How can I get the MPEG-TS support for GStreamer?

Trying to play a MPEG-TS stream with gst-play in a 22.04 box, I get:

Missing decoder: MPEG-2 Transport Stream (video/mpegts, systemstream=(boolean)true, packetsize=(int)188)

while it works fine in another one (also with 22.04).

Where it works, I get:

$ gst-inspect-1.0 mpegtsdemux
Plugin Details:
  Name                     mpegtsdemux
  Description              MPEG TS demuxer
  Filename                 /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstmpegtsdemux.so
  Version                  1.20.3

  Source module            gst-plugins-bad
  Source release date      2022-06-15
  Binary package           GStreamer Bad Plugins (Ubuntu)
  Origin URL               https://launchpad.net/distros/ubuntu/+source/gst-plugins-bad1.0

  tsdemux: MPEG transport stream demuxer
  tsparse: MPEG transport stream parser

  2 features:
  +-- 2 elements

while where it doesn't:

$ gst-inspect-1.0 mpegtsdemux
No such element or plugin 'mpegtsdemux'

But as far as I can see, the plugin should be available here too. The file is there

$ls -l /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstmpegtsdemux.so
-rw-r--r-- 1 root root 197488 Jun 29  2022 /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstmpegtsdemux.so

and the "bad" plugins package in installed:

$ apt list gstreamer1.0-plugins-bad
Listing... Done
gstreamer1.0-plugins-bad/jammy-updates,now 1.20.3-0ubuntu1 amd64 [installed,automatic]
gstreamer1.0-plugins-bad/jammy-updates 1.20.3-0ubuntu1 i386

What could be missing? How can I refresh the plugin database/registry/whatever? I tried apt-get install --reinstall gstreamer1.0-plugins-bad with no apparent effect.

It looks like the registry is cached in `~/.cache/gstreamer-1.0/registry.x86_64.bin`, removing it worked, but maybe there's a better way to refresh it...

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
