General discussion

I have moc 2.5.0_alpha4 compiled on gentoo with gcc 4.6.2, glibc is 2.13-r4. Sometimes it crashes with ** glibc detected *** mocp: free(): invalid next size (normal): 0x082b1c70 *** or similar error. I can't exactly catch the moment when it crashes. After showing this error and freezing interface moc continues to play. If I kill the interface and then start it, it freezes on getting playlist. The same problem was with previuos versions of moc and glibc.

Hello.

I've build some moc RPMs 32/64 bit for Fedora (14/15/16).
They are stored here: http://sagitter.fedorapeople.org/moc/

Now i'm trying to build the development version in wait of Fedora 17, however the dash ('-') of package name prevents me to use "rpmbuild" tool.
Can i do something to get over this problem ?

Regards.

How do I solve this error?

I have MOC working before but it will not work now. It is giving me so many errors and this is the latest one.

I have all the files listed here:

http://packages.ubuntu.com/natty/amd64/moc/filelist

including ~/home/***/.moc/config

and all the dependencies listed here:

http://packages.ubuntu.com/natty/moc

but I get this:

$ mocp
Plugin uses different API version
Plugin uses different API version
Plugin uses different API version

FATAL_ERROR: Tried to get wrong option 'ModPlug_Oversampling'!

Hello !

With my Fedora 16 64bit the moc-2.5.0alpha4 compilation stops with some errors.

Please, can someone explain me how to resolve this problem ?

I am running Debian Unstable with OSS and cannot figure out how to get moc to use the mixer.

In moc I receive the error: (46766!) Can't read from mixer.

Also, I left moc running without a song playing and came back to find all my ram exausted and page file maxed out by the mocp process.

I have tried the following mixers against OSSMixerDevice in ~/.moc/config which I found.

/dev/mixer
/dev/mixer0 (/dev/mixer0 -> /dev/oss/oss_hdaudio0/mix0)

Currently the config is:

> grep OSS ~/.moc/config
# Sound driver - OSS, ALSA, JACK, SNDIO (on OpenBSD) or null (only for
SoundDriver = OSS:ALSA:JACK
# OSS output device.
OSSDevice = /dev/dsp
# OSS Mixer device.
OSSMixerDevice = /dev/oss/oss_hdaudio0/mix0
# OSS Mixer channel: pcm or master.
OSSMixerChannel = pcm
# Second OSS Mixer channel: pcm or master.
OSSMixerChannel2 = master

Hi there,

Some months ago i've written a little plugin for MOC player in order to properly scrobble my library to my LastFm account.

I think it will be usefull for some guys.

Simply follow few steps described here:

enjoy!

Hi, I'm trying to use MOC as a sample browser, unfortunately very short WAV files, like percussion hits, just create a kind of dull click sound - longer samples seem to work fine. I'm running Arch and installed MOC via pacman and copied the example config specifying ALSA as the only driver. I know ALSA is working correctly, using "aplay sample.wav" plays the WAV correctly.

Any ideas would be greatly appreciated.

Thanks, Paul
