Actually 0 or more. Usually you return 1 if you just support the sensor format in pass-through mode. If you return more, that usually means, that in addition to pass-through you can also convert that sensor format to some other format. > In my case, when the sensor supports YUYV, I'll return 2 and update the xlate > array with 2 entries, instead of just one, is that right? Right - because you can pass YUYV 1-to-1 and also convert it to nv12.
