Simulcast support? Relaying from rtmp source?

[mpisat]

Hi,

I'm able to pull rtmp after so many attempts (gstreamer is difficult)

./gstreamer-publisher --token $LIVEKIT_PUBLISH_TOKEN
--
rtmpsrc location="rtmp://someserver/live/streamname" do-timestamp=true !
queue max-size-time=2000000000 leaky=upstream !
flvdemux name=demux
demux.video ! queue max-size-buffers=4096 leaky=upstream !
decodebin ! videoconvert !
x264enc tune=zerolatency key-int-max=60 bitrate=2000 name=vout
demux.audio ! queue max-size-buffers=4096 leaky=upstream !
decodebin ! audioconvert ! audioresample !
opusenc bitrate=64000 name=aout

I was wondering if we can do simulcast either by pulling 3 resolutions from the other rtmp source (stream_1080p, stream_720p, stream_360p etc) or by transcoding with gstreamer?

Do you have plans to improve this tool? It can help integrating other sources into gstreamer.
