Online radio commercial filter

valentas · Postby **valentas** » 27 Jul 2012 13:32

Hi,

I would like to have a filter that checks the online radio song information (VLC displays it in the status bar) and silents it down based on some criteria (for example the commercials).

What is the easiest way to do it (I can write the code myself)?

Thanks,
Valentas

The easiest is probably a lua extension for that.
You can do an interface too.

I am posting my whole script, because I find it incredibly useful for myself. Sorry I don't have time to make it usable for generic audience: you would need
to add some interface to select which keywords in the title refer to an advertisement. Currently, to adapt to your own radio station, change keywords like "REKLAMA" in the script to match whatever you see during an advertisement.

On Linux this has to be stored in a new file ~/.local/share/vlc/lua/extensions/mute_down_ads.lua. To activate the script you have to check the box from the VLC right-click menu.
