMP as it doesnt solely rely on DirectShow to playback videos.

No dont have the MainConcept encoding app installed, but if you can point me to
where i could download it, i'd gladly test it.

... "a media player" ... ?

Which media player?
Many media players have their own built-in codecs.
DirectShow is not involved in that case.
So using many players to test is not going to give useful results.

I test with Windows Media Player (WMP).
WMP is going to use the same codecs and splitters available to the operating
system.
If it plays in WMP, it should play in LibreOffice.

Have you tested with Windows Media Player?


Also I would like to see if you installing the same MainConcept encoding app
that I have installed would solve the issue on your test system.
I can upload it somewhere (~65MB) if you would like to test.

Guess i should have been clearer about this in comment 14, KLite provides
ffmpeg/LAV codecs, including a MPEG-2 video decoder which is able to playback
the video of attachment 130234 just fine in a media player, so not sure why LO
is having a problem playing it back.

Microsoft has a MPEG-2 video decoder according to the link below, but dont know
how you'd get it

--- Comment #15 from LibreTraining  ---

It appears that a standard Windows installation does not support MPG-2.

"... Because Microsoft Windows operating systems provide only an MPEG-1 video
decoder, Windows Media Player cannot play MPEG-2 program streams without an
additional MPEG-2 video decoder ... "

Info found here:
https://support.microsoft.com/en-us/help/316992/file-types-supported-by-windows-media-player


I also found why it does work on my Windows 7 x64 machine.
Using the free GSpot Codec Information Appliance application I determined that
playback was using a MainConcept codec which is installed with their encoding
application.
It could also be played using a Ulead codec installed with my free Toshiba DVD
app.


So regarding MPEG-2 Video playback in Impress on Windows:
- Default Windows installations will not play MPG-2 video streams
- DVD applications will install a codec which will work 
- Microsoft has (or had) a DVD decoder pack which will install the needed codec


Note: I assume you should use the free GSpot Codec Information Appliance
application to confirm that you have no working decoder path available for that
video and that this is the issue.
And then install a DVD application or an advanced encoding application to see
if it starts working as expected.

Also, GSpot can be used to see which codecs are currently installed on your
system.
