Hi,

We plan to use the composite video input into the TVP5146 which will be digitized and pulled through the BT656 interface to the DM365. The analog camera we have sourced however is best mounted within our housing if it is placed upside down. My query is thus, is it possible to permanently vertically invert all incoming video in software? Is this something semi-trivial or would it be better to account for this in housing? Any side-effects (ie increased processor requirements?)

I cannot find anything in the TVP5146 spec regarding inversion and unfortuanely do not even know yet where I could even start to look on the linux side. (any heads up here would also be appreciated although for now I primarily just need a yes / no / possible repercussions answer in order to allow our guys to continue with the HW).

Sincerely,
NickA

    Hi Nick,

    The frame cannot be inverted by the TVP5146.  This would have to be done by the processor after frame capture.
