Developing a streaming camera phone application

Question

hi all,

i'm thinking about developing an application which would allow one to use the LUMIA 1200 as a live webcam feed. Thus, the idea is basically to use USB or home network to stream the feed to a windows app.

I've been reading thru some articles. Basically I was wondering it it would be possible to use the playto API to stream live content from the camera phone. And if so, wondering if anyone did it before. I can not find any app clearly pointing this out, nore documentation about playto API.

Thank you,

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.

Hello,

At this time we don't support PlayTo natively on Windows Phone 8. This feature is only available on Windows 8.x. Unfortunately there is no easy way to work with raw video data and codecs on Windows Phone 8. It is possible to get the raw video stream by using the VideoSink and then overriding the OnSample method. This will give you uncompressed frames in a format such as YUV. You should never request ARGB or RGB frames due to performance problems. Working with compressed formats such as mp4 can be complex and at this time it doesn't appear that we support the real time MP4 codecs on the phone.
