MP4 missing codecs prompted for, but already installed. Ubuntu 22.04

[PowellDean]

Just installed VokoscreenNG-3.4 beta. Attempting a screen capture session saving to .mp4. Vokoscreen will not allow MP4 capture, prompting to install missing codecs (example gstreamer-base). This and all other packages are already installed: sudo apt install gstreamer1.0-plugins-base [sudo] password for : Reading package lists... Done Building dependency tree... Done Reading state information... Done gstreamer1.0-plugins-base is already the newest version (1.20.1-1). 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I recently upgraded from Ubuntu 20.04 (Vokoscreen capture to MP4 was working on this release) to Ubuntu 22.04 LTS (Jammy).

All codecs are installed and configured. I am easily able to play back .mp4 videos using VLC player.

Please advise.

This and all other packages are already installed:

Two packages are missing. gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly

[PowellDean]

sudo apt install gstreamer1.0-plugins-bad Reading package lists... Done Building dependency tree... Done Reading state information... Done gstreamer1.0-plugins-bad is already the newest version (1.20.3-0ubuntu1).

sudo apt install gstreamer1.0-plugins-ugly Reading package lists... Done Building dependency tree... Done Reading state information... Done gstreamer1.0-plugins-ugly is already the newest version (1.20.1-1).

I'm still getting the same error. It appears that both -bad and -ugly packages are already installed and at the latest version. These packages were installed in Ubuntu 20.04. A few weeks ago, I was upgraded to Ubuntu 22.04, but I'm not sure if the packages in question were upgraded as well at that time, or if they were left in place. Is it possible the versions are newer than Vokoscreen currently supports? Or perhaps the upgrade to 22.04 caused an issue. Would purging and reinstalling the packages in question be in order?

Thanks!

The user-friendly debugging module is finally finished and can now be used by you for the first time. See image. Beta 06, which contains this function, is available for Linux. https://linuxecke.volkoh.de/vokoscreen/vokoscreen-download.html Example: Step 1: Start vokoscreen Step 2: Switch to the fourth tab in the top bar Step 3: Enable GStreamer DebugLevel Step 4: Set the slider to value 2 Step 5: Close vokoscreen Step 6: Start vokoscreen Step 7: Switch to the fourth tab in the top bar Step 8: Click on the Folders button Step 9: Put the file GST-Debuglevel-2.txt here

[PowellDean]

GST-Debuglevel-2.txt

[vkohaupt]

There's nothing useful in there. Please create the same with level 1, 3 and 4.

[PowellDean]

GST-Debuglevel-4.txt GST-Debuglevel-3.txt GST-Debuglevel-2.txt GST-Debuglevel-1.txt

I recreated the -2, just in case

[PowellDean]

For the -4, I switched the codec to mkv, then closed vokoscreen. Then I opened it up again, switched logging to -4, then chose the mp4 codec so the error window discussed earlier would pop up. Hopefully that will give you something more to go on.

Thanks!

[vkohaupt]

No abnormalities here either. Then we continue with level 5 and 6

[PowellDean]

GST-Debuglevel-6.txt GST-Debuglevel-5.txt GST-Debuglevel-7.txt

Including level 7 as well, just in case. Thank you!

[vkohaupt]

Analysis

GST-Debuglevel-6.txt Line 34006: gst_element_factory_find: no such element factory "openh264enc" and Line 34007: gst_element_factory_find: no such element factory "x264enc"

These two elements are included in packages gstreamer1.0-plugins-bad and gstreamer1.0-plugins-ugly

Install are both packages, but GStreamer can not find the elements openh264enc and x264enc. The element openh264enc is in the library libgstopenh264.so Line 2524: read strings for name='libgstopenh264.so' Line 2524: desc.description='Plugin for blacklisted file' and the element x264enc is in the library libgstx264.so Line 262: read strings for name='libgstx264.so' Line 263: desc.description='Plugin for blacklisted file'

In the further course of line 2524 and line 263 you can see that the plugin libgstopenh264.so and libgstx264.so are loaded, but are ignored by Gstreamer because they are on the blacklist.

Control

Open a terminal and enter the following and you see all blacklisted files. gst-inspect-1.0 -b

Troubleshooting

We can now two things. First: Delete the file "registry.x86_64.bin" in the hidden folder ~/.cache/gstreamer-1.0 Start "gst-inspect-1.0 -b" in a terminal. If the files libgstopenh264.so and libgstx264.so further more in the blacklist then go to second.

Second: Purge gstreamer1.0-plugins-bad and gstreamer1.0-plugins-ugly completely from the system also from the cache of the package manager. Delete the file "registry.x86_64.bin" in the hidden folder ~/.cache/gstreamer-1.0 Start "gst-inspect-1.0 -b" in a terminal for control.

[PowellDean]

Thank you very much. Running the first step as listed above worked, and I can now choose mp4 as a target file format. This issue can be closed.
