Hi,
I have been looking for a way to tune the contrast of the overlay plane (for video playback) on OMAP3530. I have been asking questions on the rowboat google group (http://groups.google.com/group/rowboat/browse_thread/thread/904e68c3ead18854?hl=en, also shows the original problem I am trying to address) and on the #rowboat IRC channel to eventually arrive here...
The "Linux PSP user guide" references to the use of V4L2_CID_CONTRAST ioctl to be able to control the contrast of the display. But the code I am using (rowboat / froyo / 2.6.32) does not seem to support that, it only supports V4L2_CID_ROTATE/ V4L2_CID_BG_COLOR/ V4L2_CID_VFLIP...
And I don't find any way in the OMAP3530 TRM to be able to control that (the closest I have found is gamma correction and color map...).
Any idea on how I can control that ? (or solve the original problem, see in the google group post).
Thank you,
Matthieu
