How do I stream data into deepstream-app via rstp?

I am using ffserver with the following config to push video file into stream:

Port 8090 
# bind to all IPs aliased or not 
BindAddress 0.0.0.0 
# max number of simultaneous clients 
MaxClients 1000 
# max bandwidth per-client (kb/s) 
MaxBandwidth 10000 
# Suppress that if you want to launch ffserver as a daemon. 
NoDaemon 

<Feed feed1.ffm> 
File /tmp/feed1.ffm 
FileMaxSize 5M 
</Feed> 

<Stream test.swf>
Feed feed1.ffm
Format swf
VideoCodec flv
VideoFrameRate 15
VideoBufferSize 80000
VideoBitRate 100
VideoQMin 1
VideoQMax 5
VideoSize 352x288
PreRoll 0
Noaudio

I can watch it with ffmpeg like this:

ffplay http://SERVERIP:8090/test.swf

If I replace uri in working deepstream config:

...
[source0]
...
uri=http://SERVERIP:8090/test.swf
...

then I get this error:

how can I fix it?

could you refer this
https://docs.nvidia.com/metropolis/deepstream/4.0/dev-guide/index.html#page/DeepStream_Development_Guide%2Fdeepstream_app_config.3.2.html%23wwpID0E0QB0HA

I don’t see solution for the error there.

Not sure if you can try RTSP

Try to use flvdemux
