Sony Network camera H264

Wowza Streaming Engine
1

Hey :slight_smile:

Just bought a Sony SNCDF50N With H264 support and RTP Protocol support.

But there is no RTSP support.

Is it possible to use this Camera with the Wowza Pro Server ?

Do I need an Encoder in the middle ?

I seems that it did. I didn’t dig into any deeper but I think the document goes on to define the format of the packets. I am pretty sure it is not using any of the standard packetization formats. See if you can get VLC to play the stream. I can’t remember if I tried this or not.

I can set the RTP Video and RTP Audio ports in the Admin.

Its standard 50000 and 50001.

Any clues anyone ?

I can set up a Sony camera in my DMZ zone to test Charlie.

But have to wait until tomorrow :slight_smile:

You need the SDP data to play the stream. See if you can find a way to export the SDP data or get the SDP data from the Sony web site.

Try using this as the content of the SDP file:

v=0
o=- 2580329803 1 IN IP4 127.0.0.1
s=WowzaPro
i=WowzaPro
b=AS:1048
t=0 0
m=video [port] RTP/AVP 96
b=AS:1000
a=control:trackID=111
a=rtpmap:96 H264/90000
a=fmtp:96 packetization-mode=1

Where [port] is the port number that the video is being stream to. Follow these basic instructions to stream:

Does your Sony webcam support native RTP streaming of H.264? What is the model number. If you have host the camera on the internet for me to take a look at let me know directly by email (charlie@wowza.com). I will see what I can do.

The RTP packets do not use a standard format. So they will not work with Wowza Pro.

I will consider it. I can’t promise when I will have time to do this work. It is a non-trivial task.

We have not added support for this cameras RTP packet format.

We still have not added support. Double check with Sony. I talked to them and they claimed that there were very few models that used the strange format. Do be sure to get the latest firmware from Sony.

Try following this guide:

And use the rtsp url Sony TechSupport describes in the previous post in this thread.

Sander,

There are some suggestions in this thread that might help you.

You might be sending mpeg4 part 2 with that setting, not h.264 (mpeg4 part 10).

I have the same problem with my Sony webcam as well. Wowza does seem to receive the video stream, but I get a constant stream of unrecognised frame errors in the console. Charie, do you offer consultancy on this problem? I’m willing to pay $$$ to get this problem resolved.

Let’s hope this will work…

16

The manual clearly states that “the camera will send the MPEG4 or H.264 raw data as its response”. This data is transported using RTP. Which is a protocol. I can hardly imagine Sony would invent its own protocol…

This might help:

I still hope it’s just a matter of skipping the Sony specific frames (their so called “user-data”) and accepting the “standard” ones.

18

Yep, I just read through the entire document, this indeed describes the protocol Sony used. Give us a chance, pleeeeeease!

19

Any news on this?

Can this be used ?

Acquisition of RTP(Unicast) bit stream

(H.264 mode)

I found this document on their website http://ws.sel.sony.com/PIPWebServices/RetrievePublicAsset/StepID/SEL-asset-42545/original/mpeg4_h264_jpeg_user_data_doc_1.0en.pdf

Not much about SDP data.
