Re: [Banshee-List] passing options to gstreamer

[Benj FitzPatrick <benjfitz yahoo com>]

Sorry for replying to my own mail, but I thought I should send an update.  Gstreamer from the command line still sounds choppy but banshee sounds great! :)  In the end that's all that matters to me, thanks so much for everybody's help.

Ok, just for the record here are the two different ways I have tried invoking gstreamer from the command line:

gst-launch-0.8 playbin uri="file:///absolute/uri/to/file.mp3"

gst-launch-0.8 filesrc location=/home/benjfitz/temp/test.mp3 ! mad ! alsasink

I setup my custom sink (thanks Ed), now how do I access it using gst-launch?  I tried custom, Custom, default, and Default, but none of them worked (this was with the second invocation).  With the first one it still sounded choppy as if it were still u sing alsasink without the options.  Sorry if these are all very n00b questions, but google isn't turning up much and neither is the gstreamer documentation I can find.  If it is covered some where please let me know where so I can RTFM. :)

I also tried adding the dmix option from the command line, but I get the following error:
--------------------------------------------------------------------------
benjfitz be njfitz ~/.gstreamer-0.8 $ gst-launch-0.8 filesrc location=/home/benjfitz/temp/test.mp3 ! mad ! alsasink device=dmix period-size=1024 buffer-size=4096

Just glancing through the document you linked me, it seems you should be
setting "device=dmix" on the alsasink element in your custom audio sink
