<div dir="ltr"><div>I have the following pipeline: giosrc location=my_remote_location ! wavparse ! adpcmdec ! audioconvert ! audioresample ! audio/x-raw,rate=8000,channels=1,format=S16LE ! wavenc ! fdsink </div>I use the stdout of the process that runs this pipeline to stream the PCM audio to the client. But on the end of the streaming i always get the error: <div> <div> ERROR: element fdsink0: detail: Could not perform seek on resource.
