Re: Problem with NDISRC, WHIPSINK, and audio

Hi,

What is the idea behind fixing the sink pad number i.e., sink_0 to video
and sink_1 to audio ? The pads would be linked dynamically anyway.

Can you try the below modified pipeline. I have also added a queue in audio
branch after demux.

*gst-launch-1.0 ndisrc ndi-name="NDIPE8 (SIGGEN)" !  ndisrcdemux name=demux
demux.video ! queue ! videoconvert ! x264enc !
video/x-h264,format=byte-stream,profile=baseline ! rtph264pay !
'application/x-rtp,media=video,encoding-name=H264,payload=97,clock-rate=90000'
!  whip. demux.audio ! queue ! audioconvert ! opusenc ! rtpopuspay !
'application/x-rtp,media=audio,encoding-name=OPUS,payload=96,clock-rate=48000,encoding-params=(string)2'
 !  whipsink name=whip   auth-token="…redacted….."
 whip-endpoint="https://director.millicast.com/api/whip/myStreamName
<https://director.millicast.com/api/whip/myStreamName>”*
