I am writing some video files under Windows from a camera. I need the data unaltered - not MP4's 'uncompressed' ie. no YUV, no color interpolation - just the raw camera sensor bytestream. At the moment I am writing this direct to disk and re-reading it later to recode into a usable video. But with no header I have to keep track of image...
I need to capture the content that (Win7) Mediacenter is displaying. My first approach was to use the Win7 Live Thumbnail Preview for this, but this only works as long as Mediacenter is not fullscreen. As soon as I switch to fullscreen mode, the thumbnail become black. This seems logical, because MC switches to a DirectX mode (for GPU ha...

Hello, In a nutshell, I need a way to stream (or otherwise play) a movie along with 3 to 4 other 'show angles', with the user being able to change the stream they're viewing. End result should be a video player with links/buttons for the other angles, allowing the user to switch camera streams (angles) as they wish. Here's an example: ...
Hey folks. Trying to get started with iPhone video capture stuff, and having a terrible time getting it going. At the moment, working with an exact copy of the sample code from this Apple Developer Q&A: qa1702; not going to re-paste it here, since it's a relatively big blob of code. In any case, I copied and pasted that code into an o...
Hello, when I perform a cvQueryFrame on Windows, the API blocks until an image is delivered. On Mac OS X, I am at 100% CPU utilization, while only querying for an image and displaying it in a window.
