From f2ceec7fb2e1b7a182eb737216fe3214a743247d Mon Sep 17 00:00:00 2001 From: Katsuya Matsubara <matsu@igel.co.jp> Date: Wed, 14 Mar 2012 21:19:31 +0900 Subject: [PATCH 01/31] sys/v4l2/gstv4l2: fix the depth value for RGB32 The 'depth' value for RGB32 must be 24 rather than 32. This changes conversion code between color format representaion in caps and V4L2 definition. --- sys/v4l2/gstv4l2object.c | 17 ++++++++++------- 1 file changed, 10 insertions(+), 7 deletions(-) diff --git a/sys/v4l2/gstv4l2object.c b/sys/v4l2/gstv4l2object.c index 81d1cb7..2c1bde4 100644 --- a/sys/v4l2/gstv4l2object.c +++ b/sys/v4l2/gstv4l2object.c @@ -1208,14 +1208,16 @@ gst_v4l2_object_v4l2fourcc_to_structure (guint32 fourcc) b_mask = 0xff0000; break; case V4L2_PIX_FMT_RGB32: - bpp = depth = 32; + bpp = 32; + depth = 24; endianness = G_BIG_ENDIAN; r_mask = 0xff000000; g_mask = 0x00ff0000; b_mask = 0x0000ff00; break; case V4L2_PIX_FMT_BGR32: - bpp = depth = 32; + bpp = 32; + depth = 24; endianness = G_BIG_ENDIAN; r_mask = 0x000000ff; g_mask = 0x0000ff00; @@ -1480,9 +1482,10 @@ gst_v4l2_object_get_caps_info (GstV4l2Object * v4l2object, GstCaps * caps, #endif } } else if (!strcmp (mimetype, "video/x-raw-rgb")) { - gint depth, endianness, r_mask; + gint bpp, depth, endianness, r_mask; gst_structure_get_int (structure, "depth", &depth); + gst_structure_get_int (structure, "bpp", &bpp); gst_structure_get_int (structure, "endianness", &endianness); gst_structure_get_int (structure, "red_mask", &r_mask); @@ -1499,10 +1502,10 @@ gst_v4l2_object_get_caps_info (GstV4l2Object * v4l2object, GstCaps * caps, V4L2_PIX_FMT_RGB565 : V4L2_PIX_FMT_RGB565X; break; case 24: - fourcc = (r_mask == 0xFF) ?
