I am trying to access the video output from a Bluefish Neutron card and display it in an AIR desktop app.

I have plenty of experience loading and displaying both local and streaming video but none at all about how to access a video card.

Can anyone give me any pointers on how to start with such a task?

Many thanks.

You would need to use something like FFmpeg to capture the video, convert into flv w/H.264 and pipe out as a byte array stream which you can play as a live feed using NetStream.

Luckily there already exists an ANE that wraps FFmpeg and that will allow you to do this.

Using a combination of these 2 examples

1. Capture as DirectShow input

AVANE/DesktopCapture.as at master · tuarua/AVANE · GitHub

2. Stream encoded data into a NetStream

AVANE/UniversalPlayer.as at master · tuarua/AVANE · GitHub

Hi el111,

Many thanks for your reply.

However, I'm a little stuck on how to use your reply - am I supposed to use the ANE or the two class files you referenced and is there any examples of how to use these files/ANE?

Any example would be very much appreciated.

Thank you.
