Whats described there within section "zoom" is what we are actual doing. I took some screen shots of a broadcast which is 4:3 aspect with encoded black bars (letterboxed video). It is displayed via xv-out in a 1024x576 window. http://lucke.in-berlin.de/aspect-crop/DSC00082.JPG The initial crop mode is none, so I get black borders on all 4 sides. http://lucke.in-berlin.de/aspect-crop/DSC00083.JPG Now when I select cropmode 16:9, the corresponding 16:9 part of that video is taken and displayed in the whole area of the window. http://lucke.in-berlin.de/aspect-crop/DSC00084.JPG So I've a small problem in understanding what might be wrong in our zoom/crop-modes. -- Stefan Lucke _______________________________________________ Softdevice-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/softdevice-devel
