For reference, here is one relevant part:

<Stream test.mp4>              # Output stream URL definition
   Feed feed1.ffm              # Feed from which to receive video
   Format mp4

   # Audio settings
   NoAudio          
 
   VideoCodec libx264
   VideoSize 1280x720           
   VideoFrameRate 25          
   AVOptionVideo flags +global_header  
   AVOptionVideo cpu-used 0
   AVOptionVideo qmin 10
   AVOptionVideo qmax 42
   AVOptionVideo quality good
   AVOptionVideo me_range 16
   AVOptionVideo qdiff 4
   AVOptionAudio flags +global_header
   PreRoll 15
   StartSendOnKey
   VideoBitRate 1M
</Stream>

It seems this is an FAQ. Most answers hint that mp4 is not a suitable
format, despite "flags +global_header".

If you replace the above config with flv:
<Stream test.flv>
   Feed feed1.ffm
   Format flv
[...]

and access the appropriate URL with ffplay
(http://localhost:8090/test.flv), it works fine (for me).
