https://sourceforge.net/projects/airtime/files/2.2.0-beta1/?

We are pleased to announce the beta for Airtime 2.2. The UI is incomplete at the moment - it will be now our main focus before the Release Candidate.

Some new features for the 2.2 release:

-Smart Playlists

-Webstream rebroadcasts

-Replaygain support

-FLAC + WAV support (AAC if you compile your own Liquidsoap)

-Huge performance increase on library import

-User ownership of files

-Stereo/mono streams

-Rescan watched folders button (useful for network drives where keeping in sync is more difficult)

-And much more

Please try out the new features and help us towards a bug-free release :)

BOW FAT FAT FAT... it's a year since I use Airtime and I dreamed about those features!
Keep up the good work!

Can you guys redirect me to a safe upgrading procedure from 2.1.3 using the beta file?

(and downgrade if things go bad..;)

@Guytrance: this version is not for use in production
anyway you have all installation informations here : http://www.sourcefabric.org/en/products/airtime_manuals/

did have a look at this release last night...

i have had just about 150 tracks in the watched media folders and stor-sub-folders.

so after recognizing a cpu-usage of up to 20% for liquidsoap-service, i let airtime spend the night with analyzing replaygain. but nothing really changed. still a high cpu-load without being able to display the "Library". It always stucks in "Processing".

So i thought about deleting the watched media folders and adding an empty one. but no changes at all.

Airtime-Liquidsoap Service is still using CPU about 20% but no Library accessible and adding a new track also fails.

should i just reset the track database in this case? and if yes, how to do that?

and another question of replaygain, because i got thousands of files with ReplayGain-Values in ID3Tags written with foobar in the ID3Tags "REPLAY_GAIN_TRACK_GAIN" and "TRACK_PEAK" or somewhat like that.

Does Airtime/Liquidsoap read and use this tags when available?

Does Airtime/Liquidsoap write ReplayGain-Infos as an id3tag or in its database?

I'm really overwhelmed of the new features and cannot wait to test more.

nice greetz, hoerich

sudo ~/airtime-2.2.0/install_minimal/airtime-install

Debian package of Airtime detected. Please use the debian package to upgrade.

Where to go from here?

FrancescoP

BTW, I'm still getting that utf8 decoding error and media monitor crash for the watched directory, and that trick of forcing the "replace" parameters (see here) is not working too anymore! :(

I don't exactly know which stream-types will be supported,
but for now I cannot get any BBC World Service Stream to run.
http://www.bbc.co.uk/worldservice/institutional/2009/10/091029_internetradiomobilelinks.shtml
This is essential for community radios like us. so it would be nice, if you consider this.

anyways, I thought of a second airtime-server only for re-broadcasting, which would give me the possibility to re-broadcast BBCWS via Line-In from Satellite-Source, since our Studio occupies the Line-In of the Airtime-Server. (since I guess it is not possible to run a second instance of airtime on the same machine) just a thought.

Martin Konecny

This is great! :)

One small bug and one idea:

bug: the airtime-check-system script reports that all services are down (FAILED), even if everything is running fine. The web interface reports running status OK but can not read uptime and CPU / memory usage. I've installed this beta on an Ubuntu 12.04, from which I have purged airtime 2.1.3, manually removed ad reinstalled monit/rabbitqm/liquidsoap, manually purged airtime database.

idea: Smart Block are great, but now I want more! ;) If I have a recurring show, I have to edit each show instance to insert the smart block, which is in that very moment expanded as a list of songs. Wouldn't be nice to be able to associate a smart block to all show instances with one click, and let Airtime expand them the day (or some hours) before the show executes?

Thank you, Airtime is becoming more and more amazing with every release!

What is the output of "sudo monit status" ? Also we will have lots of improvements to Smart Playlist post 2.2 release :)

I just looked into this, and we should be able to support the bbc .pls streams. The .asx ones will defn not be supported. Will post any updates on this here.

Reply to @Francesco+P.+Sileno:

Please post the logs as an attachment and we'll resolve this.

hoerich

1. which 3rd party app is used for ReplayGain analyzing?

2. if I try to change the background-color-style of a recurring show, it denies with the message: "Cannot schedule overlapping shows".

3. thanks for the good news about streaming BBC

Reply to @hoerich:

1) Utilities called "mp3gain", "vorbisgain" and "metaflac"

2) Nice catch! Created ticket here: http://dev.sourcefabric.org/browse/CC-4382

Please post the file /var/log/airtime/media-monitor/media-monitor.log as attachment, we will try to fix before next beta.

one more thing
when I'm try to repeat a show whit its content, content is not pasted. not really cool for the webstream (for example) or smart block

FrancescoP

Hi Martin!

