Missing Video Codecs

[Angell1993]

I've run into an issue with embedded videos in PowerPoints, that says Missing Video Codec for embedded videos..

And there is no information I can find on which Video Codecs are used in FreeOffice Presentations under Linux, I do use Arch Linux..

It's a little hard to install the needed codecs if they are not listed anywhere, that's visible..

Normally ffmpeg, gstreamer, mplayer, mpv even vlc should be enough for most apps under linux for video playback..

Take a look at https://wiki.archlinux.org/title/Codecs ... deo_codecs

Installing vlc, mplayer and/or mpv wont solve the problem.

When you use Arch linux you must do things the arch linux way.

FreeOffice is the only app I use that has this issue, I can play any media file as embedded in my own app just by having vlc installed from the package manager, and I also use ffmpeg, gstreamer, mplayer, mpv as well as all the these packages..

So you tell me what is missing to playback embedded video:
Type: MCI Movie
File: [Embedded] - 35983kB
Exported as media1.wmv.. Exported it plays fine in vlc, mplayer, ffplay, mpv, xine, Parole..

ffmpeg give this info for video codec:
Stream #0:0(dan): Video: wmv3 (Main) (WMV3 / 0x33564D57), yuv420p, 1280x720, 8192 kb/s, 25 fps, 25 tbr, 1k tbn

Plays fine on the Windows app, but the Linux app won't play it keeps saying "Unable to play video (Properly missing codec)"..

I found the issue, FreeOffice is using the gstreamer engine, it was the last one that didn't work in the beginning until I found the required packages..

You do not have the wmv codec installed. The error is right there in what you share. Check you have libavcodec and gstreamer good, band and ugly codecs installed. This should solve the issue.

VLC can play this file because it has its own video codecs. Same foes for mpv.

libavcodec comes with ffmpeg..
mplayer, mpv, even vlc is based on ffmpeg so they might all share the libavcodec..

gstreamer require these addons to work with wmv codec:
gst-plugins-ugly
gst-libav

Although I did end up narrowing down the issue, by eliminating ffmpeg, mplayer, mpv, vlc and xine before I found the issue with gstreamer..
Is gstreamer even listed anywhere as the default media engine in FreeOffice on Linux??

[lgsl]

Most, if not all, Desktops relies on gstreamer this days so is a "given", I suppose.

Now what is uncommon this days is the use of wmv. To be honest I would simply convert the video to a more standard/better supported file format and be done with it.

[Angell1993]

wmv is the embedded format in powerpoint, so not really a choice, seeing it's an mp4 before adding it to powerpoint..

As for gtreamer I've never had any issues before, properly because of wmv being a weird format to begin with..
