GNOME Bugzilla – Bug 793834
Totem no longer plays MP4s, despite correct plugins installed
Last modified: 2018-02-26 12:03:01 UTC
Recently I tested several video players, and after uninstalling them I can no longer view MP4 videos using Totem. I definitely have the necessary gstreamer plugins installed, however Totem incorrectly reports "Required plugin could not be found". It is as if Totem can no longer detect my installed plugins. I'm on Ubuntu 16.04.4 LTS running Totem 3.18.1-1ubuntu4 I've posted a related question here: https://askubuntu.com/questions/1008762/how-can-i-restore-totems- ability-to-play-mp4-videos I filed a bug on Launchpad as well, which has more details: https://bugs.launchpad.net/ubuntu/+source/totem/+bug/1751578 Here is the Terminal output if I try opening a video using Totem from the command line: tom@desktop:~$ totem Desktop/VIDEO.mp4 ** Message: Missing plugin: gstreamer|1.0|totem|H.264 (Main Profile) decoder|decoder-video/x-h264, level=(string)3.1, profile=(string)main, max-input-size=(int)64271 (H.264 (Main Profile) decoder) /usr/lib/python3/dist-packages/sessioninstaller/core.py:47: PyGIWarning: Gst was imported without specifying a version first.

First try this: $ rm ~/.cache/gstreamer-1.0/registry* $ totem foo.mp4 If you're lucky, this fixes it. If not, please check this: $ dpkg -L gstreamer1.0-libav | grep libgst $ gst-inspect-1.0 /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstav.so and see if it outputs anything, esp. any warnings. Also: $ ldd -r /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstav.so
rm ~/.cache/gstreamer-1.0/registry* did not resolve the issue. Output of dpkg -L gstreamer1.0-libav | grep libgst: /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstlibav.so Output of gst-inspect-1.0 /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstav.so: No such element or plugin '/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstav.so' Output of ldd -r /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstav.so: ldd: /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstav.so: No such file or directory

That looks like a packaging bug/problem to me.
> That looks like a packaging bug/problem to me. I'm afraid I do not understand what that means, and I am no closer to restoring Totem's ability to play my MP4 videos. Is there any additional troubleshooting I can try, or some new information I can add to the Launchpad bug report (I think that covers packaging?), so that I can resolve this issue?

Some libraries that the gst-libav package relies on are missing. Try reinstall the package, and if it doesn't work, file a bug against your distribution (or the repository where you got this version of gst-libav), there's nothing else we can help with.
OK, thanks for reviewing the bug report. I've filed a new bug at https://bugs.launchpad.net/ubuntu/+source/gst-libav1.0/+bug/1751769
