From b796fb6ed032b0ccdb769b3b3bce5fb2b186a8f8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jean-Fran=C3=A7ois=20Moine?= Date: Wed, 10 Aug 2011 07:32:57 -0300 Subject: [media] gspca - main: Better values for V4L2_FMT_FLAG_COMPRESSED MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
