If you insert a video from an external folder of the Unity build program into VideoPlayer as a URL and run it, it runs normally at first.
If you change the video multiple times and run it, an error occurs at some point where the video does not play.

Videos that do not play are videos that previously played normally.

Then fix the errors. That’s what software engineers DO.

The complete error message contains everything you need to know to fix the error yourself.

The important parts of the error message are:

  • the description of the error itself (google this; you are NEVER the first one!)
  • the file it occurred in (critical!)
  • the line number and character position (the two numbers in parentheses)
  • also possibly useful is the stack trace (all the lines of text in the lower console window)

Always start with the FIRST error in the console window, as sometimes that error causes or compounds some or all of the subsequent errors. Often the error will be immediately prior to the indicated line, so make sure to check there as well.

All of that information is in the actual error message and you must pay attention to it. Learn how to identify it instantly so you don’t have to stop your progress and fiddle around with the forum.
