Subject: [PATCH 179/196] V4L2: Increase threshold for switching between video
|
|
& stills
|
|
|
|
The threshold used to be hard and fast at 1280x720 and failed if
|
|
either width or height exceeded those limits. Now it limits it at
|
|
a pixel count of 1280*720 (ie 921600), so 1024x768 is now considered
|
|
a video mode.
