I try to output video on a CVBS display (from iMX53 with linux-2.6-imx-rel_imx_2.6.35_11.09.01 kernel from Freescale).
The display accepts PAL video format, so I use this kernel command line arguments :
video=mxcdi1fb:TV-PAL tve ldb=off
Thus my /dev/fb0 is displayed on the screen... but not entirely !
The image is cropped by about 30 pixels (left and right) and 15 pixels (top & bottom) [This is a rough estimation]
With an old TV, the image is cropped almost the same (but not exactly) and not cropped top and bottom when in 16:9 mode.
Does anyone know about CVBS, and has an idea why this happens ?
Here is fbset output:
