Subject: [media] gspca - main: Better values for V4L2_FMT_FLAG_COMPRESSED Author: Jean-François Moine <[email protected]> Date: Wed Aug 10 07:32:57 2011 -0300 In vidioc_enum_fmt_vid_cap, the 'compressed' flag was set from the pixelformat, and all pixelformats were not treated. Now, images are told as compressed when the image size is smaller than its number of pixels.
