- We're using the IndigoVideo board, and we're simulating some hardware
- that has a 3:1 aspect ratio. We would like to save to disk and later
- display some video with a 3:1 aspect ratio (320 wide, 107 high).
-
- We could capture at 320x240 and just overlay a border to get 3:1, but
- we were hoping that, since we only need 320x107, if we captured at that
- size we could reduce disk space needs, and if we displayed at that size
- we could update faster.
-
- For capture, we're started with the "svtomovie.c" example code. Using
- 320x107 and calling "svOpenVideo()", "svSetSize()", "svBindGLWindow()",
- we get a 320x107 window. Then upon calling
- "svQueryCaptureBufferSize()", with svCaptureInfo set for a 320x107
- window, it returns svCaptureInfo reset for a 320x240 window.
-
- So, questions:
- 1) {can | how do} we capture at aspect ratios beside 3:2?
- 2) {can | how do} we display at a different aspect ratio?
-
- Thanks for any help.
