Didn't work on Ubuntu 20.04

[jalenzz]

Hello, uosc dit not work on my computer, other scripts can work well, but uosc not.

I install it follow the step in README, I think it right, but nothing happen, it dosen't display anything when I open an video.

What should I do?

[po5]

What is your mpv version? Did you set osc=no?

[jalenzz]

@po5 Yes, I set osc=no, When I open a video, there is nothing display, no osc, no uosc.

[jalenzz]

My mpv.conf

# required so that the 2 UIs don't fight each other
osc=no
# uosc provides its own seeking/volume indicators, so you also don't need this
osd-bar=no
# uosc will draw its own window controls if you disable window border
border=no

And mpv config directory

If it doesn't show anything, it might have crashed somehow. Do you see an error in the console?

[jalenzz]

Thanks, I try to use console.

I've made a PR that should fix it for you.

I've made a PR that should fix it for you.

thanks for that😆

[jalenzz]

@christoph-heinrich sorry, there is a new problem

[uosc] Lua error: /home/jalen/.config/mpv/scripts/uosc_shared/lib/utils.lua:520: attempt to call global 'thumbnail_render' (a nil value)

[tomasklaen]

There's no reference to thumbnail_render in uosc_shared/lib/utils.lua. What is going on here? o.O

[christoph-heinrich]

There is no reference to thumbnail_render in the whole project, nor can I find any place where something like it might be concatenated.

Let's make sure you're using all files from current master without any potential leftovers.
Can you please delete uosc.lua and uosc_shared/ and then download current master and use the files from that?

[christoph-heinrich]

@jalenzz I just realized you're using files from #353. Please use files from master branch only.

[jalenzz]

thanks, that's solved, but it still did't work, display nothing.

I directly git clone https://github.com/tomasklaen/uosc.git, but still have the problem #413 (comment)

[christoph-heinrich]

display nothing

What exactly do you mean with that?

If the video is not showing, that's not a problem with uosc anymore.
That could be a problem with your config, mpv, drivers...
A good first step is to try running mpv with --no-config and see if the problem still exists. If it doesn't then you'll need to find out which part of your config is causing the problem.

If you think you found a problem with mpv itself, or if you need help troubleshooting you should open an issue over in https://github.com/mpv-player/mpv/issues or ask in their IRC. In both cases you'll need to provide a log file created with --log-file=.

[jalenzz]

I'm sorry for my unclear description.
This video can be played normally, but the uosc didn't show.
I run with --log-file log.txt

[christoph-heinrich]

I don't see anything related to uosc_shared in there, so maybe it's failing to load that? According to your previous error message it must have been able to load that, so I don't know what's going on here.
Is your directory structure still like it was in #413 (comment)?

[jalenzz]

Yes, it's still like it was in #413 (comment)

[christoph-heinrich]

If it's not something with your configuration then I have no idea what could be the problem.

If you want to be 100% sure that your config is not the problem, I've made a minimal test configuration.
Simply unpack the folder inside somewhere and then run mpv --config-dir=<path to folder>/test-config.

[jalenzz]

I try that, but still, uosc didn't show 😭

I gave up, but sincerely thanks to you!
