Unfortunately there's no easy way to fix this, other than using a real operating system (one that treats open files as sockets). I suspect that - if you want to stick with Windows - you will need to write your own "FramedSource" subclass to encapsulate your video capture device, and use that instead of "ByteStreamFileSource".</div><br><br><div apple-content-edited="true">
