splitmuxsink not working with opusenc

[Abu Abdullah]

Hi,

the following pipeline is not working:
$ gst-launch-1.0 alsasrc ! audio/x-raw,channels=1 ! opusenc ! oggmux !
splitmuxsink location=%03d.ogg
WARNING: erroneous pipeline: could not link oggmux0 to splitmuxsink0

using normal filesink is working fine:
$ gst-launch-1.0 alsasrc ! audio/x-raw,channels=1 ! opusenc ! oggmux !
filesink location=dd.ogg


platform is Raspberry pi with gst 1.16.2

any help is appreciated
