Get live stream image every frame on Wowza server

Wowza Developer Dojo

Hello everybody,

I am a new member. I would like to use Wowza for my live stream server. Our target is IoT product. Every robot will live stream to the server.

On our server, we implement many computer vision function. So, now we want to get image at every frame for call computer vision function.

I would like to ask you there, if that is possible to do that?

I don’t know if we can use this solution: https://www.wowza.com/docs/how-to-get-thumbnail-images-from-wowza-transcoder-with-an-http-provider

I confused because we need to get image every frame. So we need a great solution.

Thank you in advance!

Hi,

The example there is for generating a thumbnail each time the provider is called. It’s not intended to be called every frame - that would incur a very large overhead, potentially 30 or more times per second depending on your frame rate. It also requires the use of the Transcoder. There is also a newer option for this that doesn’t require the Transcoder, and we have some detail on how that can be used in this article. I would only advise that you test it yourself, but as said it may not be the most efficient way to do this.

Regards,

Paul
