Thanks for reply! If the end goal is to process video and pass frames to module to do further processing (like barcodes), then unfortunately the mobile ACS Calling UI SDKs do not support this functionality at the moment.
The mobile ACS Calling UI SDK only supports setting up audio/video calling experience and we have sample for both Xamarin and MAUI depending on what you are looking for.
Also you may want to know that Microsoft is pushing folks towards MAUI rather than Xamarin since MAUI is actively being worked on and will have more support compared to Xamarin going forward.
Xamarin Sample: https://github.com/Azure-Samples/communication-services-ui-library-xamarin
MAUI Sample: https://github.com/Azure-Samples/communication-services-ui-library-maui
Please note that we are not officially supporting Nuget packages for these bindings at the moment. You need to go through the sample and create the binding themselves in their own code repository by following the Samples above.
Having said if you have any feedback related to product please share here: https://feedback.azure.com/d365community/search/?q=Azure+Communication+services
The product team is actively looking into this and provide response accordingly.
Hope this helps.
