MATLAB: Read .avi file on Matlab

read videovideo processingvideoreadervision.videofilereader

Dear community,
I am running Matlab R2019a and I have tried the following commands to read .avi files but neither work. Specifically:
1) Command: vision.VideoFileReader
    workspace;
    matlab.video.read.UseHardwareAcceleration('on');
    filename='Droplet1_Route1_6.0V_16.12.avi';    
    videoFReader = vision.VideoFileReader(filename);
    videoPlayer = vision.VideoPlayer;
    while ~isDone(videoFReader)
   videoFrame = videoFReader();
   videoPlayer(videoFrame);
   pause(0.1)
    end
    release(videoofReader);
    release(videoPlayer);
Error:
>> trial_video_read
Error using vision.VideoFileReader
Invalid input file.
2) Command: videoReader
fontSize = 22;
video_input= VideoReader('Droplet1_Route1_6.0V_16.12.avi');
Error:
Error using VideoReader/initReader (line 729)
The file requires the following codec(s) to be installed on your system:
cvid
Error in audiovideo.internal.IVideoReader (line 148)
initReader(obj, fileName, currentTime);
Error in VideoReader (line 98)
obj@audiovideo.internal.IVideoReader(varargin{:});
Error in video_frames (line 2)
video_input= VideoReader('Droplet1_Route1_6.0V_16.12.avi');
VideoReader works with .mp4 files but why doesn't it work with .avi?
I would appreciate any help.
Thank you in advance for your time,
Best regards
