Quasi hardware decoding through XvMC (/*XV*ideo *M*otion > *C*ompensation/) with low CPU load vidix is not XvMC. vidix is a library for direct access to the graphics hardware's overlay buffer. It allows writing pixelvalues directly, avoiding any X server or console fb api interaction. The graphics hardware will do scaling and colour space conversion. XvMC is an X11 extension, so requires an X server. I think there are libraries to do this without an X server when using epia hardware, but I am not familiar with it. > Or this?: > > * Software decoding.

This is because vidix itself doesn't know how to set up refresh rates and other parameters to get the graphics card running. It only knows how and where to push pixels. And it has nothing to do with v4l or XVideo. -- Torgeir Veimo <torgeir@xxxxxxxxx>
