GStreamer; Unable to play

[NikEyX]

Hi, I have a problem with the theme. Not sure what changed, but it doesn't seem to play the videos anymore on my Arch installation. Looking at journalctl it seemed that this is a resolve error, probably due to the fact that the internet is not connected yet when sddm runs:

Oct 17 13:08:28 local sddm-greeter[886]: Error: "Could not resolve server name."
Oct 17 13:08:28 local sddm-greeter[886]: Error: "Could not resolve server name."
Oct 17 13:08:28 local sddm-greeter[886]: Error: "Could not resolve server name."
Oct 17 13:08:28 local sddm-greeter[886]: GStreamer; Unable to pause - "http://a1.v2.phobos.apple.com.edgesuite.net/us/r1000/000/Features/atv/AutumnResources/videos/b5-2.mov"

....

So instead I downloaded all the videos and am trying to play them offline, but this now fails in a different way:

Oct 17 12:47:04 local sddm-greeter[885]: GStreamer; Unable to play - "file:///home/xxx/videos/aerial-videos/DB_D008_C010_2K_SDR_HEVC.mov"

Oct 17 12:47:04 local sddm-greeter[885]: Error: "Could not open file \"/home/xxx/videos/aerial-videos/DB_D001_C001_2K_SDR_HEVC.mov\" for reading."

Oct 17 12:47:04 local sddm-greeter[885]: Error: "Could not open file \"/home/xxx/videos/aerial-videos/b4-1.mov\" for reading."
Oct 17 12:47:04 local sddm-greeter[885]: GStreamer; Unable to pause - "file:///home/xxx/videos/aerial-videos/b7-2.mov"
...

...Which is odd, because the file paths are correct and clicking them opens the media player and plays the video.
Running sddm-greeter --test-mode --theme /usr/share/sddm/themes/aerial-sddm-theme/ also works flawlessly and shows the videos. So this only happens at startup, not while testing. This makes it hard to debug because I have to restart my PC every time.

Do you have any idea what could cause this?

Hi there,
I haven't used this in a while but it doesn't work for me either on Kubuntu...
I have no clue what might be causing this since it works in testing mode.
When did it stopped working for you ? Could you retrace it back to some package update or something ?

[NikEyX]

It stopped working about 11 months ago - but cannot tell you the exact date. A shame this doesn't work anymore, it was such a good greeter!

[3ximus]

Hum, sddm did get an update about 11 months ago
https://github.com/sddm/sddm/releases
Could be related to that... I might test it later if rolling back to a previous sddm version fixes the issue. If you do that too please let me know how it goes for you

[NikEyX]

I downgraded to 0.18.0 of SDDM and rebooted - that didn't fix it. It's probably some change in QT or a bigger encompassing package. Too tedious to downgrade every single one of them. Really a shame.

Oh well... That sucks.
Yeah idk if I have the patience to see what can be done...
Thanks for checking anyway
Cheers

[3ximus]

There are still people starring this repo though, so it must be working for them...

[NikEyX]

ok I fixed it on my end by copying all the videos manually into the theme folder (I made a new sub-folder called videos) and created a new playlist that would reference these videos. Now it works. It doesn't work if the videos are on a different drive. My guess is that's either sudo related, or load-order dependent (my original drive might not be mounted / available at the point in time when sddm is trying to load the video).

Note that this still doesn't fix the outright "loading from web" - that's still broken, so this is just a temp fix.

Ok thanks for letting me know 👍

Hi,
I've encountered same issue when porting this package into Guix.

In strace output I noticed some qml files are missing Qt.qml (line 5420) and Date.qml (line 6357).

When I attempted to use the patch below I got the "TV color strips" instead of the background image. Though that is caused probably by the videotestsrc.

Yeah, I haven't got a clue about this. I've tried it today and it seems to be working. I really don't know what might be the issue...

[phodina]

@3ximus which distro and sddm version do you use?

[3ximus]

I have Ubuntu with Plasma (Kubuntu) and sddm version 0.19 from Ubuntu package manager

Hi sddmers, I also unable to launch the theme. it looks like the post having same problem so I added it.

Is this error?? the window showing video though, not launching at startup. Sddm just showing default one. I am using wayfire wayland. How everyone makes this working?
