I used this command vision.VideoFileReader(<myY800.avi>) to run the file, and I have got the error:
Error using dspmmfileinfo>tryVideoReader (line 271) The file requires the following codec(s) to be installed on your system: Y800 The specified file is: data/v3100.avi
Can I know how to solve it?

On a Windows system you can simply install the codec by installing the driver for a USB33U-camara by Imagingsource. This driver doesn't need an attached camera, by it installs the codec. Go to www.theimagingsource.com and install the "Device Driver for all 33U, 37U, 38U series, polarization USB cameras and the DFG/HDMI converter." (link: https://www.theimagingsource.com/support/downloads-for-windows/device-drivers/icwdmuvccamtis33u/ ) . Attention, not the general usb driver from imagingsource, it requires an attached camera. In addition for matlab, if you extract images from the avi, those are always as rgb images, identical in red green and blue. Use simply rgb2gray(img) to get the 8-bit grayscaled images. Do not convert the uncompressed Y800-avi to compressed mp4, you will lost information.

you may actually need to change the format of this video into mp4.
