RadialSlider

[kalyx]

I can't get the radial slider to work. The skin will not load with the following:

Code: Select all

<Bitmap id="bmpRadial" file="radial.png" alphacolor="#FF0000"/> <RadialSlider value="volume" x="10" y="180" sequence="bmpRadial" nbimages="5" minangle="0" maxangle="270" lefttop="leftbottom" rightbottom="leftbottom"/>

What does the log say ? (vlc --verbose 2). If there is a syntax error or something wrong, this log will tell you

[kalyx]

I'm on windows XP.
If I start vlc from a console like
vlc --verbose 2
I don't see any log.

[erwan10]

vlc -I skins --verbose 2 --skins2-last your_skins.vlt 1> c:\\tmp\\log 2>&1

[kalyx]

The logs for the linear or radial slider are identical except that with the radial the log ends at this point:

Code: Select all

[00e1748c] main access debug: using access module "access_file" [00e1748c] main access debug: TIMER module_need() : 3.688 ms - Total 3.688 ms / 1 intvls (Avg 3.688 ms) [00e18024] main stream debug: Using AStream*Stream [00e18024] main stream debug: pre buffering [00e18024] main stream debug: received first data after 0 ms [00e18024] main stream debug: pre-buffering done 1024 bytes in 0s - 20833 kbytes/s [00e0a7b4] skins2 interface: skin: xxx author: xxx

Here is the command I used:

Code: Select all

vlc -I skins --verbose 2 --skins2-last c:\\XXX.vlt 1> c:\\log.txt 2>&1

BTW, Do you know of any skins that use a radial slider?

[erwan10]

It seems the RadialSlider tag has not been used a lot. A search on the whole set of skins available on http://www.videolan.org/vlc/skins.php gives no such tag.

As for your skin, you should have more logs. Can you paste your .vlt file somewhere so that I can have a look at it.

It's just a simple test skin. As configured below it will run. But if you comment out the Slider and uncomment the RadialSlider, it doesn't work.

BTW, I'm running version 1.0.5 of vlc.

Obviously, this skin feature (RadialSlider) was never finished. I found several bugs that prevented it from working at all.
You don't have more logs, because it crashed

I'm about to commit fixes. It will be available in a soon-to-come update of vlc1.1

Thanks for looking into it. I'll try it again after the next update.

[erwan10]

A last thing, the documentation is not that clear about what minangle and maxangle means.

The vlc trigonometry goes like this :
- angle = 0 is the Y-axis towards the bottom
- it goes clockwise

For your radial.png, you should give the following : minangle="45.0'' maxangle="315.0" for the best visual result.

And if you wish to test it, nightly builds are usually available (http://nightlies.videolan.org/build/), but the server seems down just right now.

Thanks for the info about the angles. I was just guessing since, as you said, the documentation was unclear. I'll try a nightly build when the server is back up. Thanks again.
