how to tune amarok/xine streams

Fri Oct 01, 2010 10:52 pm
<Amarok newbie warning>
OK - I've pretty much exhausted everywhere I think I know to look for this:

The system:
openSUSE 11.3 - fully updated

Using Amarok Version 2.3.0

With a stream from: http://66.162.107.142/cpr1_K128OV.ogg

(or anywhere else)

I get 1-2 second "skips" most every 16-19 seconds. My presumption is that I need a larger buffer (windows and Mac iTunes on this same connection work fine)

I can't find where xine finds/sets buffer size (e.g. the name and syntax of the configuration file to use).

Or, are there other problems/solutions?

Please help.

Thanx,
Lew

1st upgrade Amarok to 2.3.2 http://software.opensuse.org/search?q=a ... debug=true

The stream plays fine for me (note: I am running Amarok git)

did you try adjusting ~/.xine/config, not sure if it's for the gui and/or the backend:
# number of audio buffers
# numeric, default: 230
#engine.buffers.audio_num_buffers:230

Also you could try the phonon-backend-vlc http://software.opensuse.org/search?q=p ... USE%3A11.3, there's also a gstreamer one

Did upgrades as suggested above:
  1. Xine - behaves as before.
    • Created a ~/.xine/config file and tried a few buffer settings
    • None of the buffer settings seem to affect the problem
    • Is there a way to get the xine back end to tell me what it's using for buffers? I'm still not sure the syntax I'm using or the file I have has any effect
    • It might be something other than a buffer problem - seems to not always happen at the same point in the block which makes me think there might be some sort of reassembly problem? thoughts?
  2. I tried VLC and couldn't get anything to play (either test sounds or streams)
    • Any thoughts about what might be missing?
  3. I tried Gstreamer and it's been playing fine for 15 minutes
    • I see that Gstreamer is strongly discouraged in these forums
    • Any thoughts about ether VLC or xine solutions would be appreciated

Many thanx,
Lew

Phonon uses it's own seperated xine configuration file. It is located inside ~/.config/ ( kde.org/phonon-xine.conf from memory ) and is the same format as the usual xine configuration file.

In openSuse there's 3 repos with VLC (Packman, Playground and VLC's own)
- Playground only plays free codecs (flac and ogg) for legal reasons
- VLC's tends to be discouraged because it can conflict with other repo's iirc
- Packman doesn't provide a phonon-backend rpm but plays all codecs

The rpm's I pointed to (and which you installed) might not work with what you have installed?

PS I emailed the Packman VLC maintainer requesting they provide one.
