[gst-devel] Setting volume for playbin

[Danilo Freire]

thats weird,

The runtime error is because G_Obejct just check the property set when it is
set.

but the problem with the volume change, I have no glue. try to run using:

gst_launch -v playbin uri=file:///somewhere volume=10.0

and look for some problem in the verbose messages. If necessary use:

GST_DEBUG=3 gst_launch playbin uri=file:///somewhere volume=10.0
