How can I use the ColorChannels function of VideoWriter in VideoReader?

I am currently making a code in which an input video comes in and I need to check the number of color channels it has. The function I need is in videoWriter but I need to use it in videoReader because I am not going to create a new video.

Thank you very much in advance.

Hii,

By using whos func youcan get the info of number of color channels

Below is an example code for it

 v = VideoReader('xylophone.mp4');
    frame=read(v,1);
    whos frame;

Name Size Bytes Class Attributes

frame 240x320x3 230400 uint8

Where Size(2400x320x3) 3-gives the number of color channels

3-RGB

1-Grey
