QA:Testcase webcam options

Jump to: navigation, search

Description

This test case tests whether configuring various settings for a webcam works correctly


How to test

  1. Start the system, plug in and turn on (if necessary) the webcam
  2. Run the Package-x-generic-16.pngcheese webcam application (Sound & Video -> Cheese Webcam Booth in the system menu)
  3. Open the Preferences dialog and try changing the resolution
  4. Install the package Package-x-generic-16.pngv4l2ucp
  5. From a console, run v4l2ucp /dev/video0 - change video0 if your webcam shows up at a differently-numbered dev node
  6. Try changing the various options that are present and check if they are reflected in the output (you can monitor with Cheese, or v4l2ucp's preview mode)

Expected Results

  1. Changing the resolution setting should change the resolution (size) of recorded video or images, so you will have to record some video or take a picture to check this setting (the size of the Cheese window does not change as you adjust the resolution). There should be no black borders around the image. If there are, try resizing the Cheese window to get rid of them. If you cannot, file a bug
  2. v4l2ucp changes should be correctly reflected in the camera output, and should not cause buggy behaviour like the output failing or the camera shutting off
