The warning is clear: Use VideoReader instead of avioread. See the documentation of VideoReader for more details.

But the error might be serious: Matlab cannot find the compressor of the AVI file. This is a problem of the AVI file and you have to install the required compressor on your computer, what cannot be solved from the Matlab side. Inspect the AVI file to find out, which compressor is needed and search in the internet.
