Setting volume for playbin

Hi,

Is it possible to set the volume for Playbin element?

When I try to set the volume , says GstPlayBin has no property named.

Regards,

Akbar

Re: Setting volume for playbin

I used the below code to set the volume.

        play = gst_element_factory_make ( "playbin", "play" );
        g_object_set ( G_OBJECT(play), "uri", argv[1], NULL );
        g_object_set ( G_OBJECT(play), "volume", 10.0, NULL );

I muted the volume by using the volume control and played the audio file with volume range 1.0 and 10.0. I'm able to hear the sound but couldnt
make out the difference between the range 1.0 and 10.0 as the sound emitted for the range 1.0 and 10.0 seems to be same.

I raised the volume to the full by using volume control, i got the same behavior as above. It seems for the volume range 1.0 and 10.0, sound
is same. I could make a slight difference for the range 0.1/0.2.

Moreover if i give the volume as int/unsigned int rather than double as g_object_set ( G_OBJECT(play), "volume", 3, NULL ); it throws a runtime error
(a.out:13506): GLib-GObject-WARNING **: IA__g_object_set_valist: object class `GstPlayBin' has no property named `\x81\xc3\xdb\xc4\u0003'.

Is there any way to get/set the balance level?

Re: Setting volume for playbin

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

Re: Setting volume for playbin

Sorry for the late reply as I was on vacation.

When i execute the following the code with volume as integer values gives the warning message without the sound. When the volume is either floating point or casting to double it plays perfectly.

g_object_set ( G_OBJECT(play), "volume", 10.0, NULL );

It gives runtime error when the volume type is unsigned int . Like the following code

unsigned int val = 8;
g_object_set ( G_OBJECT(play), "volume", val, NULL );

Where as in command line it works without any of the above hassles.,

Thanks,

Akbar

What is the problem here. This is to be expected. If you run "gst-inpect
playbin" and look for volume - it's double. g_object_set() is a varargs
function and parameters have to be in the right format (and terminated
with NULL). gst-launch is an entirely different thing. its a tool and it
tries to be helpful.

Re: Setting volume for playbin

In reply to this post by Ganesh Kundapur

You must pus the object set in while(1) loop
