RTSP to Live Hardware Encoder

Hi All,

I’m trying to connect Wowza to hardware encoders from ACTI and BOSCH by RTSP + RTP.

After some trial, I’ve been able to get the SDP informations, but, when I run the rtplive client application, Wowza don’t ever try to connect to the devices (I’m monitoring connection with Ethereal).

Here are the SDP, anyone can help me?

Some other notes:

These devices don’t provide a way to get the SDP file, I’ve been able to capture the SDP infos by spoofing packets of data with ethereal, and compile them in a textual file. I used VLC, which is able to display the video streams, to analyze the sessions.

Here are the RTSP capture conversation:

It would be nice to have a feature on Wowza for opening these streams by giving these “rtsp://” urls instead of a SDP file…

You don’t have the port numbers in the SDP data.

v=0
o=- 0 0 IN IP4 192.168.2.205
s=LIVE VIEW
t=0 0
m=video [port] RTP/AVP 36
c=IN IP4 0.0.0.0
a=rtpmap:36 H263-1998/90000
a=control:rtsp://192.168.2.205

Replace the [port] part in the above SDP data with the destination port of the stream.

It looks like these encoders do not support H.264/AAC-HE. Ceratainly the ACT one does not. The MP4V-ES is not supported by the Flash player. Only MP4-AVC is supported.

The other encoder is sending H263-1998 which we do not support. There is a chance we can get this to work but we currently do not have a depacketizer for H.263. Only for H.264.

So as of right now Wowza Pro/Flash will not work with these encoders.

Charlie

It is helpful. I do want to play with this more to see if there is a simple way to make this work. I will post back if there are any developments. Too bad this didn’t just work. I appreciate your patience and the good information.

Charlie

We added this feature to Wowza Pro. Install patch10 from here:

https://www.wowza.com/devbuild.html

As long as the server supports RTSP DESCRIBE then it should work. Also, take a look at the new documentation that is included with the patch. Search for the following settings. It describes how to setup the stream so it restarts the the stream when the SDP data changes:

<MediaCaster>
	<Properties>
		<Property>
			<Name>streamTimeout</Name>
			<Value>2000</Value>
			<Type>Integer</Type>
		</Property>
		<Property>
			<Name>sdpFileCheckFreqency</Name>
			<Value>2000</Value>
			<Type>Integer</Type>
		</Property>
		<Property>
			<Name>sdpHTTPCheckFreqency</Name>
			<Value>2000</Value>
			<Type>Integer</Type>
		</Property>
	</Properties>
</MediaCaster>

Here are the DEBUG infos when trying to connect to Wowza and opening the stream related to the SDP file of the ACTI:

It would be nice to have a feature on Wowza for opening these streams by giving these “rtsp://” urls instead of a SDP file…

I’ll second that … the SDP stuff is complete voodoo.

Sorry, I did not fully understand your first post. Now I do. Take a look at the instructions for the Haivision Oscar:

https://www.wowza.com/forums/showthread.php?t=1354

In Wowza Pro 1.5.2 we added the ability to connect to an rtsp source. I have not tested anything beyond the Haivison Oscar but I did try and implement it in a generic way. See if this setup works with your encoders.

Charlie

Ok, I try and let you know in ten minutes…

It seems that it negotiate which port to use using RTSP:

Look at this RTSP Setup Request (using VLC):

SETUP rtsp://192.168.2.205 RTSP/1.0
CSeq: 3
Transport: RTP/AVP;unicast;client_port=2112-2113
User-Agent: VLC media player (LIVE555 Streaming Media v2008.05.12)

and the relative response of the encoder:

RTSP/1.0 200 OK
Transport: RTP/AVP/UDP;unicast;server_port=4708-4709;client_port=2112;ssrc=4294967295;mode=PLAY
Cseq: 3
Session: 87

Which port is to be used on the SDP m= ??

I’m going to spent another hour on it, if I find somthing interesting I will post it, else, I hope these info could help on improving Wowza features.

It is not still working, but the overal situation it is better, maybe I’m near the solution:

here the RTSP negotiation by Wowza (Bosch encoder, later I’ll try the Acti one)
