After some rough investigations, there are three different issues. The first issue: the v4l2 video device is not listed from `pw-dump`, but I can make it listed after executing `systemctl --user restart pipewire`. So it could be related to some initialization problem within the pipewire infrastructure.
The second issue is a stream error that makes it unable to play camera stream. https://paste.ubuntu.com/p/MYPXTs3K39/ The third issue is only observed by my own USB camera device so far that even there is no problem to initial the device on snapshot, but it can not fetch the camera stream to show or to record. I am not sure if we will encounter the third issue after we solved the previous two issues. https://paste.ubuntu.com/p/dcW4f6ykzs/ FYI, https://gitlab.gnome.org/GNOME/snapshot/-/blob/main/TROUBLESHOOTING.md ** Also affects: oem-priority Importance: Undecided Status: New ** Summary changed: - Snapshot failed to work on mipi camera + Snapshot failed to work on Intel MIPI camera ** Changed in: oem-priority Status: New => Confirmed ** Changed in: gnome-snapshot (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-snapshot in Ubuntu. https://bugs.launchpad.net/bugs/2076315 Title: Snapshot failed to work on Intel MIPI camera Status in OEM Priority Project: Confirmed Status in gnome-snapshot package in Ubuntu: Confirmed Bug description: Currently mipi camera failed to work on snapshot app on Ubuntu 24.04, hope this issue can be fixed.
