Hi.
Thanks for your reply.
First of all, we have already tried like that. But, it was not working.
Before this, we have already checked our register configureation in
s5k4ecgx.h is working on another MCU with firmware.
I think this probem occurs on fimc of Kernel and SecCameraHWInterface.cpp
of Android.
Our kernel version is 3.0.15 and android vesion is 4.0.4
I'm looking into these sources but I think there's no source code about Raw
Bayer.
There are something only for YUV and RGB.
So, I added some source cods as follwings.
For example,
@ kernel/drivers/media/video/samsung/fimc/fimc_capture.c
static const struct v4l2_fmtdesc capture_fmts[] = {
. . .
{
.index = 13,
.type = V4L2_BUF_TYPE_VIDEO_CAPTURE,
.flags = FORMAT_FLAGS_PLANAR,
.description = "YUV 4:2:0 planar, Y/Cr/Cb",
.pixelformat = V4L2_PIX_FMT_YVU420,
}, {
.index = 14,
.type = V4L2_BUF_TYPE_VIDEO_CAPTURE,
.description = "JPEG encoded data",
.pixelformat = V4L2_PIX_FMT_JPEG,
},
// JJongspi
{
.index = 15,
.type = V4L2_BUF_TYPE_VIDEO_CAPTURE,
.description = "V4L2_PIX_FMT_SBGGR10",
.pixelformat = V4L2_PIX_FMT_SBGGR10,
}, {
.index = 16,
.type = V4L2_BUF_TYPE_VIDEO_CAPTURE,
.description = "V4L2_PIX_FMT_SGBRG10",
.pixelformat = V4L2_PIX_FMT_SGBRG10,
}, {
.index = 17,
.type = V4L2_BUF_TYPE_VIDEO_CAPTURE,
.description = "V4L2_PIX_FMT_SGRBG10",
.pixelformat = V4L2_PIX_FMT_SGRBG10,
}, {
.index = 18,
.type = V4L2_BUF_TYPE_VIDEO_CAPTURE,
.description = "V4L2_PIX_FMT_SRGGB10",
.pixelformat = V4L2_PIX_FMT_SRGGB10,
},
};
void CameraHardwareSec::initDefaultParameters(int cameraId) {
parameterString =
CameraParameters::PIXEL_FORMAT_YUV420P; // "yuv420p"
parameterString.append(",");
parameterString.append(CameraParameters::PIXEL_FORMAT_YUV420SP);
// "yuv420p,yuv420sp"
// JJongspi
parameterString.append(",");
parameterString.append(CameraParameters::PIXEL_FORMAT_BAYER_RGGB);
parameterString.append(",");
parameterString.append(CameraParameters::PIXEL_FORMAT_BAYER_GRBG);
p.set(CameraParameters::KEY_SUPPORTED_PREVIEW_FORMATS,
parameterString); // "preview-format-values"
// p.setPreviewFormat(CameraParameters::PIXEL_FORMAT_YUV420P);
// p.setPreviewFormat(CameraParameters::PIXEL_FORMAT_BAYER_RGGB); //
JJongspi
p.setPreviewFormat(CameraParameters::PIXEL_FORMAT_BAYER_GRBG); //
JJongspi
};
I added some source codes like above and modified other files.
But android logcat said "01-02 05:38:34.610: E/SecCamera(1202): int
V4L2_PIX_2_HAL_PIXEL_FORMAT(int)::unmatched V4L2_PIX color_space(808534338)"
Do I have to change the souce code version??
Please help me.
Thanks.
Regards.