Here they are, media-monitor.log and the whole airtime log directory, after a fresh start.

If you want, I can enable back your SSH access. It is the same machine you already checked. :)

Albert FR

@Martin+Konecny:copy/paste of contents from webstream and smart block are really mandatory.
Are they available in the final release ?

Guytrance · Post edited by Guytrance at 2012-09-10 10:56:32

How unstable this beta really is if i want to use it on a production server? (the smart playlists is extremely important feature) :(

is there any detailed guide on the smart playlists?

Albert FR

We need copy/paste entire show :D

Martin Konecny

Reply to @hoerich:

Liquidsoap service will always use about 20% CPU (it is not doing the Replay Gain calculations), because it is always streaming even if nothing is scheduled (it streams inaudible random noise so that clients do not disconnect if there is a gap in your schedule).

If you want to check whether your ReplayGain values were calculated, you can run the following command:

sudo -u postgres psql -c "select track_title, replay_gain from cc_files" airtime

For the next beta, we will make these values visible in the Library.

Does Airtime/Liquidsoap read and use this tags when available?

We use a third party tool to calculate the gain, and reading the documentation, this appears to be the case.

Does Airtime/Liquidsoap write ReplayGain-Infos as an id3tag or in its database?

We store the calculated values in the Airtime database to prevent modification of the original files.

Martin Konecny

Reply to @Guytrance:

You have a previous version of Airtime installed (which we do not recommend), and you cannot mix and match debian and tarball packages.

You can *completely* remove the old Airtime (Warning: Airtime database will be reset) , if you want to try this beta:

sudo apt-get purge airtime

Then try installing this tarball.

Ok, thanks for now, Martin! You're the Man!

When i try to schedule a show that is exactly after another one..(7-9,9-11) it says "Cannot schedule overlapping shows". even if i change the first show to start on 9:01...

Yep agree with Albert. Copy paste shows please.

I would not recommend this for production. You may not have any way to upgrade to the final release.

Hi Francesco it seems like you have encoding issues with your file system. Can you take a look at this thread http://forum.sourcefabric.org/discussion/14344/update-database-media-is-failed/p1 and tell me if it helps.

Denise Rigato

Reply to @Guytrance

Are you still able to recreate the overlapping show error message? If so, can you provide more details.

Albert FR

@Martin+Konecny: for your information, it's impossible to create webstream with the last snapshot from airtime

FrancescoP

@Rudy, Martin already pointed me to that discussion and I tryed that trick, see:

http://forum.sourcefabric.org/discussion/14321/force-reindex-of-media-files

However I'll try again, who knows. :)

riprovatamente,

Maybe you already knew, but:

root@microserver:~# airtime-import
Traceback (most recent call last):

AttributeError: 'module' object has no attribute 'api_client_factory'

Can anybody give a quick lowdown on what the new Smart Playlists feature is all about? Can't find any documentation on it - and I can't install the beta at this point.

Todd Fisher Wallin

Hey guys... I have a bug, but it might be an upstream debian issue.

Running on debian squeeze, I pulled an update for rabbitmq from the upstream debian repositories the night after installing the beta.

This caused the following symptoms:

1) 'Showbuilder' page would not render
2) login page worked
3) all other pages rendered but some with errors including the library page
4) airtime-check-system reported rabbitmq failed
5) monit.log wrote continuous errors until disk was full!
   -disk is only 10GB VM image and /srv/airtime/stor is an NFS mount
   -monit.log and monit.log.1 were 5.6GB combined

Restarting rabbitmq and monit did not solve problem. I had to do a complete removal of airtime, including /etc/airtime, and do a fresh full-install to fix. When I installed the beta I did a complete removal of the existing airtime install including /etc/airtime and /srv/airtime/stor

While things are now functioning ok with airtime and airtime-check-system reports all is well, there is still an issue. monit.log is still being filled with the following error...

[CDT Sep 17 08:16:27] error    : monit: Error reading pid from file '/var/run/rabbitmq.pid'

This is because the pid is no longer written to that file, but rather to /var/run/rabbitmq/pid

We have had other mission crit issues this past two weeks so I haven't had time to troubleshoot further and file a ticket.

Martin, Rudy, I've somehow solved the problem I had with filenames and UTF-8.

After some test, I realized that some file names were so messed up that even mvconv went puzzled - even if it was saying that they were renamed, in fact they weren't!

So after two runs I've been able to identify these bad files and move them away.

I still think that media-monitor should just skip this files insted of crashing, but thanks again for the tricks and sorry for my inattention!

Albert FR

@Martin+Konecny:

for information, on the latest snapshot, crossfade not working between the songs, blocks, playlists, webstream

Howdy, Stranger!
