VideoLAN downloads the list of channels of 'Icecast Radio Directory' from http://dir.xiph.org/yp.xml
If this xml file contains entries with blank <listen_url> field, VideoLAN stops processing further channels.

Code: Select all

<entry><server_name>HearMe - Smooth Jazz</server_name><server_type>audio/mpeg</server_type><bitrate>128</bitrate><samplerate>44100</samplerate><channels>2</channels><listen_url></listen_url><current_song></current_song><genre>Jazz</genre></entry>

I downloaded manually the xml file and removed entries with blank (void) <listen_url></listen_url>.
Then I "deceived" VideoLAN to download my local edited xml.
Added to C:\Windows\System32\drivers\etc\hosts file: 127.0.0.1 dir.xiph.org
Created a local web server with PHP

Code: Select all

php -S localhost:80

This way, accessing 'Icecast Radio Directory' fetched and parsed the edited xml. Finally I created a Playlist with the channels I like and saved the radio-playlist.xspf file.

Or Icecast produces a xml with no blanks URLs, or VideoLAN learns to filter out those entries.

Please open Tools -> Messages (set Verbosity to 2) before you start the Icecast directory, and then paste the full resulting log here or on Pastebin.com if it's too long.

Then create a new ticket on the VLC Trac with the links to your log and to this thread:
https://trac.videolan.org/vlc/

I don't have time to comply with the VLC bug tracker reporting instructions. The debug log says:

Code: Select all

main debug: adding: Online Radio FM
lua error: Error while running script C:\Program Files\VideoLAN\VLC\lua\sd\icecast.luac, function main(): ...tras/package/win32/../../../share/lua/sd/icecast.lua:59: attempt to concatenate field '?' (a nil value)

That doesn't mean anything. I already found the internal problem: the xml parser stops when it finds a void field (that's what "nil value") means.

I appreciate what you've figured out there, but this a non-solution for the average user.

Lotesdelere - I have done as you instructed.

Issue quite easy to fix in the original icecast plugin:

For average vlc user:

Copy the code above to a new file, name it icecast-new.lua
Go to vlc install dir, then to lua/sd
Remove the original icecast.luac file
Add the icecast-new.lua file
Run vlc and enjoy

yaaaaaaaaaay, nice one , thank you for engineering and sharing that fix.
very average user here needed to do a bit of extra fiddling to find the file on mac :

the location of plugin on my mac was /Applications/VLC.app//Contents/MacOS/share/lua/sd/
in terminal, using sudo su we we copied the icecast.luac to icecast.luacold , deleted the original icecast.luac and used vi to create a new icecast.luac and then pasted the script above, saved, restarted vlc , all good!

Any chance of fixing this bug? Would be wonderful for those of us that are less technically literate - and much appreciated.

At the moment I cannot devote the time I would need to fix this bug. But I can assure anybody if you following the instrutions like we used to when we were young and just learning things, it will make sense. I am not a dev, and I anticipate taking a few wrong turns along the way.

And I'm going to risk being flamed. And I can tell you it this upsets you, grow up and stop complaining! The guys who developed VLC and do the work of maintaining it are not American. They do not react to being yelled at when and enduser tries a solution to a problem and it doesn't magically disappear. It sometimes requires more concentration and focus than you are used to using to fix a problem.

I had a situation with VLC a few years ago and I could not figure out how to fix it. I actually wrote to Jean-Baptiste (forgive me if I have your name wrong). I very politely explained that I'd failed using every solution I could think of. And if he could offer at least part of a solution I could appreciate it. He was very gracious in his reply. I never used that privilege again, but the point is, it you're going to act like an infant who has thrown your toys out of your pram, chances are you're going to be treated like one.

Excellent script, but I would recommend users to simply use it to create a new icecast.luac file instead of calling it something else and then use it to overwrite the existing one. I've posted instructions in this thread on how to do that. https://forum.videolan.org/viewtopic.ph ... 77#p522477

My post also includes before and after images which might be useful to peeps.
