Convert RTSP feed from BCD536HP with FFMPEG

[va2yml]

Is anyone been able to convert an RTSP feed from a BCD536HP to a UDP feed using FFMPEG?

I've tried to listen to the feed with FFPLAY with no succes. I alway end up with a "server bad request - error 400".

The feed is playable fine in VLC.

Here is a screenshot of the VLC RTSP connection sequence.


And the catpure of the same connection using FFPLAY (FFMPEG)



As you can see, I'm forcing a TCP connection (FFPLAY use RTSP over UDP by default).
I have developped the content of the SETUP packet because the bad request status come right after this command.

I'va tried lot of flags / parameter with ffplay... always the same result.

Anyone has a magioc formula to listen to this feed?

I think it's the Transport line. Should be like the VLC example which is:
Transport: RTP/AVP;unicast;client_port=38032-38033\r\n
