Raw only works for first picture

[TheLastMutt]

Raw layer needs to be requested every time a picture is taken, otherwise it works only once after changing the setting. See comment in Raspistill.c:

// Same with raw, apparently need to set it for each capture, whilst port
// is not enabled

To activate raw every time it is needed, I just added this in RaspiMCmds.c:

      case im:
         if(cfg_val[c_raw_layer] == 1) {
           cam_set(c_raw_layer);
         }
         capt_img();
         break;

That seems to work for single capture. Timelapse probably needs something like this as well.

OK. Thanks for that. I don't use raw myself so hadn't noticed that setting raw as a camera parameter doesn't seem to persist in the MMAL.

I have put your logic at the top of the capt_img function instead of in commands as that means it will work for time lapse as well.
