I get the error videos/*.jpg not found. Please help

Well you're missing a trailing quote, but that won't give that error. Did you follow the guidelines for the second example of this section of the FAQ:

'/' as file separator should also work on Windows systems too. (At least it does on mine.)

(Just for convenience issues: fullfile('videos', '*.jpg') is equivalent to your statement and comes in quite handy for deeper stacked directory structures.)

  • Are you in the right working directory? Check with pwd and/or check whether the results of dir (without any parameters) contains a directory called "videos".
  • If there is no file matching the pattern, this error will appear. You won't simply get an empty result (although I agree this should be the case).
  • Did you eventually forget about the case sensitivity of Linux systems?
