MV Network Renderer and MV Network Source

[duncanh]

Hi,

I am new to imaging and the montivision products, have downloaded the demo product and have a question.

I would like to know if there is an example demonstrating both/either :

MV Network Renderer and MV Network Source

I understand that I could use this to stream video over tcp/ip, perhaps from a local PC to another remote ip address?

Thanks for any help.

Cheers,

Duncan.

Hi Duncan,

On PC One in the network setup the following simple configuration in the Workbench for a first test:

Video Capture Source -> MV Network Renderer

Select the desired port and destination computer on the property page.

On another PC open MV Network Source in the workbench, choose port and sender computer on the property page and check if the partner is available. If so, right click on the output pin of the Network Source and choose "render".

Start both configurations in order to see the video sent by PC One on PC two. To limit the amount of data, add a video compressor to the sender:

Video Capture Source -> Compressor -> MV Network Renderer

I hope this helps!

Hi Marc,

Thanks for the reply. I am still not sure however on one or two points.

When I add the "MV Network Source" and then right click I get "BDA Slip De-Framer" added. I don't seem to be able to attach any sort of video output to the pin.

How do I know what can connect to what?

Any advise is appreciated.

I have looked through the help files, but have not had much success!

Cheers,

Duncan.

Hi Duncan,

Is it possible for you to send the sender MVP file to support@montivision.com?

Hi Duncan,

Thanks for the files, we already know the issue. If you connect a camera directly to the network renderer, the renderer will accept any media type. If the camera (as we think yours does) offers compressed output media, then it installs a decompressor filter for this media types. On your client machine you do not have this decompressor and you can't render the stream.

To make it easiert to handle this, we developed a media tpye selector filter which is inserted between the camera and the renderer. It will ask you to accept or decline the offered media types. You should accept only commonly used formats as RGB.

This new filter will be part of Version 2.2 which will be released on friday.

Another solution for now is to insert the capture filter and renderer it to a video renderer. Then deconnect the video renderer and connect the network renderer.

I hope this helps!

Hi Marc,

Does this affect the BroadcastClient.mvp file I sent?

It is in this file that I cannot get a video output connected, and am having problems. The BroadcastServer.mvp seems fine to me.

I have MV Network Source -> BDA Slip De-Framer -> BDA IP Sink in BroadcastClient.mvp

Cheers,

Duncan.

Hi Duncan,

You have to change the Broadcast_Server.mvp as it sends wrong media types. Try the following on the server:

Camera -> MV MJPEG Compressor -> Net Renderer

and in Client MVP file:

Net Source -> MV MJPEG Decompressor -> Video Renderer

The problem with your MVP files is that the server sends media samples that can't be decoded by the client as the decompressor is not installed on that machine. The decompressor is installed with the camera.

Thanks for the help, it seems to be working now!
