using mulaw decoder

[Vinod Nanjaiah]

Hi,

I am trying to playback a mulaw audio file using the following pipeline construct:

 

gst-launch-0.10 filesrc location=$1 ! mulawdec ! osssink

 

But, I am getting this error:

 

ERROR default mulaw-decode.c:199:gst_mulawdec_chain:<mulawdec0> no format negotiated

 

Is there any other element that I need to include in the pipeline?

I tried using audioconvert (after mulawdec), but got the same error.

 

what could be the problem?

BTW, I am trying this on Da-vinci platform.

 

Best Regards,

Vinod Pura

Maybe adding capsfilter after filesrc would work (or typefind)
