Re: [Banshee-List] passing options to gstreamer

[Benj FitzPatrick <benjfitz yahoo com>]

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 using 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:

 ~/.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
pipeline...
