No sound coming from scheduler - Airtime Support Discussions on Sourcefabric Forum

Aramil

Hi, I have been running Campcaster without any problems for about a month now.Yesterday I scheduled some playlists, the first one started playing but at some point it stopped.Since then nothing comes out of the scheduler.

Any ideas?

Douglas Arellanes

Hi Aramil,

This is usually caused by a file which in some way gave the scheduler problems - perhaps it was in a format it does not understand such as Apple's AAC?

If you are in testing mode, please try to restart your computer and start Campcaster from the terminal. If you have the time and ability to test it, please try to replay that playlist and also to examine the files in it. At least then it will provide you with more information about what went wrong.

Also, I'm assuming there were no other programs accessing the scheduler's sound card, right?

Hope this helps,

douglas

Hi and sorry for the late answer.What seems to be the problem is that for no particular reason scheduler crashes whith playlist that we 've been using about a month now (with no problems at all).

This is the output of the scheduler when I start it from SSH :

I can't figure out what's going on..All files are mp3 and as I said everything run normal for many days now...

Douglas Arellanes

This is a strange problem indeed. I'm trying to narrow the problem down - is it a bad playlist (or items inside the playlist) or is it another problem inside the scheduler? If you're able to narrow the problem down to a certain playlist, we can start to look at what is in the playlist that is making it crash.

One other question: Does the playlist in question have offset values (i.e. start the file at :12 seconds from the beginning and end at :24 from the end?)

Aramil

ΟΚ, i tested many playlists, it seems that there is only one causing this problem.Although all files are mp3.I'll try deleting and re-inserting the songs ( i use simlinks to import to campcaster so maybe that's what causing the problem).

By the way, no offset values are used.

P.S I plan to migrate campcaster to another computer because this one is making my life very difficult (1.5Ghz Celeron,384 RAM).Is there a secure way to make a complete backup of the music library and playlists?

Douglas Arellanes

Hi Aramil,

I'm glad to hear that you've narrowed down the problem with the playlist.

There is a very easy to use tool for making backups of your storage items - you can back everything up (which will make a very big file and probably take a long time), or you can back up using search criteria.

This is in Campcaster Studio -> Options -> Backup. It's also described in the manual here:

http://en.flossmanuals.net/Campcaster/OptionsPalette

Hope this helps!

Thanks a lot for the information.I have now completed the backup and I' m trying to install the Development Environment on the new PC.Unfortunately during the setup I get these errors

Suggestions?

Aramil

HI everyone!

After a long summer I still can't find a solution for this!Can anyone give me some guidance please? Very Happy

Daniel James

Hi Aramil,

> After a long summer I still can't find a solution for this!Can anyone
> give me some guidance please?

Using the development version for a production system is not
recommended. Please try the .deb package installation on an Ubuntu
Karmic machine, as shown here:

http://en.flossmanuals.net/Campcaster/InstallSynaptic

If the problem with the rogue playlist persists after installation of
the .deb package version, please make a backup of that specific playlist
and post it online, so that the developers can download it and try to
reproduce the bug.

Cheers!

Daniel

The rogue playlist problem is solved, the problem with the installation on the new system persists (i pasted the error log on a previous post).

Unfortunately we are using lucid and as far as I know there are no deb packages yet...

Daniel James

Hi Aramil,

> Unfortunately we are using lucid and as far as I know there are no deb

Packages have been made, but changes in Ubuntu between Karmic and Lucid
have broken functionality in the current release of Campcaster.

Therefore if you want to use Campcaster now, you are better off
downgrading your Ubuntu installation to Karmic, which is still a
Canonical supported release until April 2011.

Cheers!

Daniel

Howdy, Stranger!
