ffplay/ffmpeg on RTMP with H264-encoding

I'm trying to play an RTMP encoded with h264 using the Flash Player 11 h264 encoder - with ffplay.

It works. But only if the stream is set with a bitrate of 64KB and the keyframe interval is 4.
Otherwise it cant find any frames.

Any ideas why?

Yay, it's finally working!

you need to set some options in the application.xml for the app that streams the video in the FMS,
basically cancel-out things related to buffering:

[under StreamManager/Live:]

<AccumulatedIFrames>
   <MaxTime>0</MaxTime>
   <MaxSize>0</MaxSize>
</AccumulatedIFrames>
<Queue enabled="false">
   <stuff that doesn't matter when you set enabled above to 'false' />
</Queue>

Also, I think this helps too:

<Client>
   <MsgQueue>
      <Live>
         <MinBufferTime>0</MinBufferTime>
      </Live>
      <Server>
         <BufferRatio>0</BufferRatio>
      </Server>
    </MsgQueue> 
</Client>

Also, set bufferTime to 0 in the netstream object of the client that broadcasts the stream.
