Nemo-preview not playing h264 video in LM 21 about nemo-extensions HOT 11 OPEN

It looks like you never installed the Mint codecs package, which would have brought this in - it was also a checkbox during installation.

Check the menu for 'Multimedia Codecs' or run apt install mint-meta-codecs

from nemo-extensions.

mint-meta-codecs package was installed (and not) (tested both cases)

from nemo-extensions.

Upd: aptitude install mint-meta-codecs: not working
aptitude install libopenh264-cisco6: working
(Aptitude suggests only with deletion of mint-meta-codecs when installing libopenh264-cisco6 and deletion of libopenh264-cisco6 when installing mint-meta-codecs)
And xplayer cannot play the file without libopenh264-cisco6
Maybe there is a bug which doesn't allow nemo preview work with libopenh264-6 (no cisco)

from nemo-extensions.

Just rebooted live, updated everything except kernel, libreoffice, firmware and microcode, relaunched session (log out and log in), did the experiment, aptitude install mint-meta-codecs -> not working
aptitude install libopenh264-cisco6 (agreeing to remove meta-codecs) -> working preview

from nemo-extensions.

Weird - works ok here:

are all of those installed? ^ These types of packages frequently have strange dependencies, or will declare they provide package X even though package X may also exists separately, so it's entirely possible some combination of packages is causing this.

Btw, I tested the first sample video from here: https://www.h264info.com/clips.html

from nemo-extensions.

gstreamer1.0-plugins-bad provides the h264 codec support.

from nemo-extensions.

I tried it, (was installed with mint-meta-codecs)

from nemo-extensions.

Try removing the gstreamer1.0 vaapi plugin to see it that fixes the gstreamer crash

from nemo-extensions.

Try removing the gstreamer1.0 vaapi plugin to see it that fixes the gstreamer crash

force removed gstreamer1.0-vaapi, it works

from nemo-extensions.

Did i understand that correct: it' not nemo-preview's bug but gstreamer-vaapi's?
And not LM's problem, but Ubuntu's?
