When playing a movie and you press the lowercase o key on the keyboard, the movie starts playing backwards. One has to pause the movie and then click play to fix the issue. Shift O does not mess things up. I could not find any other keys causing strange behaviours. I will submit this as a bug report unless someone is able to explain why this behaviour. If you want to try this for yourself, open the FolderMoviePlayer example that Xojo provides. It is in the examples folder, graphics & multimedia etc. Run the program and open a folder of videos/movies, while playing press the letter o (lowercase) key and its starts playing backwards. I tested this with Big Sur OS as well as Mojave and the issue is reproducible in both cases. All updates have been done.
I would guess it’s a QuickTime shortcut and not a Xojo issue (since Xojo uses QuickTime). Have you tried it in the real QuickTime app?
(sorry, I don’t have time now to try myself)
Yes, just for fun. I loaded the same video into quicktime and it works properly. I even looked into my Mac OS keyboard shortcuts and I could not find any entries for the letter o. No single letter does anything except for the space bar which stops and starts the video.
Here are some more info. I have submitted this as a bug. If you want to try this, do the following…
OS: OS X 11.6
Xojo: Xojo 2021r2.1
Steps: Create a new project. Drag the MoviePlayer control into the window. Drag a video into the side contents. Change the initial state of the MoviePlayer Control from none to the video you dragged in.
Run the project. Resize your window so you can see the controller. Let movie play for a few seconds, then press o on the keyboard. Movie plays in reverse and the controller icon changes from pause to play. This issue can be duplicated on Mojave that is on a different computer.
Expected Result:
I expect the keystroke to be ignored.
Actual Result:
Video plays in reverse.
Workarounds:
Don’t press the letter o while playing movie.
Sorry, I wasted your time.
QuickTime was used by Xojo’s MoviePlayer, yes, but that was until years ago. I haven’t noticed the change.
My apologies.
