 # TODO:
 
+- [ ] test pipeline:
+
+  - I get the following error when running the tests in a github workflow using
+    ubuntu-latest:
+    ```bash
+    qt.multimedia.player: Warning: "No decoder available for type 'video/quicktime, variant=(string)iso'."
+    ```
+    I tried the following:
+  - Set the QT_MEDIA_BACKEND to ffmpeg as the website suggests this is more
+    stable.
+  - Install all qt6 multimedia packages I could find.
+
+  Interesting is that I get the same error when when I set the QT_MEDIA_BACKEND
+  to gstreamer on my Arch Linux machine. I was able to fix this partially by
+  installing many gstreamer packages. However, I want ffmpeg so switching to
+  gstreamer is not an option (it is also not recommended by the qt website).
