I get the same error message if I simply call VideoReader from the command line as

 >> VideoReader

 Error using VideoReader (line 135)
 FILENAME must be specified.

As per the documentation at VideoReader you need to provide a file name as

 >> vidObj = VideoReader('xylophone.mp4');

or using another file name that is specific to your work.

yes i provide a file name and specifically i have an .avi file,but i still have these errors:

Error using VideoReader/init (line 607) The filename specified was not found in the MATLAB path.

Error in VideoReader (line 172) obj.init(fileName);

Please show your call to VideoReader

[abbxucy11]

 img =  frame2im(VideoReader(video,1));

basically i want to create an image img that represents the first frame of the video

[Walter Roberson]

Provided that video has been initialized as

   video = VideoReader('SomeFileName.avi');

then

   img = readFrame(video);

There is no frame2im() requires for this use.

If you have a sufficiently old MATLAB then you might need

img = read(video, 1);
