-    Note that there is a possibility that the value will be adjusted to follow remote capability. For example, if remote signals that maximum resolution supported is 640 x 480 and locally the encoding direction size is set to 1280 x 720, then 640 x 480 will be used.

+    -  The library will find the closest size/ratio that the capture device supports. Application should choose the size ratio that the capture device supports, otherwise the video might get stretched. 
+For example, if the device capture supports 640x480 and 1280x720 and the size is set to 500x500. The device camera will be opened at 640x480 and later converted to 500x500 which might. 
  b. For decoding direction, two steps are needed:
     1. {{{pjmedia_vid_codec_param.dec_fmt.det.vid.size}}} should be set to the highest value expected for incoming video size.
